本文实例讲述了Java实现在不同线程中运行的代码。分享给大家供大家参考，具体如下：

start()方法开始为一个线程分配CPU时间，这导致对run()方法的调用。

代码1

package Threads;/** * Created by Frank */public class ThreadsDemo1 extends Thread { private String msg; private int count; public ThreadsDemo1(final String msg, int n) {  this.msg = msg;  count = n;  setName(msg + " runner Thread"); } public void run() {  while (count-- > 0) {   System.out.println(msg);   try {    Thread.sleep(100);   } catch (InterruptedException e) {    return;   }  }  System.out.println(msg + " all done."); } public static void main(String[] args) {  new ThreadsDemo1("Hello from X", 10).start();  new ThreadsDemo1("Hello from Y", 15).start(); }}

代码2：

package Threads;/** * Created by Frank */public class ThreadsDemo2 implements Runnable { private String msg; private Thread t; private int count; public static void main(String[] args) {  new ThreadsDemo2("Hello from X", 10);  new ThreadsDemo2("Hello from Y", 15); } public ThreadsDemo2(String m, int n) {  this.msg = m;  count = n;  t = new Thread(this);  t.setName(msg + "runner Thread");  t.start(); } public void run() {  while (count-- > 0) {   System.out.println(msg);   try {    Thread.sleep(100);   } catch (InterruptedException e) {    return;   }  }  System.out.println(msg + " all done."); }}

代码3：

package Threads;/** * Created by Frank */public class ThreadsDemo3 { private int count; public static void main(String[] args) {  new ThreadsDemo3("Hello from X", 10);  new ThreadsDemo3("Hello from Y", 15); } public ThreadsDemo3(final String msg, int n) {  this.count = n;  Thread t = new Thread(new Runnable() {   public void run() {    while (count-- > 0) {     System.out.println(msg);     try {      Thread.sleep(100);     } catch (InterruptedException e) {      return;     }    }    System.out.println(msg + " all done.");   }  });  t.setName(msg + " runner Thread");  t.start(); }}

eclipse运行结果如下：
