Java AtomicInteger addAndGet() method

The addAndGet() method of Java AtomicInteger class atomically adds the given value to the current value.

Syntax

Parameters

delta - It is the value to add

Return

It returns the updated value.

Example 1

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerAddAndGetExp1
{
    public static void main(String[] args) 
    {
        System.out.println("when initial value is 0: " + addAndGet());
    }
    public static int addAndGet() 
    {
        AtomicInteger number= new AtomicInteger();
        int number1=number.addAndGet(2);
        return (number1);
    }
}

Test it Now

Output:

when initial value is 0: 2

Example 2

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerAddAndGetExp2
{
    public static void main(String[] args)
    {
        System.out.println("when initial value is 100: "+addAndGet());
    }
    public static int addAndGet() 
    {
        AtomicInteger number = new AtomicInteger(100);
        int number1 = number.addAndGet(2);
        return (number1);
    }
}

Test it Now

Output:

when initial value is 100: 102

Example 3

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerAddAndGetExp3
{
    public static void main(String[] args) 
    {
        System.out.println("when initial value is 100: " + addAndGet());
    }
    public static int addAndGet() 
    {
        AtomicInteger number = new AtomicInteger(100);
        int number1 = number.addAndGet(-200);
        return (number1);
    }
}

Test it Now

Output:

when initial value is 100: -100

Example 4

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerAddAndGetExp4
{  
    public static void main(String[] args) 
    {  
        System.out.println("when initial value is -100: " + addAndGet());  
    }  
    public static int addAndGet() 
    {  
        AtomicInteger number= new AtomicInteger(-100);  
        int number1=number.addAndGet(6);  
        return (number1);  
    }  
}

Test it Now

Output:

when initial value is -100: -94

Example 5

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerAddAndGetExp5
{
    public static void main(String[] args) 
    {
        System.out.println("when initial value is -100: "+addAndGet());
    }
    public static int addAndGet() 
    {
        AtomicInteger number= new AtomicInteger(-100);
        int number1=number.addAndGet(-100);
        return (number1);
    }
