定义运行方法
package com.company; // 包名
import java.util.concurrent.locks.ReentrantLock;
import java.util.concurrent.locks.Lock;
public class ticket implements Runnable{
private int ticketnum = 100; //全局变量
Lock lock = new ReentrantLock(true); //对象
@Override
public void run() { //写 run()
while (ticketnum > 0){
lock.lock(); //加锁
try {
if (ticketnum > 0){
try {
Thread.sleep(100); //工作时间
} catch (InterruptedException e) {
e.printStackTrace();
}
String name = new Thread().currentThread().getName();
System.out.println("线程"+name+"销售电影票"+ticketnum--);
}
}
finally {
lock.unlock(); //解锁
}
}
}
}
将方法加入到线程中
package com.company;
import com.company.ticket;
public class shoupiao {
public static void main(String[] args) {
ticket ticket = new ticket();
Thread thread1 = new Thread(ticket,"窗口1");
Thread thread2 = new Thread(ticket,"窗口2");
Thread thread3 = new Thread(ticket,"窗口3");
thread1.start();
thread2.start();
thread3.start();
}
}
