Variables
Tuesday 24th, September 2006
Variables
Variables. Where would we be without them? Variables are used to temporarily store data while the program is running.
Information is contained within a named reference - the variable name. A variable can only store one type of data in its
lifetime, so for example custID might hold an integer (whole number) representing the customer's number.

Methods
Everything in Java is a class. The sub-functions / modules within a class are called methods. These are
"doing" things. They allow the object's callers to perform certain actions, as well as allowing the object to
internally (privately) run functionality.
