多線程---模擬叫號看病

//實現Runnable，編寫VIP病人看病線程
public class MyRunnable implements Runnable{
    private int num ; 
    public void run() {
        while(true) {
            if(num == 10) {
                break;
            }
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            System.out.println(Thread.currentThread().getName()+(num+1)+"號病人正在看病！");
            num++;
        }
    }
}

//測試類，編寫普通病人看病線程
public class Test {
    public static void main(String[] args) {
        Thread.currentThread().setName("普通號：");
        MyRunnable vip = new MyRunnable();
        Thread thread = new Thread(vip,"特需號：");
        thread.start();
        int num = 0 ;
        while(true) {
            if(num == 10) {
                try {
                    thread.join();//中止普通病人的看病線程，由VIP病人線程先執行完
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            if(num>=50) {
                break;
            }
            try {
                Thread.sleep(500);
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            System.out.println(Thread.currentThread().getName()+(num+1)+"號正在看病！");
            num++;
        }
    }
}
