LongAdder add() method in Java with Examples

LongAdder class in Java creates a new adder with an initial sum of zero. The Java.LongAdder.add() is an inbuilt method in java that adds the given value.

Syntax:

public void add(long x)

Parameters: The function accepts a single parameter x that specifies the value to be added.

Return value: The method do not returns any value.

Below programs demonstrate the above function:

Program 1:

// Java program to demonstrate
// the LongAdder.add() method

import java.lang.*;
import java.util.concurrent.atomic.LongAdder;

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

        // Initialized with 0
        LongAdder num = new LongAdder();

        // Print the initial value
        System.out.println("Initial value is: "
                           + num);

        // Add 6 to it
        num.add(6);

        // Print the final value
        System.out.println("After addition"
                           + " of 6, value is: "
                           + num);

        // Add 5 to it
        num.add(5);

        // Print the final value
        System.out.println("After addition"
                           + " of 5, value is: "
                           + num);
    }
}

Output:

Initial value is: 0
After addition of 6, value is: 6
After addition of 5, value is: 11

Program 2:

// Java program to demonstrate
// the LongAdder.add() method

import java.lang.*;
import java.util.concurrent.atomic.LongAdder;

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

        // Initialized with 0
        LongAdder num = new LongAdder();

        // Print the initial value
        System.out.println("Initial value is: "
                           + num);

        // Add 10 to it
        num.add(10);

        // Print the final value
        System.out.println("After addition"
                           + " of 10, value is: "
                           + num);

        // Add -5 to it
        num.add(-5);

        // Print the final value
        System.out.println("After addition"
                           + " of -5, value is: "
                           + num);
    }
}

Output:

Initial value is: 0
After addition of 10, value is: 10
After addition of -5, value is: 5
