Java - Convert String To Brusk Example

In concluding a couplet of examples, I receive got taught you lot how to convert String to Integer, Long, Double, Float, Boolean, as well as Byte inwards Java as well as today I volition demo you lot how to convert String to Short inwards Java, but earlier that let's revise what is brusk information type inwards Java. The short is an integral information type similar to the int but it solely takes 2 bytes to shop information every bit compared to iv bytes required yesteryear an int variable. Since it takes solely 2 bytes or sixteen bits to shop data, the make of brusk is also shorter than int. It ranges from -32,768 to 32767 (inclusive) or -2^15 to 2^15 -1. You mightiness live on wondering why upper saltation is 255 and lower saltation is -256 but that's because nosotros receive got included null inwards between.

The short primitive type is also a signed variable, which agency the showtime flake is used to shop sign bit. The publish is also represented inwards two's complement integer.

Now, similar to String to Integer example, at that spot are 3 principal ways to convert a String to brusk primitive value or Short object inwards Java:

1. Using Short.parseShort() method
2. Using Short.valueOf() method
3. Using Short Constructor 

If you lot receive got used parseInt() or Integer.valueOf() method inwards yesteryear as well as then you lot tin sympathise how they behave, both parseShort() as well as Short.valueOf() ship inwards same way. If you lot are novel to Java world, you lot tin farther see The Complete Java Masterclass to larn to a greater extent than about  Java fundamentals similar those. In this article, our focus volition live on on brusk but they are also real useful for converting other information types similar int, char, boolean, long, float as well as double inwards Java.

1. Short.parseShort() Example

This is the actual method which contains parsing logic for converting String to brusk inwards Java. It accepts a String as well as returns a brusk primitive value. The digits must live on inwards decimal format as well as the showtime grapheme tin live on a + or - (minus) sign to betoken positive as well as negative numbers.

Here are some examples of parseShort() method:

short second = Short.parseShort("101"); // returns 101 short second = Short.parseShort("+121"); // returns 121 short second = Short.parseShort("-121"); // returns -121 short second = Short.parseShort("32768"); // throw error 

This method throws an fault if given String is invalid similar contains characters other than a decimal digit as well as positive or negative sign or an out-of-range brusk value.

The method is also overloaded to back upwardly radix like. Short.parseShort(String value, int radix) which tin live on used to convert a binary, octal, or hexadecimal String to equivalent brusk value.

2. Short.valueOf() Example

You tin role this method if you lot necessitate a Short object rather than a brusk value. This method internally uses the parseShort() method for parsing but on top of that, it provides caching. Similar to Integer.valueOf() method this 1 also caches Short values inwards the make -128 to 127.

Here are some examples of Short.valueOf() method:

Short object = Short.valueOf("101"); // returns 101 Short object = Short.valueOf("+121"); // returns 121 Short object = Short.valueOf("-121"); // returns -121 Short object = Short.valueOf("32768"); // throw error

Because of caching, it reduces the publish of the temporary Short object for the oftentimes used range. In short, role this method if you lot necessitate a Short object rather than brusk value to avoid auto-boxing. See Effective Java third Edition yesteryear Joshua Bloch, it's improve to role static manufacturing flora methods similar Short.valueOf() rather than constructor for creating objects. You tin leverage caching to improve surgical physical care for as well as command publish of instances, peculiarly for an immutable class similar Short.

4. Best way to convert String to Short inwards Java?

The preferred method is ever the valueOf() method because it tin cache oftentimes used value as well as relieve retentiveness yesteryear returning immutable objects.

But, if you lot necessitate a brusk primitive value as well as then you lot tin straight role the Short.parseShort() method because it returns a brusk value as well as you lot don't require unboxing.

The Short constructor is fifty-fifty though a uncomplicated approach, it's non recommended because it straight couplet your code alongside a Short constructor.

As suggested inwards Joshua Bloch's classic majority Effective Java, The static manufacturing flora method like valueOf() is improve than the using constructor.  It non solely provides improve surgical physical care for yesteryear caching unremarkably used value but also decouple your code from the Short constructor.

5. Short to String

So far, nosotros receive got looked at the examples of converting a String object to Short object or primitive inwards Java but what nearly the opposite? how create you lot convert a Short object or primitive to String? Well, that's non hard as well as inwards most cases done yesteryear Java automatically.

If you lot remember, the object flat provides a toString() method which is used to convert whatever Object to String as well as wrapper classes similar Short or Integer is no different. In fact, they override toString() method to render their value every bit String.

Btw, you lot necessitate a Short object to convert it to String. So, if you lot receive got a brusk primitive value as well as then merely assign that to a Short object as well as auto-boxing volition automatically convert brusk primitive to a Short object. After that, you lot tin telephone yell upwardly the toString() method.

