public class Example02 { public static void main(String[] args) { MyThread myThread=new MyThread(); myThread.start(); while(true){ System.out.println("main()方法在运行"); } }}class MyThread extends Thread{ public void run(){ while(true){ System.out.println("MyThread类的run()方法在运行"); } }}
实现Runnable接口创建多线程
public class Example03 { public static void main(String[] args) { MyThread myThread=new MyThread(); Thread thread= new Thread(myThread); thread.start(); while(true){ System.out.println("main()方法在运行"); } }}class MyThread implements Runnable{ public void run(){ while(true){ System.out.println("MyThread类的run()方法在运行"); } }}
两种实现多线程方式的对比分析
通过继承Thread类的方式创建多线程
public class Example04 { public static void main(String[] args) { new TicketWindow().start(); new TicketWindow().start(); new TicketWindow().start(); new TicketWindow().start(); }}class TicketWindow extends Thread{ private int tickets=100; public void run(){ while(true){ if(tickets>0){ Thread th=Thread.currentThread(); String th_name = th.getName(); System.out.println(th_name+"正在发售第"+tickets--+"张票"); } } }}
通过实现Runnable接口的方式创建多线程
public class Example05 { public static void main(String[] args) { TicketWindow tw =new TicketWindow(); new Thread(tw,"窗口1").start(); new Thread(tw,"窗口2").start(); new Thread(tw,"窗口3").start(); new Thread(tw,"窗口4").start(); }}class TicketWindow implements Runnable{ private int tickets=100; public void run(){ while(true){ if(tickets>0){ Thread th=Thread.currentThread(); String th_name = th.getName(); System.out.println(th_name+"正在发售第"+tickets--+"张票"); } } }}
