Java? Ok so thats for web hacking, BUT system/network hacking isn't connected with java? Right? I had some suggestions about Python and C++, but I don't know which one is superior? Any advice?

LOLing...Java is a very versatile, cross platform language that can be used for just about anything you can imagine, within common sense reason.
And aside from my humorous inference regarding Java, the best programming language is the programming language that fits the exact needs each individual requires.
For that, it will depend solely upon you.
Though were I in beginning the IT field, I'll opinionate perhaps Python being a good starting language and leave an opening for other Members to give their own personal experience a chance to speak.
