Computer Science II
Test Questions
Course Introduction
Computer Science II is a continuation of foundational programming concepts, emphasizing object-oriented design, data structures, and algorithm analysis. Students will deepen their understanding of programming languages and learn techniques for managing complexity in larger software projects, such as encapsulation, inheritance, and polymorphism. The course covers essential data structures including arrays, linked lists, stacks, queues, trees, and hash tables, alongside sorting and searching algorithms. Through hands-on projects and assignments, students will develop skills in designing, implementing, testing, and debugging robust programs, preparing them for more advanced computer science courses.
