Top X Saltation Mvc Together With Balance Annotations Alongside Examples For Coffee Programmers

Hello guys, welcome to my 3rd article on exploring essential annotations from the Spring framework, the most pop framework for Java development. In the offset article, I convey shared some of the most useful Spring Framework annotations, which were based upon Core Spring functionalities similar dependency injection, inversion of control, in addition to configuration, in addition to inward the instant article, nosotros convey learned nigh of import Spring Cloud annotations like @EnableConfigServer, @EnableEurekaSever, in addition to @EnableDiscoveryClient. Now that you lot know those essential Spring annotations it's fourth dimension to motion towards Spring MVC in addition to REST, 1 of the most used parts of Spring Framework.

In this article, you lot volition acquire some of the essential Spring MVC in addition to REST annotations similar @Controller, @RequestMapping, in addition to @RestController. These annotations are really useful for creating Spring-based Java spider web application in addition to RESTful spider web services.

I specially similar Spring MVC's back upwardly for developing RESTful spider web services inward Java. As I convey explained inward my before article 7 reasons to utilisation Spring MVC for REST inward Java, it provides convenient annotations similar @RestController, @ResponseBody, in addition to @ResponseStatus to create fully functional REST APIs inward Java.

In add-on to exploring total Spring MVC annotations similar @RequestMapping, @RequestParam, in addition to @PathVariable, we'll also explore those which are immensely helpful for developing REST APIs inward Java.

Btw, if you lot convey worked inward Spring MVC thus you lot should already convey some basic ideas nigh these annotations, but if you lot don't convey whatever prior sense in addition to only started amongst Spring framework in addition to Spring MVC thus I propose you lot to offset acquire through a comprehensive course of written report similar Spring Framework 5: Beginner to Guru course of written report on Udemy.  One of the most useful courses on Spring framework.

10 Spring MVC in addition to REST annotations for Java developers

Without wasting whatever to a greater extent than of your time, hither is my listing of some of the must-know Spring MVC in addition to REST annotations for Java developers. If you lot convey used Spring MVC to create a spider web application or RESTful applications thus you lot should already move familiar amongst these but if you lot haven't don't worry, you'll acquire inward this article.

Btw, I'll non acquire inward besides much particular nigh roofing every unmarried alternative in addition to functionality of these annotations, only to proceed this article inward reasonable length, but volition give you lot resources similar Spring inward Action majority where you lot tin acquire these annotations in addition to their utilisation inward depth.

1. @Controller

This annotation is used to brand a degree every bit spider web controller, which tin conduct maintain customer requests in addition to shipping a reply dorsum to the client. This is a degree flat annotation, which is position on top of your controller class. Similar to @Service in addition to @Repository it is also a stereotype annotation. If you lot are wondering what is the departure betwixt them thus you lot tin also run across this article to acquire to a greater extent than nigh their differences.

Here is an event of @Controller annotation inward Spring MVC:

@Controller public class HelloController{ // handler methods }

This is a uncomplicated controller degree which contains handler methods to conduct maintain HTTP asking for unlike URLs. You don't need to extend a degree or implement an interface to create the controller anymore.

2. @RequestMapping

The Controller degree contains several handler methods to conduct maintain unlike HTTP asking but how does Spring map a particular asking to a particular handler method? Well, that's done amongst the assist of the @RequestMapping annotation. It's a method flat annotation which is specified over a handler method.

It provides the mapping betwixt the asking path in addition to handler method. It also supports some advanced alternative which tin move used to specify split handler methods for unlike types of asking on the same URI similar you lot tin specify a method to conduct maintain GET request in addition to some other to conduct maintain POST asking on same URI.

Here is an event of @RequestMapping annotation inward Spring MVC:

@Controller public class HelloControler{    @RequestMapping("/")   public String hello(){     return "Hello Spring MVC";   } }

In this example, the dwelling page volition map to this handler method. So whatever asking comes to the localhost:8080 volition acquire to this method which volition render "Hello Spring MVC".

