Programming exercises

So right now I have nothing I need to code for myself, or at least nothing I'd be ABLE to code for myself, but I still want to improve the quality of my code/get better/learn more.

Does anyone know of a website with programming exercises of beginner-intermediate level for Sepples and/or Java that would actually interest me?

I googled around a little and most of the exercises there were shitty university assignments.
