Example

The following example shows the usage of lang.Byte.doubleValue() method.

package com.tutorialspoint;

import java.lang.*;

public class ByteDemo {

   public static void main(String[] args) {

      // create 2 Byte objects b1, b2
      Byte b1, b2;

      // create 2 double primitives d1, d2
      double d1, d2;

      // assign values to b1, b2
      b1 = new Byte("100");
      b2 = new Byte("-10");

      // assign double values of b1, b2 to d1, d2
      d1 = b1.doubleValue();
      d2 = b2.doubleValue();

      String str1 = "double value of Byte " + b1 + " is " + d1;
      String str2 = "double value of Byte " + b2 + " is " + d2;

      // print d1, d2 values
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

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

double value of Byte 100 is 100.0
double value of Byte -10 is -10.0
