CSE 205 Final Exam 2026/2027 is an 11-page exam-preparation resource containing 20 multiple-choice questions with provided answers. The document focuses primarily on Java object-oriented programming and core data structures and algorithms. Its Java coverage includes method overriding, inheritance, subclasses and superclasses, interfaces, interface constants, the Comparable interface, compareTo, instanceof, equals, toString, protected and private access, final classes, abstract classes, concrete classes and polymorphism-related class relationships. These questions are designed to test both conceptual understanding and the ability to recognize correct Java syntax and object-oriented programming behavior.
The algorithms section covers selection sort, Quicksort, binary search and asymptotic growth rates. Students are asked to identify how selection sort places elements, reason about elements relative to a Quicksort pivot, determine the worst-case number of elements visited during binary search on an ordered array, and correctly rank growth rates including Θ(n log n), Θ(n³/²), Θ(n³) and Θ(2ⁿ). These topics make the document particularly useful for reviewing algorithm efficiency and fundamental complexity concepts alongside Java programming.
The final portion concentrates on fundamental data structures. It reviews queue behavior and FIFO ordering, doubly linked lists and the node-reference changes involved in removing a middle node, as well as stacks and LIFO access. Together with the earlier questions on interfaces, inheritance and Comparable implementations, the material provides targeted preparation across Java OOP, searching and sorting algorithms, algorithmic complexity, and commonly tested linear data structures.
Relevant students: CSE 205 students preparing for the final exam, Java programming students, computer science and software engineering undergraduates, students studying object-oriented programming, and learners reviewing inheritance, interfaces, sorting and searching algorithms, Big-O/Theta complexity, linked lists, queues and stacks. The uploaded document identifies the course code as CSE 205 but does not state a university or instructor, so an institution name should not be invented.
