juc包中等待唤醒机制实现

     参考等待唤醒机制中原始代码

    

package com.neutron.thread.juc;

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

public class Resource {
	private String resName;
	private int count = 1;
	private boolean flag = false;
	/**
	 * 锁对象
	 */
	private Lock lock = new ReentrantLock();
	/**
	 * 生产者线程处理对象,代理Object
	 */
	private Condition proCondition = lock.newCondition();
	/**
	 * 消费者线程处理对象,代替Object
	 */
	private Condition conCondition = lock.newCondition();
	
	public void set(String resName) {
		lock.lock();
		try {
			while(flag) {
				proCondition.await();
			}
			this.resName = "product [food:" + resName + count++ +"]";
			System.out.println(this.resName);
			this.flag = true;
			conCondition.signal();
		} catch (InterruptedException e) {
			e.printStackTrace();
		} finally {
			lock.unlock();
		}
	}
	
	public void get(){
		lock.lock();
		try {
			while(!flag) {
				conCondition.await();
			}
			System.out.println("consumer [deal: " + this.resName + "]");
			this.flag = false;
			proCondition.signal();
		} catch (InterruptedException e) {
			e.printStackTrace();
		} finally {
			lock.unlock();
		}
	}
}

  

package com.neutron.thread.juc;

public class Producter implements Runnable {
