Object-Oriented Programming
Mock Exam
Course Introduction
Object-Oriented Programming introduces students to the fundamental concepts and principles of object-oriented design and development. The course covers key topics such as classes, objects, inheritance, polymorphism, encapsulation, and abstraction, while emphasizing code reusability, modularity, and maintainability. Students will apply these concepts using a modern programming language, developing practical skills in designing, implementing, and testing object-oriented software. Through hands-on assignments and projects, students gain experience solving real-world problems and understanding the advantages of object-oriented methodologies in software engineering.
