Your code has one compiler error, and the one you mention is not it. Either you must rebuild your source, or you must PostRealCode. My guess is the former.

You are right!

"Unresolved compilation problem" indicates that you have multiple source files and that they are not in sync: you have class files somewhere from a previous version of the source code. The solution is to delete these old class files and recompile all the source code.

Also, method getCode must be static

The only error i can see is that method getCode should be declared static. when i changed it the code worked fine!

or In main you could create a ReadIniFile object and then make a call to the getCode method from that object.