The value attribute of @RequestMapping annotation is used to specify the URL pattern but if at that topographic point are no to a greater extent than arguments thus you lot also omit that.

You tin also specify the HTTP method using RequestMethod attribute. If you lot are novel to Spring MVC, I propose you lot acquire through  @RequestParam annotation inward Spring MVC from my before article nigh the departure betwixt RequestParam in addition to PathVariable annotation:

@RequestMapping("/book") world String showBookDetails(  @RequestParam("ISBN") String ISBN, Model model){   model.addAttribute("ISBN", ISBN);   render "bookDetails"; }

If you lot access your spider web application which provides majority details amongst a query parameter similar below:

http://localhost:8080/book?ISBN=900848893

thus inward a higher house handler method volition move called because it is outpouring to the "/book" URL in addition to the query parameter ISBN volition move used to populate the method declaration amongst the same parent "ISBN" within showBookDetails() method.

You tin fifty-fifty utilisation a unlike parent of your choice. If you lot are interested inward learning to a greater extent than nigh @RequestParam annotation in addition to its diverse options thus Spring MVC For Beginners: Build Java Web App inward 25 Steps on Udemy is a bang-up house to start with.

4. @PathVariable

This is some other annotation which is used to remember information from the URL. Unlike @RequestParam annotation which is used to extract query parameters, this annotation enables the controller to conduct maintain a asking for parameterized URLs similar URLs that convey variable input every bit portion of their path like:

http://localhost:8080/books/900083838

If you lot desire to remember the ISBN let on "900083838" from the URL every bit method declaration thus you lot tin utilisation @PathVariable annotation inward Spring MVC every bit shown below:

@RequestMapping(value="/books/{ISBN}",                         method= RequestMethod.GET) world String showBookDetails(@PathVariable("ISBN") String id, Model model){    model.addAttribute("ISBN", id);    render "bookDetails"; }

The Path variable is represented within curly braces similar {ISBN}, which agency the portion later /books is extracted in addition to populated on method declaration id, which is annotated amongst @PathVaraible.

In short, this annotation binds placeholder from the URI to a method parameter within the handler method. This is immensely useful piece developing RESTful spider web services which contains useful information every bit portion of their URL.

5. @RequestBody

This annotation tin convert inbound HTTP information into Java objects passed into the controller's handler method. Just every bit @ResponseBody tells the Spring MVC to utilisation a message converter when sending a reply to the client, the @RequestBody annotations tell the Spring to notice a suitable message converter to convert a resources representation coming from a customer into an object.

Here is an example:

@RequestMapping(method=RequestMethod.POST, consumers= "application/json") world @ResponseBody Course saveCourse(@RequestBody Course aCourse){    render courseRepository.save(aCourse); }

This is 1 time to a greater extent than a really useful annotation piece developing RESTful spider web service inward Java using Spring framework in addition to 1 of the reasons why I dearest to write RESTful API using Spring.

If you lot are also interested inward developing RESTful application inward Java thus I propose going through Eugen Parachiv's REST amongst Spring Certification class on Baeldung. He has shared his years of sense inward developing REST-based applications using Spring inward this course.

6. @ResponseBody

The @ResponseBody annotation is 1 of the most useful annotations for developing RESTful spider web service using Spring MVC. This annotation is used to transform a Java object returned from he a controller to a resources representation requested past times a REST client. It tin completely bypass the persuasion resolution part.

Here is an event of @ResponseBody annotation inward Spring MVC:

@RequestMapping(method=RequestMethod.POST,consumers= "application/json") world @ResponseBody Course saveCourse(@RequestBody Course aCourse){   render courseRepository.save(aCourse); }

This is the same every bit the previous event but the @ResponseBody is used to betoken that the reply returned past times this method volition move converted into a resources which the customer tin consume.

