Java - Short ValueOf() Method

The Java Short ValueOf() method retrieves a Short object holding the value given by the specified String; or short value; or the specified String when parsed with the radix given by the second argument (depending on the type of value assigned).

This method has three polymorphic variants. They are −

  • valueOf(short s) − This method retrieves a Short instance representing the specified short value s.

  • valueOf(string s) − This method retrieves the Short object equivalent to the string value provided.

  • valueOf(String s, int radix): ) − This method retrieves the Short object which is equal to the value of new Short(Short.parseShort(s, radix))

Syntax

Following is the syntax for Java Short ValueOf() method −

public static Short valueOf(short s) // first syntax
or,
public static Short valueOf(String s) throws NumberFormatException // second syntax
or,
public static Short valueOf(String s, int radix) throws NumberFormatException // third syntax

Parameters

  • s − This is the short value. // first syntax

  • s − This is the string to be parsed. // second and third syntax

  • radix − This is the radix to be used in interpreting s // third syntax

Return Value

This method returns −

  • a Short instance representing s. // first syntax

  • a Short object holding the value represented by the string argument. // second syntax

  • a Short object holding the value represented by the string argument in the specified radix. // third argument

Example

In the example given below a short variable 'shortNum' is created and a value is assigned to it. Then it returns the Short instance representing given short value using Java Short valueOf(short s) method of Short class −

import java.lang.*;
public class ShortDemo {
   public static void main(String[] args) {
      short shortNum = 100;  
      
      // returns Short instance representing given short value
      Short ShortValue = Short.valueOf(shortNum);
      
      // displays the short object value
      System.out.println("Short object representing the specified short value = " + ShortValue);
   }
}

Output

Let us compile and run the above program, this will produce the following result −

Short object representing the specified short value = 100

Example

Following is an example of the Java Short ValueOf() method −

import java.lang.*;
public class ShortDemo {
   public static void main(String[] args) {
      short shortNum = 100;
      String str = "600"; 
      
      // returns Short object representing given short value
      Short ShortValue = Short.valueOf(shortNum);
      
      // displays the short object value
      System.out.println("Short object representing the specified short value = " + ShortValue);
      
      // returns a Short object holding the value given by the specified String
      ShortValue = Short.valueOf(str);   
      
      // displays the short object value
      System.out.println("Short object holding the value given by the specified String = " + ShortValue);
   }
}

Output

Following is an output of the above code −

Short object representing the specified short value = 100
Short object holding the value given by the specified String = 600

Example

In the example that follows a Short object holding the value from the specified string according to radix is returned using valueOf(String s, int radix) method −

import java.lang.*;
public class ShortDemo {
   public static void main(String[] args) {
      short shortNum = 100;
      String str = "1000";   
      
      // returns Short object representing given short value
      Short ShortValue = Short.valueOf(shortNum);    
      
      // displays the short object value
      System.out.println("Short object representing the specified short value = " + ShortValue);
      
      // returns a Short object holding the value given by the specified String
      ShortValue = Short.valueOf(str);      
      
      // displays the short object value
      System.out.println("Short object holding the value given by the specified String = " + ShortValue);  
      /* returns a Short object holding the value from the specified String according to radix. */
      ShortValue = Short.valueOf(str , 2) ;
      
      // displays the short object value
      System.out.println("Short object value for specified String with radix 2 = " + ShortValue);
      
      // returns a Short object holding the value for string to radix   
      ShortValue = Short.valueOf("15" , 8) ;
      
      // displays the short object value
      System.out.println("Short object value String 15 with radix 8 = " + ShortValue);
   }
}

Output

Output of the above code is as follows −

Short object representing the specified short value = 100
Short object holding the value given by the specified String = 1000
Short object value for specified String with radix 2 = 8
Short object value String 15 with radix 8 = 13

Example

In the following example the value assigned to the string variable ‘value3’ does not contain a parsable number and hence it throws exception error −

import java.lang.Double;
public class ShortDemo {
   public static void main(String[] args) {
      String value1 = "9089";
      String value2 = "-2567";
      String value3 = "Deepak@21";
      
      // returning the equivalent short object of the string value
      System.out.println("The Short object Value is = " + Short.valueOf(value1));
      System.out.println("The Short object Value is = " + Short.valueOf(value2));
      System.out.println("The Short object Value is = " + Short.valueOf(value3));
   }
}

NumberFormatException

While executing the above code we get the following output −

The Short object Value is = 9089
The Short object Value is = -2567
