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
