Casting : Converting one type of value to another. Character : A value used in text. Class : A collection of methods and variables that an object can have, or a template for building objects. .class file : A file containing the machine independent Java Byte code. Class variable : A variable allocated once per class. Class variables have global class scope and belong to the entire class instead of an instance. Comparison operators : >, =,
