【Java】【多线程】卖票
作者:互联网
分别继承Thread和实现Runnable,创建三个线程卖票。
package com.itheima;
class MyThread extends Thread{
private static int tickets = 100;
@Override
public void run() {
while (true){
if(tickets > 0){
System.out.println(Thread.currentThread().getName() + ": 卖票,票号为:" + tickets );
tickets--;
}else return;
}
}
}
public class T {
public static void main(String[] args) {
MyThread thread1 = new MyThread();
thread1.setName("窗口1");
thread1.start();
MyThread thread2 = new MyThread();
thread2.setName("窗口2");
thread2.start();
MyThread thread3 = new MyThread();
thread3.setName("窗口3");
thread3.start();
}
}

thread2.setName("窗口2");
thread2.start();
Thread thread3 = new Thread(myThread);
thread3.setName("窗口3");
thread3.start();
}

仔细会发现有重票问题。
