Java Byte longValue() method

Last Updated : 17 Mar 2025

The longValue() method of Java Byte class returns a long value for this Byte after a widening primitive conversion.

Syntax:

Parameters:

Specified by

This method is specified by longValue in class Number

Return Value

This method returns the numeric value of this object after conversion to type long.

Example 1

Example

public class Main {
    public static void main(String[] args) {
        Byte b1=98;
        Byte b2=102;
        //returns the numeric value of this object after conversion to type long.
        Long val=b1.longValue();
        System.out.println("1. Long value : "+val);
        System.out.println("2. Long value : "+b2.intValue());
    }
}

Compile and Run

Output:

Long value : 98
Long value : 102

Example 2

Example

public class Main {
    public static void main(String[] args) {
        Byte byte1=26;
        //converting the byte value to Long
        Long val1=byte1.longValue();
        Byte byte2=45;
        //converting the byte value to Long
        Long val2=byte2.longValue();
        //calling Long class methods
        System.out.print("Maximum number between "+val1+" and "+val2+" : ");
        System.out.println(Long.max(val1,val2));
        System.out.print("Minimum number between "+val1+" and "+val2+" : ");
        System.out.println(Long.min(val1,val2));
    }
}

Compile and Run

Output:

Maximum number between 26 and 45 : 45
Minimum number between 26 and 45 : 26

Example 3

Example

public class Main {
    public static void main(String[] args) {
        Byte byte1=20;
        //converting the byte value to long
        Long val1=byte1.longValue();
        Byte byte2=-9;
        Long val2=byte2.longValue();
        //calling long class methods
        System.out.println("Sum : ");
        System.out.print(val1+" + ("+val2+") : ");
        System.out.println(Long.sum(val1,val2));
    }
}

Compile and Run

Output:

Sum : 
20 + (-9) : 11
