Thread

问题：编写一个能提现多线程的例子？假设有t1,t2两个线程，如何保证t2线程在t1线程执行完后再执行？

package cn.changb.thread;

public class MyThread implements Runnable {

    @Override
    public void run() {
        // TODO Auto-generated method stub
        for (int i = 0; i < 100; i++) {
            System.out.println(Thread.currentThread().getName() + "-" + i);
        }
    }

}

package cn.changb.thread;

public class ThreadTest {

    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub
        Thread thread = new Thread(new MyThread());
        thread.start();
        thread.join();// 在上述线程执行结束后再执行后续线程的内容
        new Thread(new MyThread()).start();
    }

}