If you lot convey created whatever RESTful spider web service amongst Spring MVC thus you lot know that nosotros need to annotate each method which generates REST reply amongst the @ResponseBody annotation but amongst the introduction of @RestController, nosotros tin avoid this.

7. @RestController

This is convenience annotation for developing RESTful spider web service amongst Spring MVC framework. The @RestController is a combination of @Controller in addition to @ResponseBody, which was introduced inward the Spring 3.4 version.

When you lot annotate a controller degree amongst @RestController it does 2 purposes, first, it says that the controller degree is treatment a asking for REST APIs in addition to instant you lot don't need to annotate each method amongst the @ResposneBody annotation to signal that the reply volition move converted into a Resource using diverse HttpMessageConverers.

Here is an event of @RestController annotation inward Spring MVC:

@RestController class HelloControler{  @RequestMapping("/") public String hello(){   return "Hello Spring Booot"; }  }

You tin run across that at that topographic point is no @ReseponseBody annotation is required to generate RESTful response. Before @RestController, Java developer used @Controller on top of the degree in addition to annotated each handler method amongst @ResponseBody annotation.

Spring designer saw this in addition to brand life easier past times introducing @RestController. If you lot are interested, you lot tin acquire to a greater extent than nigh it on RESTful Web Services amongst Java in addition to Spring, a comprehensive course of written report for developing a existent globe in addition to secure REST API amongst Java in addition to Spring.
You volition also acquire about Implementing API calls, Sign-up, sign-in, e-mail verification, password reset, update, delete in addition to fifty-fifty how to deploy RESTFul Java apps on Amazon AWS Cloud.

8. @SprinbBootApplication

This is a relatively novel annotation but really useful if you lot are using Spring Boot for creating Java spider web application amongst Spring. This unmarried annotation combines 3 annotations similar @Configuration, @EnableAutoConfiguration, in addition to @ComponentScan. If you lot utilisation Spring Boot, thus you lot tin run your application without deploying into a spider web server, every bit it comes amongst an embedded Tomcat server.

When you lot annotated your Main degree amongst @SpringBootApplication thus it enables Java-based configuration every bit good every bit ingredient scanning in addition to auto-configuration characteristic of Spring Boot, which tin magically laid things for you lot past times only dropping the required JAR into classpath.

hither is an event of using @SpringBootApplicaiton annotation inward Spring:

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;  @SpringBootApplication  // same every bit @Configuration @EnableAutoConfiguration @ComponentScan public class SpringBootApp{   public static void main(String[] args) {   SpringApplication.run(SpringBootApp.class, args);  }  }

Since Spring Boot provides many features to brand Java evolution amongst Spring easier, I propose you lot to utilisation Spring Boot going forward. If you lot are novel to Spring kick then Spring Boot MasterClass course on Udemy is 1 of the valuable resources to acquire in addition to original Spring Boot.

9. @EnableAutoConfiguration

This is some other Spring kick annotation which enables the auto-configuration feature, which makes Spring jurist the configuration based on the JAR presents inward the classpath.

This is genuinely the original annotation which was used to enable/disable auto-configuration, nowadays from the really offset liberate of Spring Boot. Since it was constantly used amongst @Configuration in addition to @ComponentScan on an before version of Spring boot, they convey come upwardly up amongst a convenience @SpringBootApplication annotation.

Though you lot tin yet utilisation @EnableAutoConfiguration annotation if you lot desire to customize or convey some command over auto-configuration.

For example, you lot tin exclude surely classes from auto-configuration every bit shown inward the next event from my before post nigh the departure betwixt @SpringBootApplication in addition to @EnableAutoConfiguration inward Spring boot:

@Configuration @EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class}) public class MyConfiguration {   //.. Java code }

If you lot desire to acquire to a greater extent than nigh this annotation thus Spring Boot inward Action past times Craig Walls is 1 of the best resources to start with.

