本题程序中实现了一个“生产者一消费者问题”。生产者产生一个随机数存入DataPool类中，消费者从中取出数据。DataPool类一次只能存放一个数据。请更正题中带下划线的部分。
注意：不改变程序的结构，不得增行或删行。
class DataPool
private int data;
private boolean isFull;
public DataPool()
isFull=false;
public synchronized void putData(int d)
if(isFull= =true)
try
this.notify();
catch(InterruptedException e)
data=d;
isFull=true;
System.out.println("生产了一个数据:"+data);
this.notify();
public synchronized int getData()
if(isFull= =false)
try
this.wait();
catch(InterruptedException e)
isFull=false;
System.out.println("消费了一个数据"+data);
this.wait();
return this.data;
boolean getIsFull()
return isFull;
class Producer extends Thread
DataPool pool;
public Producer(DataPool pool)
this.pool=pool;
public void run()
for(int i=0; i＜10; i++)
int data=(int) (Math.random()*1000);
try
//用于生产数据
sleep(data);
catch(InterruptedException e)
pool.putData(data);
class Consumer implements Runnable
DataPool pool;
public Consumer(DataPool pool)
this.pool=pool;
public void run()
for(int i=0; i＜10; i++)
int data=pool.getData();
try
//用于处理数据
sleep((int) (Math.random()*1000));
catch(InterruptedException e)
public class advance
public static void main(String[] args)
Data Pool pool=new Data Pool();
Producer pro=new Producer(pool);
Runnable con=new Consumer(pool);
Thread conTh=new Thread(con);
pro.start();
conTh.start();
