Object-Oriented Programming Final
Test Solutions
Course Introduction
Object-Oriented Programming is a foundational course that introduces students to the principles and practices of designing software using the object-oriented paradigm. The course covers key concepts such as classes, objects, inheritance, encapsulation, polymorphism, and abstraction. Through hands-on programming assignments and projects, students learn how to model real-world problems, construct modular and reusable code, and apply object-oriented techniques to develop maintainable applications. By the end of the course, students gain proficiency in writing well-structured software using an object-oriented programming language, preparing them for more advanced computer science topics and professional programming environments.
