Cs8392 u1-1-oop intro
- 1. Object Oriented Programming Rajasekaran. S Assistant Professor Dept of IT Git Hub: https://github.com/rajasekaranap/CS8382-OOPS CS8382
- 2. Course Overview Unit 1 INTRODUCTION TO OOP AND JAVA FUNDAMENTALS Unit 2 INHERITANCE AND INTERFACES Unit 3 EXCEPTION HANDLING AND I/O Unit 4 MULTITHREADING AND GENERIC PROGRAMMING Unit 5 EVENT DRIVEN PROGRAMMING
- 3. What you need? A computer with java installed. A decent internet connection for your reference. Text editor of your choice. IDE eclipse preferred. A book that help’s you when you are in offline.
- 4. Object Oriented Programming It is a software design methodology. It is a software programming model that constructed based on objects. It aims to implement real world entities in programming.
- 5. OOP Languages The programming languages that follows the oops principles is known as object oriented programming languages. Keep in mind every programming language is created for a purpose. Java is on of the general purpose object oriented programming language. Languages that follows oops principles other than java. Simula, C++, Python … etc
- 6. OBJECT Object is specific instance of a class. It is often referred as a “Real world Entity”. It lives in computer memory. It has real values. Objects of the same class need not be a same. Shares similarity with attributes but differs with values.
- 7. Example of an Object Properties Methods Colour Start, Stop Transmission Type Accelerate Max Speed Change Transmission
- 8. CLASS It is template definitions of methods and variable. Class is blue print of Object. Class should be instantiated before using. It is used to describe more than one object. A class is an extensible program-code-template for creating objects. Classes are help us to create multiple objects from them.
- 9. Car Class List the differences between above cars.
- 10. 4 Principles of OOP OOPS AbstractionAbstraction EncapsulationEncapsulation PolymorphismPolymorphismInheritanceInheritance
- 11. ABSTRACTION It is used to manage the complexity of the program. Hiding unwanted information from users. Hiding internal working mechanism from user.
- 12. Abstract Car How much user must know about the car for safe operations?
- 13. ENCAPSULATION It is containment of code and data together. It is used to protect the unnecessary external access of code and data from other source. Parts of the program wrapped individually without affecting each other.
- 14. Encapsulated Car Ex : Individual System’s in a typical car. The Transmission System and Music System is independent to each other. Transmission System. Engine Speed Gear Ratio Change. Clutch On/Off. Music System. Play/Stop Album Change Source Change [AUX/CD/USB]
- 15. INHERITANCE Reuse the code. Sharing the characteristics or properties among the objects. Parent and Child Relation Support the Hierarchical classification
- 16. Inherited Car Think about similarities and differences.
- 17. POLYMORPHISM Taking more than one form. it describes the concept that objects of different types can be accessed through the same interface. Same object act’s differently according to the situation.
