    Exam #2



    Wed, Apr 06


    Q&A for the second exam.
    Come with questions.

    Exam covers all material up to the end of chapter 10 (concnetrate on chapters 8-10 and topics that we discussed in class, but you should be familiar with all of the material from the chapters).

    Topics to concentrate on:
    • 2D arrays: creation, initialization, processing (types of operations comparable to the matrix manipulation homework)
    • objects and classes:
      • definitions (+ all oop vocabulary)
      • creation, initialization of objecects
      • constructors, overloading constructors
      • public vs. private
      • static vs. instance
      • data fields and their use (accessing from within and from outside of the class, initial values)
      • methods within the class
      • use of getters and setters
      • scope of variables (data fields, local variables defined within methods, method parameters, constructor parameters, ...)
      • use of this reference
      • defining and using toString method
      • defining and using equalsmethod
    • working with arrays of objects: all kinds of operations
    • Stack class operations, implementation, use
    • work on posted practice problems
    • work on CheckPoint questions in the book (solutions are on the publishers website)
    • review (and make sure you know) the key terms at the end of the chapters
    • review chapter summaries (they are full of good vocabulary and concepts)
    • the publisher's website had additional quizzes and other materials that can help you study
    • review worksheets
