请教怎样进行多线程调试。

Question

如下所示，我将断点打在//断点1 这个位置，但是调试的时候run方法进不去，但是程序始终处于运行状态，请教大家，怎样进行多线程程序的调试？

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

class MyThread extends Thread{
private String taskID;

public MyThread(String taskID){
    this.taskID=taskID;
}

public void run(){    // 断点1
    for (int i = 0; i < 3; i++) {
        try {
            Thread.sleep(500);// 为了测试出效果，让每次任务执行都需要一定时间   
            System.out.println(taskID+"-"+i+"睡眠中");
        } catch (Exception e) {
            e.printStackTrace();
        }
            System.out.println("第 "+taskID+" 次任务的第 "+i+" 次执行");
    }
}

}

public class ExecutorTest {
public static void main(String[] args) {
// 创建可以容纳3个线程的线程池

ExecutorService fixedThreadPool = Executors.newFixedThreadPool(3);

MyThread myThread1=new MyThread("0");
fixedThreadPool.execute(myThread1);
MyThread myThread2=new MyThread("1");
fixedThreadPool.execute(myThread2);
MyThread myThread3=new MyThread("2");
fixedThreadPool.execute(myThread3);
fixedThreadPool.shutdown();
while(true){
if(fixedThreadPool.isTerminated()){
System.out.println("所有计算完毕！");
break;
}
}
}
}
