多线程生产消费者模式

多线程生产消费者模式，可以进行
创建四个类
1.资源控制类：Resource
2.生产者：ProductorThread
3.消费者：ConsumerThread
4.测试类

首先定义资源类，控制资源的可见性以及资源的数量
public class Resource {
//初始化最大值
private final Integer biggestNum = 2000;
//初始化最小值
private final Integer ministNum = 550;
//线程当前数量
private volatile Integer currentNum = 500;

public synchronized void product() {
    if (currentNum > biggestNum) {
        try {
            wait();
            return;
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
    currentNum++;
    System.out.println(Thread.currentThread().getName() + "--produce--number--" + currentNum);
    notifyAll();
}

public synchronized void consume() {
    if (currentNum < ministNum) {
        try {
            wait();
            return;
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
    currentNum--;
    System.out.println(Thread.currentThread().getName() + "--consume--number--" + currentNum);
    notifyAll();
}

}

生产者：实现Runnable接口，复写run方法。
public class ProductorThread implements Runnable{

private Resource resource;

public ProductorThread(Resource resource) {
    this.resource = resource;
}
public void run() {
    while (true){
        resource.product();
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

}

消费者：实现Runnable接口，复写run方法。
public class ConsumerThread implements Runnable{

private Resource resource;

public ConsumerThread(Resource resource) {
    this.resource = resource;
}

public void run() {
    while (true){
        resource.consume();
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

}

测试类，创建资源类，创建生产消费线程进行测试。
public class ProdAndConsTest {

public static void main(String []args){

    Resource resource = new Resource();

    for (int i=0; i< 3; i++) {
        new Thread(new ConsumerThread(resource)).start();
    }
    for (int i=0; i< 3; i++) {
        new Thread(new ProductorThread(resource)).start();
    }
}

}

话不多说，亲测可用。
