Java - Byte Class longValue() Method

Byte class longValue() method: Here, we are going to learn about the longValue() method of Byte class with its syntax and example. By Preeti Jain Last updated : March 18, 2024

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.

Syntax

public long longValue();

Parameter2

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.

Example

// 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());
    }
}

Output

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