10. @ResponseStatus

This annotation tin move used to override the HTTP reply code for a response. You tin utilisation this annotation for mistake treatment piece developing a spider web application or RESTful spider web service using Spring. Here is an event of @ResponseStatus inspired past times my favorite Spring inward Action book:

@Exceptionhandler(BookNotFoundException.class) @ResponseStatus(HttpStatus.NOT_FOUND) public Error bookNotFound(BookNotFoundException bnfe){   long ISBN = bnfe.getISBN();   return new Error(4, "Book [" + ISBN + "] non found"); }

Here nosotros are returning an mistake if the majority for given ISBN is non establish inward our library in addition to nosotros convey used @ResponseStatus to override the HTTP condition code every bit 404 to betoken customer a missing resource.


That's all nigh some of the essential Spring MVC in addition to REST annotations. As a Java developer, you lot should move familiar amongst these annotations, especially if you lot are using Spring MVC for creating a spider web application or RESTful spider web service inward Java. If you lot desire to acquire to a greater extent than nigh these annotations in addition to diverse options to configure in addition to utilisation them, hither are some resources you lot tin consult.

For those who don't know, the Spring framework is i of the most pop structures for Java applications, which aims to simplify Java development. It revolutionized the Java evolution when it initially came amongst concepts of  Dependency Injection as well as Inversion of Control, which made writing testable as well as maintainable Java application. 

But the Spring framework but didn't halt there; it also provides useful API to Java programmers. The best thing is that Spring has been kept evolving since its inception as well as addressing Java developers delineate of piece of occupation concern inwards unlike areas.

Spring framework is divided into many unlike modules similar Spring MVC, Spring Integration, Spring Batch, Spring LDAP, Spring Security, Spring Boot, Spring Cloud, as well as several other modules, which focus on a special area.

For example, Spring Boot tries to acquire inwards fifty-fifty easier to exercise the Spring framework past times reducing the amount of configuration you lot demand to pose inwards for Spring itself. Spring Cloud is evolving to locomote out the best framework for developing cloud-based Java frameworks as well as Microservices, which is a demand for the future, as well as Spring Security has established itself equally the go-to framework for safety Java spider web applications.

Based on your piece of occupation experience, the Interviewer tin give notice enquire questions from heart as well as mortal Spring or these modules. That's why, piece preparing the Spring interview query focus on Spring core, Spring Security, as well as Spring API, these are principal areas from where the interviewer asks questions.

If you lot have got working sense inwards Spring-based Java projects, you lot tin give notice rapidly respond most of these Spring questions from several Java interviews. Still, if you lot don't have got whatever prior sense as well as but learning Spring,  I advise you lot to locomote out through Spring Framework 5: Beginner to Guru course on Udemy to larn Spring fundamentals earlier attempting these questions.

Spring Interview Questions as well as Answers

Now that you lot know the importance of Spring Framework for Java developers as well as ready to have got on Spring questions on your side past times side interview, let's encounter but about often asked questions on the Spring framework on Java interviews:


1) What is the Spring framework? Why Java programmers should exercise the Spring framework? (answer)
Very mutual Spring interview question, Spring is a framework which helps Java programmer inwards development. Spring provides Dependency Injection as well as IOC container, Spring MVC flow, as well as several useful API for Java programmer.


2) What is the default compass of edible bean inwards the Spring framework? (answer)
The default compass of a Spring edible bean is the Singleton scope, as well as inwards the spider web application default compass of a saltation edible bean inwards asking scope. Singleton edible bean way the same instance of a edible bean is shared amongst all other beans, piece asking compass way a edible bean is endure entirely for a request.


3) Does Spring singleton beans are thread-safe?
No, Spring singleton beans are non thread-safe. Singleton doesn't hateful edible bean would be thread-safe.


4) What is the Dependency Injection blueprint pattern? (answer)
Dependency Injection is i of the blueprint patterns, which allows injecting dependency on Objects, instead of object resolving the dependency.


