我有以下代码:

public class ThreadTest implements Runnable {
    public int ThrCount    = 0;

    public void ThrCountIncr() {
        while (true) {
            ThrCount++;
            System.out.println(ThrCount);
            try {
                Thread.currentThread().sleep(500);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }

    public void run() {
        while (true) {
            if (ThrCount > 10) {
                System.out.println(ThrCount + "\n Thread finished");
                System.exit(1);
            }
            try {
                Thread.currentThread().sleep(100);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}

但是,当我从中删除此行时run,它将停止工作:

Thread.currentThread().sleep(100);

首先,我启动线程,然后我使用 …
