Hi, I'm completely new to Java, and I'm already lost with the installation. :p

I'm on the custom install page and I see

Source Code: Source code for classes that comprise the public API of Java.
Public JRE: The standalone JRE. Any application can use this JRE. It registers Java Plug-in and Java Web Start with the browsers and system.

There is also Demo and Samples, and Development Tools, which don't have an option for not installing.

I don't know if I should install those two features.

You can install them they will not harm you, but if you do not want them you can leave it out.

I don't want the extra space, but do you think I might need to use them? (Whatever they are for)
