Java AtomicInteger getAndIncrement() method

Last Updated : 17 Mar 2025

The getAndIncrement() method of Java AtomicInteger class gets the value first and increment it by one.

Syntax

Return

This method returns the previous value.

Example 1

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndIncrementExp1 
{
    public static void main(String[] args) 
    {
        AtomicInteger value = new AtomicInteger();
        int value1 = value.getAndIncrement();
        System.out.println("the updated number: "+ value);
        System.out.println("the previous number: "+ value1);
    }
}

Output:

the updated number: 1
the previous number: 0

Example 2

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndIncrementExp2 
{
    public static void main(String[] args) 
    {
        AtomicInteger value = new AtomicInteger(10);
        int value1 = value.getAndIncrement();
        System.out.println("the updated number: "+value);
        System.out.println("the previous number: "+value1);
    }
}

Output:

the updated number: 11
the previous number: 10

Example 3

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndIncrementExp3 
{
    public static void main(String[] args) 
    {
        AtomicInteger value = new AtomicInteger(1);
        int value1 = value.getAndIncrement();
        System.out.println("the updated number: "+value);
        System.out.println("the previous number: "+value1);
    }
}

Output:

the updated number: 2
the previous number: 1

Example 4

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndIncrementExp4
{
    public static void main(String[] args) 
    {
        AtomicInteger value = new AtomicInteger(-1);
        int value1 = value.getAndIncrement();
        System.out.println("the updated number: " +value);
        System.out.println("the previous number: " +value1);
    }
}

Output:

the updated number: 0
the previous number: -1

Example 5

import java.util.concurrent.atomic.AtomicInteger;
public class AtomicIntegerGetAndIncrementExp5 
{
    public static void main(String[] args) 
    {
        AtomicInteger value = new AtomicInteger(-4);
        int value1 = value.getAndIncrement();
        System.out.println("the updated number: "+value);
        System.out.println("the previous number: "+value1);
    }
}

Output:

the updated number: -3
the previous number: -4
