JAVA多线程Thread与Runnable

一、Runnable

　　Runnable为一个之包含一个run方法的接口

 public class MyRunnable implements Runnable{
     @Override                                    //表示：预示重写方法
     public void run() {                            //实现接口run方法
         System.out.println("实现Runnable的线程0.0\t"+Thread.currentThread().getName());

     }

     public static void main(String[] args) {
         //创建Runnable对象
         MyRunnable run = new MyRunnable();
         //以对象run为参数创建Thread对象
         Thread thr1 = new Thread(run,"线程-1");
         Thread thr2 = new Thread(run,"线程-2");
         Thread thr3 = new Thread(run,"线程-3");
         Thread thr4 = new Thread(run,"线程-4");
         Thread thr5 = new Thread(run,"线程-5");
         //启动线程
         thr1.start();
         thr2.start();
         thr3.start();
         thr4.start();
         thr5.start();
     }

 }

运行结果为

二、Thread

　　Thread为一个实现了Runnable的类

 public class Threads extends Thread{
     //构造方法
     String name;
     Threads(String name){
         this.name = name;
     }
     //重写run方法
     public void run(){
         System.out.println("实现Runnable的线程0.0\t"+Thread.currentThread().getName());
     }

     public static void main(String[] args) {
         //创建Treads对象
         Threads thr1 = new Threads("线程-1");
         Threads thr2 = new Threads("线程-2");
         Threads thr3 = new Threads("线程-3");
         Threads thr4 = new Threads("线程-4");
         Threads thr5 = new Threads("线程-5");
         //启动线程
         thr1.start();
         thr2.start();
         thr3.start();
         thr4.start();
         thr5.start();

     }

 }
