abstract method a comment at its head if the method is non-obvious equivalent to the terms "routine", "function" or "procedure" which are used in non object oriented languages The Basics of Java the details of procedures to serve as a placeholder, indicating that subclasses must have concrete implementations

class method a comment at its head if the method is non-obvious equivalent to the terms "routine", "function" or "procedure" which are used in non object oriented languages static method The Basics of Java the details of procedures implementing functions such as initializing a class, or operating on the complete set of instances of a class A method that, unlike an instance method, does not execute in the context of a particular instance of a class

hook method a comment at its head if the method is non-obvious equivalent to the terms "routine", "function" or "procedure" which are used in non object oriented languages 3.7 - Basic Description of OCSF- Client Side the details of procedures A method that does nothing other than returning to its caller, but is designed to be overridden in subclasses

instance method a comment at its head if the method is non-obvious equivalent to the terms "routine", "function" or "procedure" which are used in non object oriented languages 2.4 - Methods, Operations and Polymorphism the details of procedures A method that executes in the context of a particular object; it has access to the instance variables of the given object, and can refer to the object itself using the 'this' keyword (in Java and C++)

Java method 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 comment at its head if the method is non-obvious public except for those that will definitely need to be called from outside the package its caller from only one place which should be the last statement 9.1 - The Process of Design a method in a superclass with the same name the details of procedures a special-purpose function such as the user interface for a particular system other methods and variables in any class in the same package by default if related aspects of a system are kept together in this module, and unrelated aspects are kept out

long method shorter methods a comment at its head if the method is non-obvious equivalent to the terms "routine", "function" or "procedure" which are used in non object oriented languages Programming Style Guidelines the details of procedures more than 20 lines of code

utility a domain model if you have to store or manipulate instances of it in order to implement a requirement a comment at the top describing the purpose of the class, how it should be used, its authors and its history of modification the unit of data abstraction in an object-oriented program 9.2 - Principles Leading to Good Design the pieces of data that describe some entity, so that programmers can manipulate that data as a unit to hold a responsibility if the responsibility cannot be attributed to any of the existing classes the details of data variables methods A method or class that has wide applicability to many different subsystems and is designed to be reusable a programmer to cope with the complexity of data the internals of a computer system such as 'Record', 'Table', 'Data', 'Structure', or 'Information' several similar objects 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 utility^2
