I need some very basic collision detection tutorial. ( Java )
So, I'm about to apply for a trainee/junior position and they told me to practice some string manipulation (which I already did) and some collision detection, very basic, like detecting collision between squares. I googled but I found nothing but very advanced stuff. Couldn't find any sort of basic introduction to collision detection.

I'm already practicing at Codingbat, but I couldn't find any collision detection ex.

Any link will be greatly appreciated.

Thanks.
