Object-Oriented Programming (OPP) - The Three Design Concepts

1) Encapsulation

2) Inheritance

3) Polymorphism

Class

A programming construct that describes a group of objects, thereby defining the objects’ data type

Method

A Java construct that is a part of a class and performs an action.

Defined either a behavior of an object of the class or an action of the class itself

Behavior

An action that an object can take

Encapsulation

One of the design principles of object oriented programming.

Encloses data and methods within a class, thereby hiding the details of the class’s implementation

• Hides “fine details”

• Also called Information Hiding

Information Hiding

A technique that involves hiding a class’s implementation details from its client

Class Definition

The Java statements that define a class, including data fields and methods

Abstraction

A process that focuses on what a class or method should do instead of how it will accomplish it

Data Abstraction

A design principle that separates the operations that can be performed on a collection of data from the implementation of the operations

Interface

(Client Interface)

(Java Interface)

Implementation

A class definition or a method definition

Client

The code that uses a class
