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：

希望本文所述对大家java程序设计有所帮助。
