1、继承Thread类
2、实现Runnable接口
3、两种实现方法之间的关系
4、实例
sleep是属于Thread类的静态函数。
/** * aThread.java * @author cjc */ public class aThread extends Thread { public void run() { for(int i=0;i<10;i++) { System.out.println("The son thread1 is running..."); try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }
/** * bThread.java * @author cjc */ public class bThread implements Runnable { public void run() { for(int i=0;i<10;i++) { System.out.println("The son thread2 is running..."); try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }
/** * ThreadDemo1.java * @author cjc */ public class ThreadDemo1 { public static void main(String[] args) { new aThread().start(); Thread th=new Thread(new bThread()); th.start(); for(int i=0;i<10;i++) { System.out.println("The main thread is running..."); try { Thread.sleep(1000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } } }
