No but seriously as others have said, it depends on what kind of stuff you're into. Java is a pretty general purpose robust language. C isnt really used much but it's important in a sense that everything is C based. Python is an interpreted scripting language which can also be used on the web (e.g Django).
Personally I would recommend JavaScript it's a really beginner friendly language and you can have lots of fun with it. The best thing is you write once and you can run it in any browser. You could also use Phaser IO to make web games with it which can also work on phones. It's really cool actually.
