Object-Oriented Programming Exam Solutions
Course Introduction
Object-Oriented Programming introduces students to the fundamental principles and techniques of object-oriented software development. The course covers concepts such as classes, objects, inheritance, polymorphism, encapsulation, and abstraction, enabling students to design and implement modular, reusable, and maintainable code. Emphasis is placed on solving real-world problems by modeling them as interacting objects, utilizing appropriate design patterns, and applying best practices in object-oriented analysis and design. Students will gain hands-on experience through programming assignments and projects using a modern object-oriented language such as Java or C++.
