一、Runnable

　　Runnable為一個之包含一個run方法的接口

 1 public class MyRunnable implements Runnable{
 2     @Override                                    //表示：預示重寫方法
 3     public void run() {                            //實現接口run方法
 4         System.out.println("實現Runnable的線程0.0\t"+Thread.currentThread().getName());
 5         
 6
 
     }
 7     
 8     public static void main(String[] args) {
 9         //創建Runnable對象
10         MyRunnable run = new MyRunnable();
11         //以對象run為參數創建Thread對象
12         Thread thr1 = new Thread(run,"線程-1");
13         Thread thr2 = new Thread(run,"線程-2");
14         Thread thr3 = new Thread(run,"線程-3");
 
15         Thread thr4 = new Thread(run,"線程-4");
16         Thread thr5 = new Thread(run,"線程-5");
17         //啟動線程
18         thr1.start();
19         thr2.start();
20         thr3.start();
21         thr4.start();
22         thr5.start();
23     }
24 
25 
26 }

運行結果為

二、Thread

　　Thread為一個實現了Runnable的類

 1 public class Threads extends Thread{
 2     //構造方法
 3     String name;
 4     Threads(String name){
 5         this.name = name;
 6     }
 7     //重寫run方法
 8     public void run(){
 9         System.out.println("實現Runnable的線程0.0\t"+Thread.currentThread().getName());
10     }
11 
12     public static void main(String[] args) {
13         //創建Treads對象
14         Threads thr1 = new Threads("線程-1");
15         Threads thr2 = new Threads("線程-2");
16         Threads thr3 = new Threads("線程-3");
17         Threads thr4 = new Threads("線程-4");
18         Threads thr5 = new Threads("線程-5");
19         //啟動線程
20         thr1.start();
21         thr2.start();
22         thr3.start();
23         thr4.start();
24         thr5.start();
25 
26     }
27 
28 }

運行結果

JAVA多線程Thread與Runnable
