This course discusses Object-Oriented Design and Analysis.
This course focuses on the fundamental ideas that make up object-oriented programming (OOP, for short). You will design a simple object oriented program according to object-oriented principles and learn how to document your
object oriented designs using uml diagrams.
After completing this course, you will be able to create design specifications that demonstrate the essentials of OOP, including:
How classes allow programmers to define their own data types
How messages are passed between objects with methods
How to separate interfaces from implementation using access protection
How to guarantee that variables are initialized with constructors
How to reuse code via inheritance
How polymorphism allows the same message to be sent to different objects
In the next lesson, the prerequisites for the course including C++ and Java will be discussed.
In object-oriented programming, polymorphism refers to a programming language's ability to process objects differently depending on their data type or class. More specifically, it is the ability to redefine methods for derived classes.
For example, given a base class shape, polymorphism enables the programmer to define different area methods for any number of derived classes, such as circles, rectangles and triangles.
No matter what shape an object is, applying the area method to it will return the correct results. Polymorphism: is considered to be a requirement of any true object-oriented programming language(OOPL).
