使用Runnable接口创建线程-3

实现Runnable接口的类必须使用Thread类的实例才能创建线程。通过Runnable接口创建线程分为两步：

1. 将实现Runnable接口的类实例化。

2. 建立一个Thread对象，并将第一步实例化后的对象作为参数传入Thread类的构造方法。

最后通过Thread类的start方法建立线程。

 package com.fly.example;

 public class MyRunnableThree implements Runnable {

     @Override
       public void run()
     {
         System.out.println(Thread.currentThread().getName());
     }
     public static void main(String[] args)
     {
         MyRunnableThree t1 = new MyRunnableThree();
         MyRunnableThree t2 = new MyRunnableThree();
         MyRunnableThree t3 = new MyRunnableThree();
         Thread thread1 = new Thread(t1, "MyThread1");
         Thread thread2 = new Thread(t2);
         Thread thread3 = new Thread(t3);
         thread2.setName("MyThread2");
         thread1.start();
         thread2.start();
         thread3.start();

     }

 }

运行结果如下：
MyThread1
MyThread2
Thread-1
