Hey, why dont you instantiate the random number generator on the class level.
Hey, why dont you instantiate the random number generator on the class level. does it mean that everytime i tap the button the class is instantiated? Thanks.

Good catch! That could totally be a class variable. Strictly speaking it would use less resources, but functionally it wouldn't make any difference; creating a Random object isn't expensive and Button clicks aren't that frequent.
Though one place where you want to watch this sort of stuff VERY closely is in video games. If you're rendering 60 frames a second and you're allocating a new variable each time, you'll definitely run into some problems.
