3.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);&n
