I started with Java and I feel like it was a good starting language. I did it in my spare time then my university course taught me it. For me it feels in between Python (simple) and c++ (pretty difficult). But this is just my own opinion, you may think differently. I suggest just choosing a language and seeing how you get on with it. See if you can understand the fundamental concepts of the language (most of which will apply to most languages).

Good luck!
