多線程與高併發-併發容器6_3:LinkedBlockingQueue的實現

案例

線程a往隊列裏添加元素，線程c在隊列裏取元素，兩個線程同時進行並保證線程安全

package com.inspire.juc.c_025;

import java.util.Random;
import java.util.concurrent.BlockingQueue;
import java.util.concurrent.LinkedBlockingQueue;
import java.util.concurrent.TimeUnit;

public class T05_LinkedBlockingQueue {
    static BlockingQueue<String> strs=new LinkedBlockingQueue<>();
    static Random r=new Random();

    public static void main(String[] args) {
        new Thread(()->{
            for(int i=0;i<100;i++){
                try {
                    strs.put("a"+i);
                    TimeUnit.MILLISECONDS.sleep(r.nextInt(1000));
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        },"p1").start();

        for(int i=0;i<5;i++){
            new Thread(()->{
                for(;;){
                    try {
                        System.out.println(Thread.currentThread().getName()+" take - "+strs.take());
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            },"c"+i).start();
        }
    }
}

附

LinkedBlockingQueue是無界的，底層原理是Condition的park等方法
