Long class byteValue() method: Here, we are going to learn about the byteValue() method of Long class with its syntax and example. By Preeti Jain Last updated : March 19, 2024

Long class byteValue() method

byteValue() method is available in java.lang package.
byteValue() method is used to return the value denoted by this Long object converted to type byte (by casting).
byteValue() method is a non-static method, it is accessible with 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 Long to byte.

Syntax

public byte byteValue();

Parameters

It does not accept any parameter.

Return Value

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

Example

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

public class ByteValueOfLongClass {
    public static void main(String[] args) {
        // Variables initialization
        long l1 = 10;
        long l2 = 20;

        // It returns long value denoted by this Long ob1 object
        // and converted to a byte by calling ob1.byteValue()
        Long ob1 = new Long(l1);

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

        // It returns long value denoted by this Long ob2 object
        // and converted to a byte by calling ob2.byteValue()
        Long ob2 = new Long(l2);

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

Output

ob1.byteValue(): 10
ob2.byteValue(): 20
