我按照视频敲的代码,不知道哪里错了,只会运行3次就停了,求高手指点!- class Resource
- {
- private String name;
- private int count=1;
- private boolean flag =false;
- public synchronized void set(String name)
- {
- if(flag)
- try{this.wait();}catch(Exception a){}
- this.name=name+"--"+count++;
-
- System.out.println(Thread.currentThread().getName()+"...生产者...."+this.name);
- flag=true;
- this.notify();
- }
- public synchronized void out()
- {
- if(!flag)
- try{this.wait();}catch(Exception a){}
- System.out.println(Thread.currentThread().getName()+"...消费者...."+this.name);
- flag=false;
- this.notify();
- }
- }
- //---------------------------------
- class Producer implements Runnable
- {
- private Resource res;
- Producer(Resource res)
- {
- this.res=res;
- }
- public void run()
- {
- while(true)
- {
- res.set("商品");
- }
- }
- }
- //----------------------------------
- class Consumer implements Runnable
- {
- private Resource res;
- Consumer(Resource res)
- {
- this.res=res;
- }
- public void run()

- res.out();

- }
- //------------------------------------
- class ProduceConsumerDemo
- {
- public static void main(String[] args)
- {
- Resource r =new Resource();
- Producer pro=new Producer(r);
- Consumer con=new Consumer(r);
-
- Thread t1=new Thread(pro);
- Thread t2=new Thread(con);
- t1.start();
- t2.start();
