生产者与消费者，这里出现什么问题
程序代码：
public class PandC {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
Procedure procedure = new Procedure();
Custom custom = new Custom();
procedure.start();
custom.start();
}
}
class Baozi{
int id;
Baozi(int id){
this.id=id;
}
public String toString (){
return ":"+id;
}
}
class Panel{
int index=0;
Baozi[] baozi =new Baozi[10];
public synchronized void inPut(Baozi bz){
while(index==baozi.length){
try {
System.out.println("等待消费中~~~~~~~~");
this.wait();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
this.notify();
baozi[index]=bz;
index++;
}
public synchronized Baozi outPut(){
while(index==0){
try {
System.out.println("等该生产中~~~~~~~~");
this.wait();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
this.notify();
index--;
return baozi[index];
}
}
//生产者
class Procedure extends Thread{
private Panel p= new Panel();
public void run(){
//for(int i=p.index;i<p.baozi.length;i++){
for(int i=0;i<30;i++){
Baozi bz = new Baozi(i);
p.inPut(bz);
System.out.println ("生产第"+bz+"号包子");
try {
Thread.sleep(500);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
//消费者
class Custom extends Thread{
private Panel p= new Panel();
public void run(){
//for(int i=p.index;i>=0;i--){
for(int i=0;i<30;i++){
Baozi bz=p.outPut();
System.out.println ("消费第"+bz+"号包子");
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}
