生产-消费模式的synchronized和lock实现（十）

lock：

package com.net.thread.lock;

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

    public static void main(String[] args)
    {

        for(int j = 0; j < 20; j++)
        {

            new Thread(new Runnable()
            {

    }

    static class MyThread
    {
        private boolean isPut = true;
        public synchronized void put()
        {

            }

            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            isPut = false;
            this.notifyAll();
        }

                }
            }
            for (int i = 0; i < 2; i++) {
                System.out.println("take方法 :-------------------" + i  + "  :  " + Thread.currentThread().getName());
            }

            try {
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            this.notifyAll();
