AtomicInteger represents an int value that may be updated AtomicInteger is present in the java.util.concurrent.atomic package.
The incrementAndGet method of the AtomicInteger will atomically increment the current value by 1 and returns the updated value of the AtomicInteger object.
public final int incrementAndGet()
This method doesn’t take any argument.
This method returns the incremented value as an integer.
The code below demonstrates how to use the incrementAndGet method:
import java.util.concurrent.atomic.AtomicInteger;class IncrementAndGet{public static void main(String[] args) {AtomicInteger atomicInteger = new AtomicInteger(10);System.out.println("The value in the atomicInteger object is " + atomicInteger.get());System.out.println("\nCalling atomicInteger.incrementAndGet()");int val = atomicInteger.incrementAndGet();System.out.println("The new Value is : " + val);}}
Line 1: We have imported the AtomicInteger class.
Line 2: Definition of class IncrementAndGet that shows the implementation of incrementAndGet method.
Line 4: Created a new object for the AtomicInteger class with the name atomicInteger and with the value 10.
Line 9: Called the incrementAndGet method. This method will increment the current value(10) by 1 and returns the new value(11).
