Object-Oriented Programming Exam Practice Tests
Course Introduction
Object-Oriented Programming introduces students to the fundamental concepts and principles of programming using the object-oriented paradigm. The course covers essential topics such as classes, objects, inheritance, encapsulation, polymorphism, and abstraction. Students will learn to design and implement software solutions by modeling real-world entities as objects and establishing relationships among them. Through hands-on projects and coding exercises, participants will develop problem-solving skills and gain proficiency in an object-oriented programming language, preparing them for advanced software development and engineering tasks.
