producer/consumer

[srijan sharma]

hi,
the folowing code does not give desired output...
it is from sun tutorial
// ******** storage class////////

public class store
{
private int contents;
private boolean available=false;
public synchronized int get()
{
while(available==false)
  {
try {
wait();
    }catch(InterruptedException e)
           {
System.out.println("waiting for produer");
           }
  }
available=false;
notifyAll();
return contents;
}

public synchronized void put(int value)
{
while(available==true)
  {
try {
wait();
    }catch(InterruptedException e)
           {
System.out.println("waiting");
           }
  }
contents=value;
available=true;
notifyAll();
}
}
////**********producer class***************

public class producer extends Thread
{
private store st;
private int number;
public producer(store s,int number)
{
st=s;
this.number=number;
}
public void run()
{
for(int i=0;i<10;i++)
{
st.put(i);
System.out.println("producer "+this.number+"put " + i);
try
{
//sleep((int)(Math.random()*100));
sleep(2000);
}catch(Exception e)
{}
}
}
}

///////***********conumer class
public class consumer extends Thread
{
private store s;
private int number;
public consumer(store st,int number)
{
s=st;
this.number=number;
}
public void run()
{
int value=0;
for(int i=0;i<10;i++)
{
value=s.get();
System.out.println("consumer 
#"+this.number+"got:"+value);
}
}
////// main method
public class pconsumer{
public static void main(String args[])
{
store s = new store();
producer p1 = new producer(s,1);
consumer c = new consumer(s,1);
p1.start();
c.start();
}
}
