fundamental OOD concepts like Classes and Objects Think of classes as blueprints for creating objects Objects are instances of these classes possessing specific data and behaviors For example a Car class can be used to create multiple Car objects eg a red sports car a blue sedan Encapsulation Imagine protecting important data within a capsule Encapsulation hides internal implementation details from the outside world making the code more robust and easier to maintain A BankAccount class could encapsulate account balance and transaction details hiding the internal implementation of balancing from the user Inheritance This powerful mechanism allows creating new classes child classes based on existing ones parent classes This creates a hierarchical structure and promotes code reuse A SportsCar class can inherit attributes and behaviors from a Car class Polymorphism This enables objects of different classes to respond to the same method call in 2 their own unique way This leads to flexible code that can adapt to various situations Both a Sedan and a Truck can have a start method but their implementation might differ Practical Examples and HowTos Lets illustrate with a simple example designing a Library system 1 Identifying Classes Book Contains title author ISBN availability Member Contains member ID name borrowed books Librarian Contains librarian ID name tasks like addingremoving books 2 Defining Relationships A Member can borrow Books A Librarian manages Books and Members 3 Creating Class Diagrams Visual representation of class relationships attributes and methods could be included here a UML diagram showing the Book Member and Librarian classes their attributes and relationships HowTo Designing a Customer Account System 1 Identify Classes Customer Account Transaction 2 Define Attributes Customer name address phone Account account number balance type Transaction transaction ID amount date 3 Establish Relationships A Customer can have multiple Accounts and Accounts have Transactions 4 Implement Methods Customer methods for adding accounts logging in Account methods for depositing withdrawing Transaction methods for recording retrieving
