Java subclass a domain model if you have to store or manipulate instances of it in order to implement a requirement 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 a unique name since somebody in the future might want to import the packages containing both classes and hence create a name clash abstract if it has one or more abstract methods subclass in a file of the same name The Basics of Java particular low-level subsystems the pieces of data that describe some entity, so that programmers can manipulate that data as a unit the details of data to hold a responsibility if the responsibility cannot be attributed to any of the existing classes
class classname
{ // declarations of variables
// declarations of constructors (discussed below)
// declarations of other methods with public ones first
}
a special-purpose function such as the user interface for a particular system its own source file variables methods an implements clause to declare that it contains methods for each of the operations specified by the interface a programmer to cope with the complexity of data elements as follows:
class variables
instance variables
constructors
the most important public methods
methods that are simply used to access variables
private methods
all instance variables and methods defined in its ancestor classes the internals of a computer system such as 'Record', 'Table', 'Data', 'Structure', or 'Information' several similar objects only one superclass a list of variables, called instance variables, corresponding to data that will be present in each instance a box with the name of the class inside in a UML class diagram data associated with each object if related aspects of a system are kept together in this module, and unrelated aspects are kept out class^2 the extends keyword
