今天扣丁学堂Java培训老师给大家介绍一下关于Java生产者消费者模式,结合实例形式分析了java生产者消费者模式的相关组成、原理及实现方法,首先java的生产者消费者模式,有三个部分组成,一个是生产者,一个是消费者,一个是缓存,这么做有什么好处呢?下面我们一起来看一下吧。
/**
* 我是生产者,负责生产
*/
public class Product implements Runnable {
private Queue q;
public Product(Queue q) {
this.q = q;
}
@Override
public void run() {
try {
for (int i = 0; i < 3; i++) {
q.product("test" + i);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
/**
*我是消费者,负责消费
*/
public class Consumer implements Runnable {
private Queue q;
public Consumer(Queue q){
this.q = q;
}
@Override
public void run() {
try {
for(int i=0 ; i < 3 ; i++){
q.consumer();
}
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
/**
*
*我是缓存,负责产品的存(生产后的放置)取(消费时的获取)
*/
public class Queue {
private final Object lock = new Object();
private List<String> list = new ArrayList<String>();
public void product(String param) throws InterruptedException {
synchronized (lock) {
System.out.println("product生产");
list.add(param);
lock.notify();
lock.wait();
}
}
public void consumer() throws InterruptedException {
synchronized (lock) {
lock.wait();
System.out.println("product消费");
if (list.size() > 0) {
list.remove(list.size() - 1);
}
lock.notify();
}
}
}
public class TestMain {
public static void main(String[] args) {
Queue q = new Queue();
Product p = new Product(q);
Consumer s = new Consumer(q);
Thread t1 = new Thread(p);
Thread t2 = new Thread(s);
t1.start();
t2.start();
}
}
