Description

The technique changes the value of the Number entity that appeals to the method to the prehistoric data type that is revisited from the method.

Syntax

Here is a separate method for each primitive data type

byte byteValue()
short shortValue()
int intValue()
long longValue()
float floatValue()
double doubleValue()

Parameters

Here is the detail of parameters:

• All these are default methods and accepts no parameter.

Return Value

• This method returns the primitive data type that is given in the signature.

Example

public class Test { 

   public static void main(String args[]) {
      Integer x = 5;
      
      // Returns byte primitive data type
      System.out.println( x.byteValue() );

      // Returns double primitive data type
      System.out.println(x.doubleValue());

      // Returns long primitive data type
      System.out.println( x.longValue() );      
   }
}

This will produce the following result:

Output
