静态代理

• 静态代理实现
• 1.定义真实类 PickTicket 并实现 Runnable 接口
• 2.定义代理类 （例如系统标准的进程类：Thread） 并把 真实类 PickTicket 传入代理类汇总
• 4.代理类调用 start 启动进程
• *

真实类 PickTicket

package cn.thread;


/**
 * @author Duoduo
 * @version 1.0
 * @date 2017/4/19 15:25
 */
public class PickTicket implements Runnable {

    private int ticketNumber = 100;
    private  boolean flag = true;


    @Override
    public void run() {
        System.out.println(Thread.currentThread().getName());
        while (flag) {
            test1();
        }
    }

    private synchronized void test2() {

        if (ticketNumber <= 0) {
            flag = false;
            return;
        }
        try {
            Thread.sleep(1);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println(Thread.currentThread().getName() + " get the ticket :" + " " + ticketNumber--);
    }

    private void test1() {
        if (ticketNumber <= 0) {
            flag = false;
            return;
        }
        try {
            Thread.sleep(1);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }

        System.out.println(Thread.currentThread().getName() + " get the ticket :" + " " + ticketNumber--);

    }

}
