线程通信机制详解-优快云博客

本文深入探讨了线程之间的基本通信机制，通过生产者-消费者模式的实例代码，详细解析了如何使用Java的synchronized关键字和wait/notify方法实现线程间的同步与通信。文章通过具体的生产者和消费者类的实现，展示了如何在多线程环境中解决资源竞争问题。

知识点：线程基本通信

生产者：

package com.fengunion.dxc.pc;

import java.util.List;

public class Producer implements Runnable {

    private List<String> list;

    public Producer(List<String> list) {
        this.list = list;
    }

    @Override
    public void run() {
        while (true){
            synchronized (list){
                if(list.size()==1){
                    System.out.println("队列已满....");
                    try {
                        list.wait();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
                list.add("1");
                list.forEach(x ->{
                    System.out.println("生产数据："+x);
                });
                list.notify();
            }
        }
    }
}

消费者：

package com.fengunion.dxc.pc;

import java.util.List;

public class Consumer implements Runnable {
    private List<String> list;
    public Consumer(List<String> list){
        this.list=list;
    }
    @Override
    public void run() {
        while (true){
            synchronized (list){
                if(list.size()==0){
                    System.out.println("队列为空");
                    try {
                        list.wait();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }

                }
                list.forEach(x ->{
                    System.out.println("消费数据："+x);
                });
                list.remove("1");
                list.notify();
            }
        }
    }
}

测试：

public static void main(String[] args) {
    List<String> list=new ArrayList<>();
    Producer p=new Producer(list);
    Consumer c = new Consumer(list);
    Thread thread = new Thread(p);
    Thread thread1 = new Thread(c);
    thread.start();
    thread1.start();

}
