Double class byteValue() method

  • byteValue() method is available in java.lang package.
  • byteValue() method is used to return the value denoted by this Double object converted to type byte (by casting).
  • byteValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • byteValue() method does not throw an exception at the time of conversion from double to byte.


    public byte byteValue();


  • It does not accept any parameter.

Return value:

The return type of this method is byte, it returns a converted (from type double to byte) value represented by this Double object.


// Java program to demonstrate the example 
// of byteValue() method of Double class

public class ByteValueOfDoubleClass {
    public static void main(String[] args) {
        // Variables initialization
        double d1 = 18.20;
        double d2 = 19.20;

        // It returns double value denoted by this Double do1 object
        // and converted to a byte by calling do1.byteValue()
        Double do1 = new Double(d1);

        // Display do1 result
        System.out.println("do1.byteValue(): " + do1.byteValue());

        // It returns double value denoted by this Double do2 object
        // and converted to a byte by calling do2.byteValue()
        Double do2 = new Double(d2);

        // Display do2 result
        System.out.println("do2.byteValue(): " + do2.byteValue());



do1.byteValue(): 18
do2.byteValue(): 19
