java JUC基础学习

本学习笔记内容来自尚硅谷周阳老师： 

package geovis.demo;

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

class Tiket {
    private Integer number = 68;
    //Lock实现提供比使用synchronized方法和语句可以获得的更广泛的锁定操作。
    Lock lock = new ReentrantLock();
    public void sail(){
        //lock标准使用方法为lock.lock();try{}catch{}finally{lock.unlock()}
        lock.lock();
        try {
            if(number > 0)
            System.out.println(Thread.currentThread().getName() + "卖出去第：" + (number--) + "张票" + "还剩：" + number + "张。");
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            lock.unlock();
        }
    }
}

public class Jucdemo {
    public static void main(String[] args) {
        System.out.println("开启java多线程学习");
        Tiket tiket = new Tiket();
        new Thread(new Runnable() {
            @Override
            public void run() {
                for (int i = 0;i < 70;i++){
                    tiket.sail();
                }
            }
        },"张三").start();
        new Thread(()->{for (int i=0;i<70;i++) tiket.sail();},"蓝不大").start();
    }
}
