Java多线程--模拟窗口售票问题

本章通过多个Java多线程实例对多线程进行学习

1. 模拟窗口售票问题

1. 代码

package test;

public class TestSaleTickets {

    public static void main(String[] args) {
        Counter counter = new Counter();
        new Thread(counter, "柜台A").start();
        new Thread(counter, "柜台B").start();
        new Thread(counter, "柜台C").start();
    }

}

/**
 * 柜台售票
 */
class Counter implements Runnable{

    //总票数
    public static int tickets = 20;

    @Override
    public void run() {
        while (tickets > 0){
            synchronized (this){
                if(tickets > 0){
                    System.out.println(Thread.currentThread().getName() + "卖出了第" + tickets + "张票");
                }else {
                    System.out.println(Thread.currentThread().getName() + "票卖完了");
                }
                try {
                    Thread.sleep(1000);
                    tickets--;
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
