标@Java多线程初次接触synchronize

package tiket;

import java.nio.channels.SeekableByteChannel;

public class Ticket {
public static void main(String []args){
Sell1 sell1 = new Sell1();
new Thread(sell1).start();
new Thread(sell1).start();
new Thread(sell1).start();

}

}
class Sell1 implements Runnable{

private int ticket = 100;
private boolean loop = true;

public synchronized void m(){//同步方法，在同一时刻只能有一个线程来执行run方法。
    if(ticket <= 0){
        System.out.println("票卖完了！");
        loop = false;
        return;
    }
    try {
        Thread.sleep(50);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
    System.out.println("窗口：" + Thread.currentThread().getName() + "  卖出一张" + "还剩：" + (--ticket));
}
@Override
public void run(){
    while(loop){
        m();
    }
}

}