5) What is Inversion of Control concept, how does Spring back upward IOC? (answer)
The unproblematic pregnant of inversion of the command way that at i time the framework, Spring is responsible for creating objects, wiring dependencies, as well as managing their life-cycle instead of a developer, which was the illustration before. That's where command is inverted from developer to framework.


6) What is Spring MVC? Can you lot explicate How i asking is processed? (answer)
Spring MVC is a framework to railroad train Java spider web applications. It provides an implementation of MVC or Model View Controller architecture, which is built on the separation of concerns as well as makes the evolution of Java spider web application easy. In gild to exercise this inwards your project, you lot demand to larn Spring as well as include its JAR file.

Spring MVC framework besides supplies an inbuilt persuasion resolver for selecting views. See Spring Master Class - Beginner to Expert to larn to a greater extent than close how Spring MVC internally works.

7) What is the View Resolver pattern? how it industrial plant inwards Spring MVC
View Resolver pattern is a J2EE pattern that allows a spider web application to dynamically conduct its persuasion technology, e.g. HTML, JSP, Tapestry, JSF, XSLT, or whatever other persuasion technology.

In this pattern, View resolver holds a mapping of unlike views, controller render cite of the view, which is hence passed to View Resolver for selecting an appropriate view. 


8) How do you lot create a controller inwards Spring? @Controller vs. @RestController? (answer)
Influenza A virus subtype H5N1 controller is cipher but a class, besides known equally a edible bean inwards Spring terminology. If you lot are using annotation, hence you lot tin give notice create a controller past times using @Controller annotation.

For RESTful spider web service, you lot tin give notice besides create REST controllers past times using the @RestController annotation, as well as inwards that case, you lot don't demand to exercise the @ResponseBody musical note explicitly to nation Spring how it needs to respond.

Btw,  if you lot are interested inwards learning to a greater extent than close how to railroad train RESTful Web Service using Spring framework, I advise taking a expect at the REST amongst Spring course by Eugen Paraschiv of Baeldung. It's i of the comprehensive class which non entirely covers basics but besides advanced concept similar versioning, testing, as well as deploying REST API inwards production.


9) What types of dependency injection are supported past times Spring Framework? When do you lot exercise Setter as well as Constructor Injection, the pros as well as cons?
There are two types of dependency injection supported past times Spring, constructor based injection, as well as setter-based injection.

Both types have got their ain advantages as well as disadvantages; you lot should exercise Constructor injection when an object's dependencies are non optional, as well as they must endure initialized amongst their dependencies.

Also, exercise constructor injection if the gild of initialization or dependency matters because, inwards Setter based injection, you lot cannot impose whatever order. Use setter injection when dependencies are optional. See the difference betwixt setter vs. constructor injection inwards Spring for a to a greater extent than detailed answer.


10) Can nosotros exercise to a greater extent than than i configuration file for our Spring project?
Yes, you lot tin give notice exercise equally many equally you lot want, all you lot demand to is import them inwards the principal Spring configuration file which you lot volition charge from your program.


11) What is Spring Security?
Spring safety is a projection nether the saltation framework umbrella, which provides back upward for safety requirements of firm Java projects.

Spring Security, formerly known equally aegis security, provides out of box back upward for creating a login screen, Remember me cookie support, securing URL, authentication provider to authenticate the user from the database, LDAP as well as inwards memory, Concurrent Active Session management back upward as well as much more.

In gild to exercise Spring safety inwards a Spring MVC based project, you lot demand to include spring-security.jar as well as configure it inwards the application-Context-security.xml file, you lot tin give notice cite it whatever you lot want, but brand certain to render this to ContextLoaderListener, which is responsible for creating Spring context as well as initializing dispatcher servlet. You tin give notice farther encounter Learn Spring Security Certification Class larn to a greater extent than close authentication, authorization, as well as session command using Spring Security.

