Day 2: Object-Oriented Programming (OOP)

Topics:

• Classes and Objects
• Constructors
• Inheritance
• Encapsulation and Abstraction
• Basic Error Handling (try-catch)

Project: Library Management System

• Description: Expand on Day 1 by creating an OOP-based library system to manage books, users, and borrow/return actions.
• Core Features:
  • Create Book, User, and Library classes.
  • Use constructors to initialize books and users.
  • Implement basic inheritance (e.g., User class could be extended to Student or Teacher).
  • Use encapsulation to protect data (e.g., user ID, book details).
  • Add simple error handling for invalid inputs or operations.
