Top X Restful Spider Web Service Interview Questions For Coffee Developers

REST is an architectural way of developing spider web services which receive got acquire immensely pop inwards the final distich of years together with consequently gained a lot of importance inwards inwardness Java together with Java EE interviews. If y'all are a Java spider web developer together with so y'all are most probable run into a distich of questions from spider web services every fourth dimension y'all buy the farm for a Java spider web developer interview. One of the most frequent ane is difference betwixt REST together with SOAP spider web services, which I receive got of late answered there, but at that topographic point are lot many other goodness questions I receive got collected from friends together with my readers, which I receive got non nonetheless published. In this article, I am sharing those questions, mainly based on REST-style spider web services for your practise together with preparation.

Some of them are slowly to respond together with y'all volition uncovering them either inwards my weblog or yesteryear doing Google but a distich of them is genuinely interesting together with challenging together with required existent corporation sense inwards Java spider web service domain to answer. I travel out it to y'all guys for right away together with volition in all likelihood update this postal service alongside answers inwards nigh future.

If y'all don't uncovering respond of whatever REST interview inquiry together with so I advise y'all to accept a aspect at these 2 resources, Java Programming Interview Exposed and RESTful Web Services, y'all volition most probable uncovering your respond there.

RESTful Web Services Interview Questions 

Here is my listing of RESTful spider web services questions for senior Java developers who receive got a distich of years of sense developing both SOAP together with REST based spider web services. This is genuinely the minute exercise of my serial of Java spider web services based question, inwards the before article, I receive got shared approximately SOAP spider web services based questions. If y'all receive got non looked already, y'all may desire to accept a look.



Question 1 : What is REST?
Answer : REST is an architectural way of developing spider web services which accept payoff of ubiquity of HTTP protocol together with leverages HTTP method to define actions. REST stands for REpresntational State Transfer.


Question 2 : What is RESTFul Web Service?
Answer : There are 2 pop way to develop spider web services, using SOAP (Simple Object Access Protocol) which is XML based way to let out spider web services together with minute REST based spider web services which uses HTTP protocol. Web services developed using REST way is likewise known equally RESTful Web Services.


Question iii : What is HTTP Basic Authentication together with how it works?


Question four : Can y'all tell me which API tin last used to develop RESTFul spider web service inwards Java?
Answer : There are many framework together with libraries out at that topographic point which helps to develop RESTful spider web services inwards Java including JAX-RS which is measure way to develop REST spider web services. Bailiwick of Jersey is ane of the pop implementation of JAX-RS which likewise offers to a greater extent than than specification recommends. Then y'all likewise receive got RESTEasy, RESTlet together with Apache CFX. If y'all similar Scala together with so y'all tin likewise exercise Play framework to develop RESTful spider web services.


Question five : How create y'all configure RESTFul spider web service?

Question vi : How y'all apply safety inwards RESTFul spider web services?

Question seven : Have y'all used securing RESTful APIs alongside HTTP Basic Authentication

Question 8 : How y'all keep session inwards RESTful services?


Question ix : Have y'all used Bailiwick of Jersey API to develop RESTful services inwards Java?
Answer : Bailiwick of Jersey is ane of the most pop framework together with API to develop REST based spider web services inwards Java. Since many organization uses Bailiwick of Jersey they banking company jibe if candidate has used it before or not. It's uncomplicated to answer, tell Yes if y'all receive got genuinely used together with No, if y'all receive got not. In instance of No, y'all should likewise get upwards which framework y'all receive got used for developing RESTful spider web services e.g. Apache CFX, Play or Restlet.


Question 10 : How y'all examine RESTful spider web services?

Question eleven : What is WADL inwards RESTFul?


Question 12 : What create y'all empathize yesteryear payload inwards RESTFul?
Answer : Payload way information which passed within asking torso likewise payload is non asking parameters. So alone y'all tin create payload inwards POST  and non inwards GET together with DELTE method


Question thirteen : Can y'all create payload inwards GET method?
Answer : No, payload tin alone last passed using POST method.


Question fourteen : Can y'all create payload inwards HTTP DELETE?
Answer : This is in ane lawsuit again similar to previous REST interview question, respond is No. You tin alone overstep payload using HTTP POST method.


Question fifteen : How much maximum pay charge y'all could create inwards POST method?
Answer : If y'all cry back difference betwixt GET together with POST request together with so y'all know that dissimilar GET which passes information on URL together with thence express yesteryear maximum URL length, POST has no such limit. So, theoretically y'all tin overstep unlimited information equally payload to POST method but y'all necessitate to accept practical things into concern human relationship e.g. sending POST alongside large payload volition eat to a greater extent than bandwidth, accept to a greater extent than fourth dimension together with acquaint surgical operation challenge to your server.


Question sixteen : What is deviation betwixt SOAP together with RESTFul spider web services?
Answer : There are many deviation betwixt these 2 way of spider web services e.g. SOAP accept to a greater extent than bandwidth because of heavy weight XML based protocol but REST takes less bandwidth because of pop exercise of JSON equally message protocol together with leveraging HTTP method to define action. This likewise way that REST is faster than SOAP based spider web services. You tin derive many differences betwixt SOAP together with RESTful alongside the fact that its HTTP based e.g. REST URLs tin last cached or bookmarked. Here are few to a greater extent than differences betwixt them :

Question 17 : If y'all receive got to develop spider web services which ane y'all volition select SOAP OR RESTful together with why?
Answer : You tin respond this inquiry based upon your sense but the fundamental hither is if y'all know deviation betwixt them than y'all tin respond this inquiry inwards to a greater extent than detail. For example, its slowly to develop RESTful spider web services than SOAP based spider web services but later on comes alongside approximately in-built safety features.


Question xviii :  What framework y'all had used to develop RESTFul services?
Answer : This is genuinely sense based question. If y'all receive got used Bailiwick of Jersey to develop RESTFul spider web services together with so respond equally Bailiwick of Jersey but await approximately follow-up inquiry on Jersey. Similarly if y'all receive got used Apache CFX or Restlet together with so respond them accordingly.


That's all inwards this listing of approximately goodness RESTful spider web service interview questions for Java developers. Though this listing is meant for Java developer, y'all tin exercise this questions to banking company jibe whatever candidate's noesis on REST way spider web services independent of programming linguistic communication because REST doesn't tell that y'all necessitate to implement spider web service inwards Java only. Since it accept payoff of ubiquitous HTTP protocol y'all tin create backed alongside whatever spider web applied scientific discipline stack e.g. Java, .NET or whatever other.

P.S. - If y'all are looking for online preparation to larn how to develop RESTful Web Services inwards Java using Spring framework, I advise y'all joining Eugen Paraschiv's REST alongside Spring course. The class has diverse options depending upon your sense degree together with how much y'all desire to larn e.g. beginner's class, intermediate class, together with master copy class. You tin bring together the ane which suits y'all better, though I advise joining the master copy class if y'all are serious nearly becoming an skillful Java REST developer.
