Byte class longValue() method

  • longValue() method is available in java.lang package.
  • longValue() method is used to return the value denoted by this Byte object converted to type long (by casting).
  • longValue() 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.
  • longValue() method does not throw an exception at the time of conversion from Byte to long.


    public long longValue();


  • It does not accept any parameter.

Return value:

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


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

public class LongValueOfByteClass {
    public static void main(String[] args) {
        // Variables initialization
        byte b1 = 20;
        byte b2 = 30;

        // It returns byte value denoted by this Byte ob1 object
        // and converted to a long by calling ob1.longValue()
        Byte ob1 = new Byte(b1);

        // Display ob1 result
        System.out.println("ob1.longValue(): " + ob1.longValue());

        // It returns byte value denoted by this Byte ob2 object
        // and converted to a long by calling ob2.longValue()
        Byte ob2 = new Byte(b2);

        // Display ob2 result
        System.out.println("ob2.longValue(): " + ob2.longValue());


ob1.longValue(): 20
ob2.longValue(): 30
