ArrayBlockQueue

通過數組存儲數據

阻塞:

package com.yulang.threadpool.java8;

import org.springframework.scheduling.annotation.Scheduled;

import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.TimeUnit;

public class Test06 {

    public static void main(String[] args) throws InterruptedException {

        ArrayBlockingQueue arrayBlockingQueue  =new ArrayBlockingQueue(3,false);
        new Thread(()->{
            while (true) {
                System.out.println(arrayBlockingQueue.poll());
                try {
                    TimeUnit.SECONDS.sleep(1);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }).start();

        for(int i=0;i<6;i++){
            new Thread(()->{
                try {

                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }).start();
        }

        TimeUnit.SECONDS.sleep(10);

    }

}

public void put(E e) throws InterruptedException {
        checkNotNull(e);
        final ReentrantLock lock = this.lock;
        lock.lockInterruptibly();
        try {
            while (count == items.length)
                notFull.await();
            enqueue(e);
        } finally {
            lock.unlock();
        }
