Object Oriented Design Kenneth M. An abstraction More information. Low complexity As data members and functions are hidden in objects and each object handouhs a specific behavior so there is less complexity in code there will be no such situations that a functions is using some other function and that functions is using some other function.

Advantages of Encapsulation The following are handout main advantages of Encapsulation, a. In object oriented programming approach we have objects with their attributes and behaviors that are hidden from other classes, so we can say that object oriented programming follows the principle of information hiding.

Objective of this course is to make students familiar with the concepts of object oriented programming. This association can be represented with a line along an arrow head or without arrow head Kinds of Association: The ccs304 use of binary trees is for providing rapid access to data indexing, if you will.

Object Oriented Programming (CS304)

Hakimzadeh, 1 Outline Overview More information. Simplicity and clarity As all data and functions are stored in the objects so there is no data or function around in program that is not part of any object and is this way it becomes very easy to understand the purpose of each data member and function in an object.

Interfaces are necessary for object communication.

An object may have more than one interface. Everyone can easily understand an object oriented model. Both these things are part of implementation.

Virtual University of Pakistan 1. So we can say that Data and Behavior are tightly coupled inside an object and both the information structure and implementation details of its operations are hidden from the outer world.

Person 24 Virtual University of Pakistan. Gear Box in car system Consider object Gear Box in car system it has a certain structure and functionality. There are four storage.

This is where I will conduct my. In what order do we do it? What is the most important feature of Java? If there is an abstract class then hierarchy exists in the object model as there will definitely be some concrete classes as well derived from this abstract class otherwise there is no use of abstract class.

Car is also a tangible object having some characteristics attributes and behavior given below, Car State handokts Color Model Behavior operations Accelerate Start Car Change Gear We can identify Car using its registration number Examples of Intangible Objects also called as conceptual objects: Derived class will not exhibit the behaviour of base class but it is overriding behaviour of base class with its own handkuts Overriding A class may need to override the default behaviour provided by its base class Derived class overrides the behaviour of its base class.

Something conceptual that can be apprehended intellectually for example time, date and so on. This course is an introduction to objectoriented programming using the Java language. This is achieved through the concepts of encapsulation and information hiding. In object orientation we move our concentration to objects in contrast to procedural paradigm in which we simply write our code in functions and call them in our main program What is a Model?

Function Definition Includes description of the interface and the function. Abstraction Classes Inheritance Major benefits of inheritance Reuse Abstraction Handohts life objects have a lot of attributes and many kind of behaviors but most of handoust time we are interested in only that part of the objects that is related to the problem we are currently going to solve, for example in implementing a school system we don t need to take care of the personnel life of a student or a teacher as it will not effect our system in any way so we will see these objects in the perspective of school system and will ignore their other characteristics, this concept is called Abstraction.

A class primarily intended to define an instance, but can not be instantiated without additional methods. In this lecture you will learn: Classes are arranged in hierarchies sharing common More information.

Overriding is used for Specialization, Extention, Restriction, and Performance Multiple Inheritance Sometimes we want to reuse characteristics of more than one parent class, in that case we need to inherit a class from more than one classes.

Class Example 1 Consider the objects given below, Ali studies mathematics Anam studies physics Sohail studies chemistry Each one is a Student so we say these objects are instances of the Student class. It reduces the redundancy and gives us reusability, using generalization our solution becomes less complex.

Solution We can solve this problem by explicitly calling eat method from any of the parent classes in Mermaid class according to behaviour of Mermaid i. To make this website work, we log user data and share it with processors. Hakimzadeh, 1 Outline Overview. Complete the exercise in class design. There are two cases while solving diamond problem virtual inheritance and non virtual inheritance we will study these details in coming lectures 48 Virtual University of Pakistan.

Generally when we have given a certain problem description, nouns in that problem description are candidates for becoming objects of our system. Citation s listed may represent More information. List any More information. Because of growing complexity! In addition to object-oriented constructs, C supports component-oriented programming with properties, methods and events.

Interface and implementation are separated from each other to achieve Information Hiding.
