在生产者-消费者模型中，在原有代码基础上，把队列独立为1个类实现，通过公布接口，由生产者和消费者调用。

public class Consumer implements Runnable {int n;CountDownLatch countDownLatch;public Consumer(BlockingQueue<Integer> blockingQueue, int n, CountDownLatch countDownLatch) {this.n = n;this.countDownLatch=countDownLatch;}@Overridepublic void run() {for(int i=0;i<n;i++){try {int cur=PACqueue.consume();/*System.out.println(this.toString()+i+"处理"+cur);*/isPrime(cur);/*   System.out.println("消费"+blockingQueue.size());*/} catch (InterruptedException e) {e.printStackTrace();}}System.out.println("消费者完成");countDownLatch.countDown();}int isPrime(int n){	//返回1表示判断为质数，0为非质数，在此没有进行输入异常检测double n_sqrt;if(n==2 || n==3) return 1;if(n%6!=1 && n%6!=5) return 0;n_sqrt=Math.floor(Math.sqrt((float)n));for(int i=5;i<=n_sqrt;i+=6){if(n%(i)==0 | n%(i+2)==0) return 0;}return 1;}}

public class Model {public  static void excute(int producerNum,int consumerNum,int num,CountDownLatch countDownLatch){BlockingQueue<Integer> blockingQueue=new LinkedBlockingQueue<>(num);for(int i=0;i<producerNum;i++){new Thread(new Producer(blockingQueue,num/producerNum,countDownLatch)).start();}for(int i=0;i<consumerNum;i++){new Thread(new Consumer(blockingQueue,num/consumerNum,countDownLatch)).start();}}public static void main(String[] args) {CountDownLatch countDownLatch=new CountDownLatch(6);long s=System.currentTimeMillis();excute(2,4,1000000,countDownLatch);try {countDownLatch.await();} catch (InterruptedException e) {e.printStackTrace();}System.out.println((double) (System.currentTimeMillis()-s)/1000);}
}

public class PACqueue {//Java 阻塞队列在队列为空时，获取元素的线程会等待队列变为非空。当队列满时，存储元素的线程会等待队列可用。private static BlockingQueue<Integer> blockingQueue=new LinkedBlockingQueue<>(1000000);public static void produce (int n)throws InterruptedException{blockingQueue.put(n);}public static int  consume ()throws InterruptedException{return blockingQueue.take();}}

public class Producer implements Runnable{int n;CountDownLatch countDownLatch;public Producer(BlockingQueue<Integer> blockingQueue, int n,CountDownLatch countDownLatch) {this.n = n;this.countDownLatch=countDownLatch;}@Overridepublic void run() {Random ra =new Random();for(int i=0;i<n;i++){try {/*  System.out.println(this.toString()+i+"生产");*/PACqueue.produce(ra.nextInt(2000000000)+1);/*    System.out.println("生产"+blockingQueue.size());*/} catch (InterruptedException e) {e.printStackTrace();}}System.out.println("生产者完成");countDownLatch.countDown();}
