Re: Java

Java is a programming language used by certain programs (you might run one) and certain webpages (you might occasionally view one). If you run such a program on your PC or visit such webpages you need it.

If you don't need it, you can safely delete it (uninstall all versions you see from control panel).
If you do need it, it's best to update.

If you're not sure delete it and wait for a call to reinstall it. Then you know what it is for.

You don't need it, but it's convenient to have (in my opinion). If you keep and use it, it's mandatory to keep it up to date. This is for security reasons, since Java can be used for exploits. There will be critical updates released right away if there's a security flaw, and updating right away is important.
