Need advice regarding java libriaries

Hello guys,

I’m thinking about programming a little game in java for the fun of it. I was thinking of making a 2D RPG with some TBS elements in it.

Now, I’m confident in my abilities to create the logical structures behind the elements I need to incorporate but my java skills are, at most, at a beginner level. My question to you lot is what you would recommend to start with? I had a look online and found some interesting tools in lwjgl, slick2d and libgdx. Should I use all of these or only a subset? Should I use something else? Any input is kindly appreciated.

Thanks,
NGD
