正确代码详解：
public class AtomicStampedReferenceTest {
private final static AtomicStampedReference<Integer> atomicStampedReference = new AtomicStampedReference<>(100, 1);
public static void main(String[] args) {
new Thread(() -> {
int stamp = atomicStampedReference.getStamp();
try {
TimeUnit.SECONDS.sleep(1);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println(Thread.currentThread().getName() + " 第1次版本号:" + stamp);
boolean c = atomicStampedReference.compareAndSet(100, 101, atomicStampedReference.getStamp(), atomicStampedReference.getStamp() + 1);
System.out.println(Thread.currentThread().getName() + " 第2次版本号:" + atomicStampedReference.getStamp()+" boolean:"+c);
boolean b = atomicStampedReference.compareAndSet(101, 100, atomicStampedReference.getStamp(), atomicStampedReference.getStamp() + 1);
System.out.println(Thread.currentThread().getName() + " 第2次版本号:" + atomicStampedReference.getStamp()+" boolean:"+b);
}).start();
new Thread(() -> {
int stamp = atomicStampedReference.getStamp();
try {
TimeUnit.SECONDS.sleep(3);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println(Thread.currentThread().getName() + " 第1次版本号:" + stamp);
boolean b = atomicStampedReference.compareAndSet(100, 2021, stamp, stamp + 1);
System.out.println(Thread.currentThread().getName() + " 获取到的值：" + atomicStampedReference.getReference() + " boolean:"+b);
}).start();
}
}
