Some days ago, i saw a nice example of calculator on these pages, after I imported on Eclipse I understood, that what i needed was a nice tutorial to understand it better, so I found one really cool,
I would like to fix the NPE, but just I am not able.
and this is the calculator, I started to modify a bit to play with the code, thanks.
