public class AtomicUpdaterTest {
    public static void main(String[] args) {


        AtomicIntegerFieldUpdater<Person> age = AtomicIntegerFieldUpdater.newUpdater(Person.class, "age");

        Person person = new Person();

        for (int i = 0; i < 10; i++) {

            new Thread(() -> System.out.println( age.getAndIncrement(person))).start();

        }


    }
    static class Person {
        volatile int age;
    }

}
