Abstract
C++ added object-oriented programming onto C. This allows the language to contain non object-oriented code and object-oriented code. Java differs in that it is completely object-oriented. This chapter discusses the main parts of object-oriented design, that is:
-
Classes. This is a collection of data and methods that operate on the data.
-
Objects. This is a created instance of a class which contains its own class data.
-
Methods. These are used to operate on objects and are equivalent to procedures (in Pascal) and functions (in C).
-
Constructors. These are used to initialise an instance of a class.
-
Method overloading. These are used to define a method which has different parameters passed to it.
-
Garbage collection. This is used to clean-up unused objects.
