9. Object Oriented Programming
Introduction to
Object Oriented Programming
Concepts

10. Edsger Dijkstra
The machines have become several orders of magnitude more powerful!
As long as there were no machines, programming was no problem at all;
When we had a few weak computers, programming became a mild problem, and
Now we have gigantic computers, programming has become an equally gigantic problem.

11. SOFTWARE CRISIS 60% projects had schedule overruns,
50% projects had cost overruns,
45% projects could not be used,
29% projects was never delivered, and
19% projects had to be reworked to be used.
*USA contractors surveyed

12. Object-oriented programming addresses those problem by strongly emphasizing modularity in software.
Modul is a component of a larger system, and operate within that system independently from the operations of the other components.

14. A LOOK AT PROCEDURE-ORIENTED PROGRAMMING
Main Program
Function 1
Function 8
Function 6
Function 4
Function 5
Function 3
Function 2
Function 7

15. Global Data
Function 1
Local Data
Some characteristics:
Emphasis is on doing things (algorithms)
Large programs are devided into smaller programs
known as function/ subrutin
Most of the function share global data
Data move openly around the system from function to function

16. OOP PARADIGM
DATA
FUNCTIONS
OBJECT A
OBJECT C
OBJECT B

17. BASIC CONCEPTS OF OOP OBJECTS CLASSES DATA ABSTRACTION ENCAPSULATION
INHERITANCE
POLYMORPHISM
DYNAMIC BINDING
MESSAGE PASSING

18. Some of OOP’s striking features:
Emphasis is on data rather than procedure.
Programs are divided into objects.
Data structures are designed such that they characterize the objects.
Functions are tied together in the data structures.
Data is hidden and can not be accessed by external functions.

19. CLASSES Is the user defined data types
A collection of objects of similar type
Example:
Object mango, apple, and orange is member of class fruit
Object TF, TI, TK, TP is member of class Jurusan
Object jip, sedan, bus, truk is member of class mobil

20. OBJECTS Is the variables of program
Have a life cycle. They can be created and destroyed.
Interacts by sending message to one another
Contains data and code/ function to manipulate the data

21. Representing notations:
Object: STUDENT
DATA:
Name
Date-of-Birth
Marks ….
FUNCTIONS:
Total
Average
Display
STUDENT

22. DATA ABSTRACTION
The act of representing essential features without including the background details or explanations.
Defined as list of attributes and functions.
Known as Abstract Data Types (ADT).

23. ENCAPSULATION
Wrapping up of data and functions into a single unit (called class).
The data is not accessible to the outside world and only functions which are wrapped in the class can access it.
Insulation of the data from direct access by the program is called data hiding

24. INHERITANCE
Is the process by which objects of one class acquire the properties of objects of another class.
Supports the concepts of hierarchical classification.
Provides the idea of reusability.
Example: the bird robin is a part of the class flying bird which is again a part of the class bird.

25. Bird
Attributes:
Feathers
Lay eggs
Flying Bird
_________
Non Flying Bird
Robin
Swallow
Penguin
Kiwi

26. POLYMORPHISM The ability to take more than one form.
An operation may exhibit different behaviour in different instances depends upon the data types used in the operation.
Example: addition operation
If two numbers, will generate a sum
If two strings, will generate a concatenation
Extensively used in implementing inheritance

27. Shape
Draw ( )
Box Object
Triangle Object
Circle Object

28. DYNAMIC BINDING
The code asociated with a given procedure call is not known until the time of the call at run time.
Associated with polymorphism and inheritance.
Example: (above diagram) Unique to each object and so the draw procedure will be redefined in each class that defines the object.
At run-time, the code matching the object under current reference will be called.

29. MESSAGE PASSING
Object oriented program consist of a set of objects communicate with each.
Steps:
Creating classes that define objects and their behaviour.
Creating objects from class definitions.
Establishing communication among objects.
Objects communicate with one another by sending and receiving information.
Message passing involves: object’s name, function’s name (message) and information

30. BENEFITS OF OOP
Through inheritance, we can eliminate redundant code and extend the use of existing classes.
The principle of data hiding helps the programmer to build secure programs.
Can be easily upgraded from small to large systems.
Software complexity can be easily managed.
