Byte class byteValue() method

  • byteValue() method is available in java.lang package.
  • byteValue() method is used to return the value denoted by this Byte 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 Byte 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 Byte to byte) value represented by this Byte object.


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

public class ByteValueOfByteClass {
    public static void main(String[] args) {
        // Variables initialization
        byte b1 = 10;
        byte b2 = 20;

        // It returns byte value denoted by this Byte value1 object
        // and converted to a byte by calling value1.byteValue()
        Byte value1 = new Byte(b1);

        // Display value1 result
        System.out.println("value1.byteValue(): " + value1.byteValue());

        // It returns byte value denoted by this Byte value2 object
        // and converted to a byte by calling value2.byteValue()
        Byte value2 = new Byte(b2);

        // Display value2 result
        System.out.println("value2.byteValue(): " + value2.byteValue());



value1.byteValue(): 10
value2.byteValue(): 20
