Byte doubleValue() method in Java with examples

Last Updated : 08 Oct, 2018

The doubleValue() method of Byte class is a built in method in Java which is used to return the value of this Byte object as double.

Syntax

ByteObject.doubleValue()

Return type: It returns the value of ByteObject as double.

Below is the implementation of doubleValue() method in Java:

Example 1:

// Java code to demonstrate 
// Byte doubleValue() method 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        // byte value 
        byte a = 17; 
  
        // wrapping the byte value 
        // in the wrapper class Byte 
        Byte b = new Byte(a); 
  
        // doubleValue of the Byte Object 
        double output = b.doubleValue(); 
  
        // printing the output 
        System.out.println("Double value of "
                           + a + " is : " + output); 
    } 
} 

Output:

Double value of 17 is : 17.0

Example 2:

// Java code to demonstrate 
// Byte doubleValue() method 
  
class GFG { 
    public static void main(String[] args) 
    { 
  
        String value = "17"; 
  
        // wrapping the byte value 
        // in the wrapper class Byte 
        Byte b = new Byte(value); 
  
        // doubleValue of the Byte Object 
        double output = b.doubleValue(); 
  
        // printing the output 
        System.out.println("Double value of "
                           + b + " is : " + output); 
    } 
} 

Output:

Double value of 17 is : 17.0
