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();
     }

 }
