Byte longValue() method in Java with examples

Last Updated : 11 Jul, 2025
The longValue() method of Byte class is a built in method in Java which is used to return the value of this Byte object as long. Syntax 
ByteObject.longValue()
Return Value: It return the value of ByteObject as long. Below is the implementation of longValue() method in Java: Example 1: Java 
// Java code to demonstrate
// Byte longValue() method

class GFG {
    public static void main(String[] args)
    {

        // byte value
        byte a = 17;

        // wrapping the byte value
        // in the wrapper class Byte
        Byte b = new Byte(a);

        // longValue of the Byte Object
        long output = b.longValue();

        // printing the output
        System.out.println("Long value of "
                           + b + " is : " + output);
    }
}
Output: 
Long value of 17 is : 17
Example 2: Java 
// Java code to demonstrate
// Byte longValue() method

class GFG {
    public static void main(String[] args)
    {

        String value = "17";

        // wrapping the byte value
        // in the wrapper class Byte
        Byte b = new Byte(value);

        // longValue of the Byte Object
        long output = b.longValue();

        // printing the output
        System.out.println("Long value of "
                           + b + " is : " + output);
    }
}
Output: 
Long value of 17 is : 17
