The java.lang.Byte.doubleValue() method is used to return the value of this Byte as a double after a widening primitive conversion.

Syntax

public double doubleValue()

Parameters

No parameter is required.

Return Value

Returns the numeric value represented by this object after conversion to type double.

Exception

NA.

Example:

In the below example, the java.lang.Byte.doubleValue() method is used to return a Byte object after conversion to type double.

import java.lang.*;

public class MyClass {
  public static void main(String[] args) {
    
    //creating Byte objects
    Byte val1 = new Byte("25");
    Byte val2 = new Byte("-25");

    //printing doubleValue of the Byte objects
    System.out.println("doubleValue of the val1 is: " + val1.doubleValue()); 
    System.out.println("doubleValue of the val2 is: " + val2.doubleValue());   
  }
}

The output of the above code will be:

doubleValue of the val1 is: 25.0
doubleValue of the val2 is: -25.0
