生产者消费者问题

容器：
public class SynList {

    private int index = 0;
    private static final int MAX = 5;
    private Wotou []data = new Wotou[MAX];

    public synchronized void push(Wotou wotou){
        while (index == MAX){
            System.out.println("已满");
            try {
                wait();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        System.out.println("add id:"+wotou.getId());
        data[index] = wotou;
        index++;
        this.notifyAll();
    }

    public synchronized Wotou pop(){
        while (index == 0){
            System.out.println("已空");
            try {
                wait();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        index--;
        System.out.println("pop index:"+index);
        Wotou wotou = data[index];
        System.out.println("remove id:"+wotou.getId());
        this.notifyAll();
        return wotou;
    }

    public static void main(String[] args) {

        SynList list = new SynList();
        new Thread(new Productor(list)).start();
        new Thread(new Consumer(list)).start();
    }
}

生产者：
public class Productor  implements Runnable{

    private SynList list ;

    public Productor(SynList list ){
        this.list = list;
    }

    @Override
    public void run() {
        for (int i = 0; i < 20; i++) {
            Wotou wt = new Wotou(String.valueOf(i));
            list.push(wt);
            try {
                Thread.sleep((int)Math.random()*200);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

 

消费者：

public class Consumer implements Runnable{

    private SynList list ;

    public Consumer(SynList list ){
        this.list = list;
    }

    @Override
    public void run() {
        for (int i = 0; i < 20; i++) {
            Wotou wtTo = list.pop();
            System.out.println("消费：" + wtTo);
            try {
                Thread.sleep((int)Math.random()*1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}
