Why you declare variables at the beginning of the class and some other times within its loops or after other code lines?

I don't know if you mention it later on during the course, but the first occurrence came up during this lesson I think. Also, probably this is a OOP language-related concept, and not necessarily part of this course, but it'd be great to know the reason now that I'm learning it here.
