New content! Fun!

I've found that, although I know most of this code, I don't know/never payed attention to all of the vocabulary. There are also some smaller things, like scope, that I never learned. A string is, obviously, a string of variables, but I am wondering how it is stored. It has an adjustable size, so it can't be an array, it would be silly to use a stack, meaning there must be a way to have a "variable" that stores multiple values with an adjustable limit to the amount of values.

I'm still waiting for the day when we learn about static vs. non-static. I keep finding things that seem insanely useful and then being incapable of using them because they are non-static. InputStream is a prime example, I was interested and wanted to mess with it, only to find that I couldn't use read() with out.print(). I understand the curriculum, though I feel like we should learn more general code (if, for, while, etc.) before learning about methods that aren't immediately useful.
