How do I use AtomicInteger in Java?

AtomicInteger is a class in Java that provides an integer value that may be updated atomically. You can use it for thread-safe operations.

Can you show me a simple example of how to increment an AtomicInteger?

Sure! Here's a simple example:

import java.util.concurrent.atomic.AtomicInteger;

public class Example {
    public static void main(String[] args) {
        AtomicInteger atomicInt = new AtomicInteger(0);
        int incrementedValue = atomicInt.incrementAndGet();
        System.out.println("Incremented Value: " + incrementedValue);
    }
}

What happens if multiple threads try to increment it at the same time?

AtomicInteger ensures that the increment operation is atomic, meaning it will handle concurrent increments correctly without any data corruption.

Are there other atomic classes in Java?

Yes, Java provides several atomic classes like AtomicLong, AtomicBoolean, and AtomicReference, which serve similar purposes for different data types.
