Java class in a file of the same name The Basics of Java class^2
class classname
{ // declarations of variables
// declarations of constructors (discussed below)
// declarations of other methods with public ones first
}
only one superclass variables its own source file data associated with each object particular low-level subsystems side effects if it does not modify any data, and does not leave behind any information, other than its result, that would have an effect on other computations elements as follows:
class variables
instance variables
constructors
the most important public methods
methods that are simply used to access variables
private methods
Java module an implements clause to declare that it contains methods for each of the operations specified by the interface a special-purpose function such as the user interface for a particular system a unique name since somebody in the future might want to import the packages containing both classes and hence create a name clash if related aspects of a system are kept together in this module, and unrelated aspects are kept out abstract if it has one or more abstract methods

utility 9.2 - Principles Leading to Good Design utility^2 when using a certain procedure, a programmer does not need to worry about all the details of how it performs its computations; he or she only needs to know how to call it and what it computes procedural abstraction variables data associated with each object method a comment at the top describing the purpose of the class, how it should be used, its authors and its history of modification A method or class that has wide applicability to many different subsystems and is designed to be reusable the unit of data abstraction in an object-oriented program