12) What is the deviation betwixt ApplicationContext as well as BeanFactory inwards Spring framework? (answer)


13) How do you lot telephone band a stored physical care for past times using the Spring framework? (answer)


14) What do the JdbcTemplate as well as JmsTemplate class offering inwards Spring? (answer)
They offering a criterion way to exercise JDBC as well as JMS API, without writing the boiler code required to piece of occupation amongst those API.

15) How do you lot command concurrent Session on Java spider web application using Spring Security? (answer)
You tin give notice exercise Spring Security to command a release of active sessions inwards Java spider web application. Spring safety framework provides this characteristic out of the box, as well as when enabled, a user tin give notice entirely have got i active session at a time.


16) Explain Spring MVC stream amongst a unproblematic illustration similar starting from Container receives a asking as well as forrad to your Java application?
I have got explained to them from start to halt inwards my article how does Spring MVC industrial plant article internally; you lot tin give notice banking company gibe that for a detailed answer.


17) What is the deviation betwixt Spring MVC as well as Spring core?
The Spring MVC is component of the Spring framework, which helps you lot to railroad train Java spider web application using model spider web controller pattern, piece Spring Core provides the Dependency injection as well as Inversion of Control. The Spring Container is component of Spring core.

Both functionalities come upward inwards unlike JAR files. If you lot are developing but a heart as well as mortal Java application using Spring, hence you lot but demand Spring Core, but if you lot are developing a Web application, hence you lot demand spring-mvc.jar equally well. See answer)


24) Difference betwixt @SpringBootApplication as well as @ContextConfiguration musical note inwards Spring Boot? (answer)


25) What is the exercise of DispatcherServlet inwards Spring MVC? (answer)


26) What is the role of InternalResourceViewResolver inwards Spring MVC (answer)


27) What is the deviation betwixt @Autowired as well as @Inject musical note inwards Spring? (answer)


28) Difference betwixt @RequestParam as well as @PathVariable inwards Spring MVC? (answer)

29) Difference betwixt @Component, @Service, @Controller, as well as @Repository annotations inwards Spring MVC? (answer)


30) How to eat RESTful Web Service using Spring MVC? (answer)


31) Difference betwixt @SpringBootApplication as well as @EnableAutoConfiguration annotations inwards Spring Boot? (answer)

These were but about of the Core Spring framework as well as MVC Interview questions from my collection, I have got given brusk answers for most of these Spring interview question. I advise to inquiry to a greater extent than or read along those Spring query to ready for follow-up Spring interview questions. Some Spring MVC questions are tricky similar Struts as well as Spring integration as well as tin give notice endure entirely answered past times experienced Java plan amongst two to 4-year sense inwards the Spring MVC framework.

Can Yous Brand A Flat Static Inwards Java? Interview Question

This is i of the tricky questions inwards Java because in that place is no straight forward. Yes in addition to No reply here. You cannot brand a top-level aeroplane static inwards Java, but Yes, you tin plow over the sack brand a nested aeroplane static inwards Java. In fact, it is fifty-fifty advised (see Effective Java) to prefer a nested static class inwards Java than normal inner classes. Now, the query comes what is a top-level class, in addition to what is a nested aeroplane inwards Java? Well, you lot tin plow over the sack declare multiple classes inwards a unmarried Java source file. Influenza A virus subtype H5N1 aeroplane is said to survive the exceed aeroplane if it is non within whatever other class, in addition to a aeroplane that is within roughly other aeroplane is known every bit nested class. You tin plow over the sack do a nested aeroplane within roughly other top-level or roughly other nested aeroplane inwards Java. This is the aeroplane that tin plow over the sack survive static inwards Java.

Some of you lot must survive wondering what the do goodness of making a aeroplane static inwards Java is? Why would i brand a aeroplane static? In lodge to reply this question, let's revise the concept of what does static hateful inwards Java? Well, a static keyword tin plow over the sack survive used amongst a class, method or variable inwards Java in addition to anything static belongs to the class, which agency a static method tin plow over the sack survive accessed in addition to called simply past times using aeroplane name, i.e. you lot don't postulate to do an illustration of the aeroplane to telephone telephone this method because it belongs to class.

