java线程通信--生产者消费者-优快云博客

文章描述了一个使用Java编写的多线程生产者-消费者模型，展示了三个生产者线程轮流生产商品，两个消费者线程消耗商品，实现并发控制。

import java.util.ArrayList;
import java.util.List;

public class Desk {
    private List<String> list = new ArrayList<>();


    //三个生产者
    public synchronized void put(){
        try{
            String  name = Thread.currentThread().getName();
            if(list.size()==0){
                list.add(name+"生产的商品");
                System.out.println(name+"生产了一个商品");
                Thread.sleep(2000);
                //唤醒别的线程,等待自己
                this.notifyAll();
                this.wait();
            }else {
                //有产品了 继续唤醒别的线程  等待自己
                this.notifyAll();
                this.wait();
            }

        }catch (Exception e){
            e.printStackTrace();
        }




    };


    //两个消费者
    public synchronized void get(){
        try{
            String  name = Thread.currentThread().getName();
            if (list.size()==1){
                System.out.println(name+"对"+ list.get(0) +"进行了消费");
                list.clear();
                Thread.sleep(2000);
                this.notifyAll();
                this.wait();
            }else {
                this.notifyAll();
                this.wait();
            }
        }catch (Exception e){
            e.printStackTrace();
        }
    };
}

//执行代码

public class ThreadTest2 {

    public static void main(String[] args) {

        Desk desk =new Desk();

        new Thread(()->{
            while (true){
                desk.put();
            }
        },"provide一").start();


        new Thread(()->{
            while (true){
                desk.put();
            }
        },"provide二").start();


        new Thread(()->{
            while (true){
                desk.put();
            }
        },"provide三").start();


        new Thread(()->{
            while (true){
                desk.get();
            }
        },"consumer一").start();


        new Thread(()->{
            while (true){
                desk.get();
            }
        },"consumer二").start();
    }

}
