Java AtomicLong incrementAndGet() Method

The incrementAndGet() method of Java AtomicLong class increments current value by 1 and return updated value. This method is equivalent to AtomicLong addAndGet(1) method.

Syntax

Returns

the updated value

Example 1

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongIncrementAndGetExample1 {
		public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong();
		//Increments the Initialized value
		Long result = atomiclong.incrementAndGet();
		//Prints the updated value
		System.out.println("Updated Value : " + result);
	}
}

Test it Now

Output:

Updated Value : 1

Example 2

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongIncrementAndGetExample2 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(10);
		//Increments the Initialized value
		Long result = atomiclong.incrementAndGet();
		//Prints the updated value
		System.out.println("Updated Value : " + result);
	}
}

Test it Now

Output:

Updated Value : 11

Example 3

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongIncrementAndGetExample3 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(-20);
		//Increments the Initialized value
		Long result = atomiclong.incrementAndGet();
		//Prints the updated value
		System.out.println("Updated Value : " + result);
	}
