Obj is null ya it is true but it is working in the other methods i dunno how ? and Obj has an abstract class data type so when i changed its type to the class implements the abstract one it worked but i don't think it is an object oriented designthanks

You shouldn't have to do that to fix the bug. In fact changing the type can't fix the bug by itself, it must be some side-effect. You need to find that and implement it directly. Otherwise you have code that works but you don't know why, which is not satisfactory.
