Java class in an imported package 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 Java class in a package 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 directory with the same name as the package 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
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 name if the package is imported class^2
