Two Questions. One About Collision of Rectangles , Other about libgdx Logic in

Newbie & Debugging Questions
#1

Hi guys.
/edited due to no replies/ :smiley:
First Question :
I got that class below.
I need to know The (x;y) intersection of them ( the two Rectangles that im checking the collision), so when they do intersect , i can gen an explosion.How can i find the x;y intersection?

Second Question:
How do you guys do when you have a 2D game with several levels, how do you trade the GameView? i mean, the AppListener?
I mean, how do you manage several levels in your game?

Plus, if you could JUDGE my code, telling all the bad things of it so i can go research/learn how to improve it,i would be hAppY :smiley:

Thanks guys, sorry for bothering you in any case :D.
