Structured Programming an organized style of programming that places emphasis on modular programming, which aids testing, debugging and modifying. Modules are procedures and functions that process external data passed by parameters.
Object Oriented Programming style with emphasis on reliability through modular programming; Contain modules (classes), data, and subroutines (methods) that process data. OOP traits include: Encapsulation, Polymorphism, and Inheritance.
Attributes and Methods What objects in java are made up of.
Encapsulation Process of placing data structure's data (attributes) with the methods (actions) that act upon the data inside the same module, called a class in Java.
Inheritance is the process of using features (both attributes and actions) from an established higher class.
Superclass Higher class in java whose public methods and attributes/variables may be used by a class (subclass) that extends it.
Subclass Lower class in Java that extends from a Superclass -- extends meaning that the class is able to use (inherits) all public attributes/variables and public methods from the superclass.
Polymorphism Allows a single accessing feature, such as an operator, method or class identifier, to have many forms.
Class data type that encapsulates both data and the methods that act upon the data; template for the construction of objects
Object One instance of a class
Attributes/instance variables/fields The data components of a class. In the majority of classes, instance variables should only be accessed by methods of the same class.
Methods Action modules that process data. Sometimes called subroutines, procedures, or functions in other languages.Declared inside a class module -- process the instance variables
Instantiation Moment or instance that memory is allocated for a specific object of a class; Statements like 'construction', 'definition' and 'creation' of an object have the same meaning as instantiation.
constructor The special method that is called during the instantiation of a new object whose purpose is to initialize instance variables (fields/attributes); has the same identifier as the class; is neither a void nor a return method
default constructor Constructor without parameters
Private class members Can only be accessed by methods of it's own class.
Public class member Can be accessed by any client of an object x
Inner class Class declared inside another class.
