its in pop, you should first save the variable and then reduce the index and return it.

The code is in C++, so, there should be a ; after brace which ends class, and other thing is variables are cannot be initialized in class - use a constructor

Doesn't look like c++ to me
1. no boundary checking in push() => can exceed maxCount
2. no boundaries checking in pop() => index can become negative
3. object[index]=null in pop() with saving the value into temp variable for garbage collection

1.)index shud be static
2.) both the methods shud be synchronized

1.maxCount should be final static.
2.It should have some boundary check in push method to make sure the maxium number of object in the array is 1000.
3.In pop method it should add if(index>=1){}, otherwise index could be negative.
