For you to cast from object to int, i would advice you to use this method which is as follow if the Integer.ParseInt(object.toSring())
The string representation of the object is returned by the toString() and the string return value is passed as an arguement to the Integer.ParseInt() method. 
Good luck, should you need further clarification, do let me know

But of course you have to catch any 'NumberFormatException', and it's really bad design, and 
why are you answering a five-year-old thread?

Unlikely the OP is still checking on this thread, wouldn't you think?

And they might want to check with someone who gives better advice anyway.

Like, declare the method to take an 'int' in the first place.
