Calm down now. Take a few deep breaths. There now. It's a-a-a-a-all going to be
alright. Are you going to be okay?
Okay, now what seems to be the problem here?

Well then, it seems to me that the output (in full) should be:
-------------------------------
Value is:: 10
returnString is:: 15
-------------------------------
As for the reason, that is quite simple. Java passes variables of primative type
(like "int deepak") to method arguments (line "int x") by value.
For more information, check out the "Language Basics" lesson of the "Learning the Java
Language" trail of Sun's online Java tutorial, here:

There. Better now?
