Example 1

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndAddExp1 
{
    public static void main(String[] args) 
    {
        AtomicInteger number = new AtomicInteger();
        number.getAndAdd(100);
        System.out.println("Updated number is: " + number);
    }
}

Output:

Updated number is: 100

Example 2

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndAddExp2 
{
    public static void main(String[] args) 
    {
        AtomicInteger number = new AtomicInteger(10);
        number.getAndAdd(10);
        System.out.println("Updated number is: " + number);
    }
}

Output:

Updated number is: 20

Example 3

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndAddExp3 
{
    public static void main(String[] args) 
    {
        AtomicInteger number = new AtomicInteger(-100);
        number.getAndAdd(100);
        System.out.println("Updated number is: " + number);
    }
}

Output:

tUpdated number is: 0

Example 4

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndAddExp4 
{
    public static void main(String[] args) 
    {
        AtomicInteger number = new AtomicInteger(-120);
        number.getAndAdd(-100);
        System.out.println("Updated number is:" + number);
    }
}

Output:

Updated number is: -220

Example 5

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndAddExp5 
{
    public static void main(String[] args) 
    {
        AtomicInteger number = new AtomicInteger(20);
        number.getAndAdd(0);
        System.out.println("Updated number is: " + number);
    }
}

Output:

Updated number is: 20
