What exactly does the private or public mean in java coding. I know it has to do with who or what can read the variable but would like a simple explanation if possible.

Oh and the Return function as well.

Thanks guys!

Welcome to JavaRanch.

The 'public' and 'private' keywords are for access control of class members. You'll have to understand some object oriented programming concepts to understand what this means and what it's for.

See this in Sun's Java Tutorials:
Object-Oriented Programming Concepts
Controlling Access to Members of a Class

The 'return' keyword is used to return a value from a method.
See: Returning a Value from a Method
