Java第二十六天，多线程等待换新机制（严格执行化）

代码：

1.老板类：

package com.lanyue.day26;

public class bossRunnable implements Runnable {

    public myLock lock;

    public void setLock(myLock lock){

        this.lock = lock;
    }

    @Override
    public void run() {

        while(true){

            synchronized (lock){

                try {
                    Thread.sleep(1500);
                } catch (InterruptedException e) {
                    System.out.println("系统故障");
                }

                if(lock.flag()){

                    System.out.println("老板：小刘给我倒杯水去");
                    System.out.println("老板：小张给我整理一下资料");

                    lock.notifyAll();
                }
            }
        }
    }
}

2.员工一类：

package com.lanyue.day26;

public class customerOneRunnable implements Runnable {

    private myLock lock;

    @Override
    public void run() {

        while (true){

            synchronized (lock){

                if(lock.flag % 2 == 0){

                    System.out.println("小刘：老板，我有什么可以帮助你的吗？");
                    lock.flagTime++;

                    try {
                        lock.wait();
                    } catch (InterruptedException e) {
                        System.out.println("系统出现故障");
                    }

                    System.out.println("小刘：好的老板。");
                    lock.flag++;
                }
            }
        }
    }

    public void setLock(myLock lock){

        this.lock = lock;
    }
}

3.员工二类：

package com.lanyue.day26;

public class customerTwoRunnable implements Runnable {

    public myLock lock;

    public void setLock(myLock lock){

        this.lock = lock;
    }

    @Override
    public void run() {

        while(true){

            synchronized(lock){

                if(lock.flag % 2 == 0){

                    System.out.println("小张：老板，请问有什么吩咐");
                    lock.flagTime++;

                    try {
                        lock.wait();
                    } catch (InterruptedException e) {
                        System.out.println("系统出现故障");
                    }

                    System.out.println("小张:已经准备好了");
                    lock.flag++;
                }
            }
        }
    }

}

4.控制锁类：

package com.lanyue.day26;

public class myLock {

    public String name;
    public int flag = 0;
    public int flagTime = 0;

    public void setName(String name){

        this.name = name;
    }

    public boolean flag(){

        if(flagTime == 2){

            flagTime = 0;
            return true;

        }else{

            return false;
        }
    }
}

执行代码：

package com.lanyue.day26;

public class TestDemo {

    public static void main(String[] args) {

        bossRunnable boss = new bossRunnable();
        customerOneRunnable cusOne = new customerOneRunnable();
        customerTwoRunnable cusTwo = new customerTwoRunnable();

        myLock lock = new myLock();
        lock.setName("同步锁");
        boss.setLock(lock);
        cusOne.setLock(lock);
        cusTwo.setLock(lock);

        Thread one = new Thread(boss);
        Thread two = new Thread(cusOne);
        Thread three = new Thread(cusTwo);

        one.start();
        two.start();
        three.start();
    }
}