Here is an illustration of converting brusk to String inwards Java:

Short value = 123; // brusk primitive to Short object String str = value.toString(); // Short object to String

You tin as well as then role this String to impress or exceed it to a method which needs a String value. If you lot are novel to method as well as flat as well as then I advise you lot to start learning Java from The Complete Java Masterclass, 1 of the most comprehensive Java course of teaching out there.

6. Java Program to Convert String to Short

Here is our sample Java computer programme to demonstrate how you lot tin role the parseShort(), valueOf() as well as constructor of java.lang.Short flat to convert a String value inwards Java. You volition also larn the contrary i.e. converting a Short value to String inwards Java.

package tool;  /**  *   * H5N1 uncomplicated Java Program to convert a String to brusk primitive or Short wrapper  * object inwards Java.  */ public class Hello {    public static void main(String[] args) {      // parseShort() Example - String to brusk primitive value     brusk second = Short.parseShort("101");     System.out.println("short primitive value from string: " + s);      // Short.valueOf() Example - String to Short wrapper object     Short sObject = Short.valueOf("151");     System.out.println("Short wrapper value from string: " + sObject);      // Short constructor example     Short value = new Short("251");     System.out.println("Short object from string: " + value);      // Short to String Example using Short.toString()     String str = sObject.toString();     System.out.println("String value from Short object: " + str);      // Out-of-range brusk value volition throw error     brusk outOfRange = Short.parseShort("32768");   }  } Output brusk primitive value from string: 101 Short wrapper value from string: 151 Short object from string: 251 String value from Short object: 151 Exception in thread "main" java.lang.NumberFormatException: Value out of range. Value:"32768" Radix:10 at java.lang.Short.parseShort(Short.java:120) at java.lang.Short.parseShort(Short.java:144) at tool.Hello.main(Hello.java:33)

You tin run into that parseShort() returns a primitive brusk value, valueOf() returns a Short object, as well as you lot tin fifty-fifty role the constructor of java.lang.Short flat to convert a String to brusk inwards Java.

You tin also run into that the contrary conversion e.g. Short to String is, fifty-fifty more, easier because of toString() method of the Short class.

In the example, nosotros receive got also learned that out-of-range brusk values e.g. integer values to a greater extent than than 32767 volition throw java.lang.NumberFormatException inwards Java.

By the way, folks, if you lot desire to larn to a greater extent than nearly the maximum as well as minimum make of unlike information type inwards Java then  The Complete Java Masterclass is a adept course of teaching to start with.

7. Important Points

Now that you lot know how to convert a String to Short inwards Java, let's revise some of the of import points

7.1. There are 3 principal ways to convert a String to brusk inwards Java, parseShort(), valueOf() as well as Short constructor.

7.2. The parseShort() method genuinely parses the given String value as well as render a brusk primitive value.

7.3. Make certain you lot exceed a valid brusk value e.g. if you lot exceed an integer value which is higher than the maximum brusk value i.e. 32767 as well as then it volition throw NumberFormatException every bit shown below:

short value = Short.parseShort("34000");

Exception inwards thread "main" java.lang.NumberFormatException: Value out of range. Value:"34000" Radix:10
at java.lang.Short.parseShort(Short.java:120)
at java.lang.Short.parseShort(Short.java:144)
at tool.Hello.main(Hello.java:14)


7.4. Use Short.parseShort() method if you lot necessitate a brusk boolean value.

7.5. Use Short.valueOf() method if necessitate a Short object every bit this method render a Short object every bit opposed to the brusk primitive value returned yesteryear the parseShort() method.

Even though it leverages the parsing logic of parseShort() method it is preferred because it tin cache oftentimes used Short value to relieve memory.

7.6. Even though you lot tin role the constructor of java.lang.Short flat to convert a String to Short object, avoid that inwards favor of static manufacturing flora method Short.valueOf(). If you lot desire to larn to a greater extent than nearly why static manufacturing flora method is improve than the constructor, banking concern gibe the Item 1 from Effective Java third Edition yesteryear Joshua Bloch.

7.7. The java.lang.Short flat also render methods to convert a decimal brusk value into octal or hexadecimal. It has overloaded parseShort(String value, int radix) as well as valueOf(String value, int radix) which takes a radix to convert given String to Short inwards other publish systems.

7.8. Short is a wrapper flat for brusk primitive value, which takes 2 bytes of 16-bit to shop numeric integral value. The minimum brusk value is -32768 as well as the maximum value is 32767.


That's all nearly how to convert String to Short inwards Java. In a nutshell, if you lot necessitate a brusk primitive value, merely role Short.parseShort() method as well as if you lot necessitate a Short wrapper object, prefer Short.valueOf() method. Though, live on careful alongside the range, passing an out-of-range integer value to convert brusk may effect inwards NumberFormatException.
