Anything similar to AS3's Flixel library?

Hi, I’ve been developing games for a long time. Recently, I fell in love with Flixel, a game development library for AS3, and I’m wondering if there’s anything like that for java. If there’s not, could someone tell me what library/engine might be best suited for making a platformer game in Java? Thanks!

EDIT: Also should note that I would prefer something that can create applets and executables

I have tried two popular libraries/frameworks for game developing using Java: Slick and libGDX. Unfortunately, I have never used Flixel, so I can’t compare if they have similar features.

There are many accurate descriptions of both around the forums, made by folks that know way better than me.

Anyway, I think a good way to fall in love for a framework is reading some of its beginner tutorials. I leave you here some starting tutorials for Slick and libGDX.
