I googled a little but got no short good explanation, what is a package?
I mean, here, in this tutorial (thanks to whoever that had this in signature) Free Java Video Tutorial Variables and Datatypes Part 2
He says to import under package, but i do not use a template for writing new java-files, that means, I haven't ever used this "package"
Can someone, in short termes explain what it is and if it's needed?
Edit: While I'm at it, without googling, what does the "private" "final" and so on stuff do? I mean, someone here in the forum wrote "final int", does that mean simply that that int is unchangeable?
