Chapter 20 Further Programming

a set of programming concepts

programming instructions that use the computer's basic instruction set

programming paradigm in which the steps required to execute a program are set out in order in the order they need to be carried out

a programming methodology that uses self-contained objects, which contain programming statements(methods) and data, and which communicate with eachother

a template defining the methods and data of a certain type of object

the data items in a class

a programmed procedure that is defined as part of a class

process of putting data and methods together as a single unit, a class

an instance of a class that is self-contained and includes data and methods

data and methods within an object that perform a named action

an occurance of an object during the execution of a program

technique which protects the integrity of an object by restricting access to the data and methods within that object

process in which the methods and data from one class, a superclass or base class, are copied to another class, a derived class

feature of OOP that allows methods to be redefined for derived classes

feature of OOP that allows a method to be defined more than once in a class, so it can be used in different situations

process by which one class can contain other classes

a method that gets the value of a property

a method used to control changes to a variable

a method used to initialise a new object

a method that is automatically invoked when an object is destroyed

statements of facts and rules together with a mechanism for setting goals in the form of a query

a 'thing' that is known
