This is a simple question, but I am really bugged by it. I was trying to find a duplicate, and googled it, but I was more surprised when I couldn't find a satisfying answer.
import java.util.Scanner;
In this statement .Scanner is the class,
.util is the name of the package
What is java or javax or whatever would stand before the first period in general?
UPDATE:
I also found this picture:
