Different programming languages are referred to as being at different "levels", this describes how close they work to core logic of a computer and generally the lower you go, the less english-like and more code-like the programming language syntax becomes. The main advantage to programming in a low-level language is that they are fast, but it also means that you have more control over the resources which your program consumes, this makes low-level languages ideal for systems programming (operating systems for example).
Out of the three you posted, Python is the "highest level" and allows you to do a lot with little code, it will teach you programming logic and structures and therefore I'd recommend that.
Java uses C style syntax and so it may be a good idea to pick this up after, as a load of popular programming languages use this style of syntax and it would set you up for a variety of programming jobs if you managed to get decent at programming using this style of language, it also puts declaring types etc. in your hands.
I wouldn't start with C++ as there's a lot you would have to do straight away which you would have no idea about but would be much easier to pick up once you've worked with a language Java which requires you to do a little bit more yourself.
Heiser got a reaction from minibois in Python vs C++ vs Java vs other
