- 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 Abstraction Encapsulation Polymorphism Inheritance
- 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 datafrom other source. ◆Parts of the program wrapped individually without affecting each other.

- 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.
