Object-Oriented Programming
Final Test Solutions
Course Introduction
Object-Oriented Programming is a fundamental computer science course that introduces students to the concepts and principles of programming using objects and classes. The course covers key topics such as encapsulation, inheritance, polymorphism, and abstraction, enabling students to design and build modular, reusable, and maintainable software applications. Through theoretical discussions, hands-on exercises, and programming projects, students will develop proficiency in an object-oriented language, understand the importance of design patterns, and gain experience implementing real-world problem solutions following best practices in software development.
