多线程的同步

多线程的同步

多线程同步可以使用synchronized关键字实现 当synchronized关键字修饰一个方法时，就叫同步方法 当synchronized方法执行完或发生异常，会自动释放锁

package com.cs; public class Test { public static void main(String[] args) { DinnerWindows d = new DinnerWindows(); d.setName("一号窗口："); DinnerWindows w = new DinnerWindows(); w.setName("二号窗口："); d.start(); w.start(); } }

package com.cs; public class DinnerWindows extends Thread{ private static int count =50; public void run(){ sell(); } synchronized public void sell(){ while (count>0) { count--; System.out.println("当前窗口："+Thread.currentThread().getName()+"剩余："+count+"份"); } try { Thread.sleep(20); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