The same is truthful amongst static fellow member variable every bit well; you lot tin plow over the sack access them without creating an illustration of the class. They tin plow over the sack survive accessed past times using aeroplane name, e.g. Class.variable.

Influenza A virus subtype H5N1 non-static nested class, every bit good known every bit the Inner class on the mitt ever postulate an illustration of enclosing class, which agency you lot cannot do an illustration of the nested aeroplane without start creating an illustration of the outer class.

This challenge tin plow over the sack survive overcome past times declaring the nested aeroplane static inwards Java i.e. you lot tin plow over the sack straight do an illustration of a nested aeroplane without start creating an object of enclosing class.


This is the unmarried most of import argue fhy you lot should brand na ested aeroplane static inwards Java , nd this is what advised past times Joshua Bloch inwards his aall-timeclassic Java book, Effective Java.

Like whatever other inwardness Java question, nosotros should verify if compiler back upwardly theses fact or not. To banking concern fit whether nosotros can brand a aeroplane static inwards Java or not, we'll effort both exceed aeroplane in addition to a nested aeroplane static.

Using static modifier amongst a exceed aeroplane class

Let's effort to role the static modifier amongst a exceed aeroplane storey i.e. a aeroplane which is non within whatever other class. Here is the code to do that, when you lot compile this code inwards Java from the dominance trouble you lot volition meet compile fourth dimension fault because this is non permitted inwards Java:

static aeroplane Top{  ... }

In Eclipse, every bit presently every bit type the code, I have next compiler error "Illegal modifier for the aeroplane Top; solely public, abstract & concluding are permitted". You volition have something similar when you lot compile this aeroplane using javac from the command line.

Using static modifier amongst a nested aeroplane inwards Java

Now, let's effort to role the static modifier amongst a nested aeroplane inwards Java i.e. a aeroplane which is within roughly other class. Here is the code to do that in addition to this fourth dimension you lot won't meet whatever compile fourth dimension error. I'll every bit good exhibit you lot how to do an illustration of the nested static aeroplane inwards Java. Influenza A virus subtype H5N1 nested aeroplane is named past times joining the refer of the top aeroplane class in addition to nested aeroplane amongst a point every bit shown below:

class Top{  static class Nested{  ...... } }  class Test{  public static void main(String args[]){    Top.Nested n = new Top.Nested(); // ok } }

You tin plow over the sack meet that in that place is no compile fourth dimension fault this time, which agency you lot tin plow over the sack brand a nested aeroplane static inwards Java. In fact, it is every bit good a best exercise to prefer nested static aeroplane over a non-static aeroplane inwards Java because of convenience (see Effective Java).

As you lot tin plow over the sack see, you lot don't postulate an illustration of enclosing or exceed aeroplane storey to do an illustration of the nested static class. Many Java classes follow this exercise e.g. LinkedList.Node in addition to Map.Entry is 2 pop examples of nested static aeroplane from JDK.


That's all nearly whether you lot tin plow over the sack brand a aeroplane static inwards Java. Influenza A virus subtype H5N1 static aeroplane is possible inwards Java but solely when if it is nested, you lot tin plow over the sack non brand a exceed aeroplane storey static inwards Java. Btw, don't confuse the give-and-take hither amongst a aeroplane amongst simply static methods e.g. java.lang.Math, they are every bit good known every bit a static class but that is the totally dissimilar thing.

All the give-and-take hither nearly whether you lot tin plow over the sack role the static modifier amongst a aeroplane or non in addition to every bit I explained, you lot tin plow over the sack solely role the static modifier amongst a nested aeroplane inwards Java. Trying to role a static modifier amongst a exceed aeroplane storey inwards Java.
