本文主要是介绍多线程实现生产者消费者模型，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！ 
package com.atgu;

import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.ReentrantLock;
class ShareDate1{
    private int num=0;
    ReentrantLock lock = new ReentrantLock();
    Condition condition = lock.newCondition();
    public void increment() throws InterruptedException {
        while (num!=0)
        {
            condition.await();
        }
        num++;
        System.out.println(Thread.currentThread().getName()+"==="+num);
    }
    public void decrement() throws InterruptedException {
        while (num==0)
        {
            condition.await();
        }
        num--;
        System.out.println(Thread.currentThread().getName()+"==="+num);
    }





}
public class produttorAndConsumer {


    public static void main(String[] args) {
        ShareDate1 shareDate1 = new ShareDate1();


        new Thread(
                ()->{
                    for (int i = 5; i > 0; i--) {
                        try {
                            shareDate1.increment();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }



                }

        new Thread(
                ()->{
                    for (int i = 5; i > 0; i--) {
                        try {
                            shareDate1.decrement();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }



                }

        ).start();

    }
