[Hello_ood]

https://blog.csdn.net/hejingyuan6/article/details/47053409 这个博客的第一个例子貌似是有问题的，我做了一个实验，多试几次 总数就能达到 10000，下方留了截图

public class MultipThreadShareData2 {
    public static void main(String[] args) throws InterruptedException {
        AtomicInteger atomicInteger = new AtomicInteger(0);
        ShareData11 data1 = new ShareData11(atomicInteger);
        Thread t = new Thread(data1);
        Thread t2 = new Thread(data1);
        Thread t3 = new Thread(data1);
        Thread t4 = new Thread(data1);
        t.start();
        t2.start();
        t3.start();
        t4.start();

        TimeUnit.SECONDS.sleep(2);

        System.out.println(data1.atomicInteger.get());
    }
}

class ShareData11 implements Runnable{
    AtomicInteger atomicInteger;
    public ShareData11(AtomicInteger atomicInteger) {
        this.atomicInteger = atomicInteger;
    }
    private int count = 1;
    @Override
    public void run() {
        while(count < 10000){
            atomicInteger.incrementAndGet();
            System.out.println("线程:  " + Thread.currentThread().getName() + "  " + (count++));
        }
    }
}
