wait跟notify实现的生产者消费者线程交互

wait和notify实现的生产者消费者线程交互


public class ProductTest {
public static void main(String args[])
{
Repertory repertory=new Repertory();
new Thread(new Producer(repertory)).start();
new Thread(new Consumer(repertory)).start();
}
}


class Repertory{

public synchronized void addProduct(){
if(this.product>=5)
{
try{
this.wait();
}catch(Exception e)
{
e.printStackTrace();
}
}
else
{
product++;
System.out.println("生产者生成第"+product+"个产品");
this.notifyAll();
}
}

public synchronized void getProduct(){
if(this.product<=0)
{
try{
this.wait();
}catch(Exception e)
{
e.printStackTrace();
}
}else
{
System.out.println("消费者取走了第"+product+"个产品");
product--;
this.notifyAll();
}
}

}
