COM1204 Spring 2001 -- Quizzes and Exams

THE FINAL EXAM

Here is a page about the Final Exam which includes a link to the answers to the Midterm.

Important note on what we'll be doing to finish up this quarter (also on course homepage)

After the Midterm, we will concentrate exclusively on the Project design and implementation. The students, Professor Futrelle and Ms. Shan all need to focus all their course time on the projects in an effort to bring it all to a proper conclusion. There will be no additional material from the book to study. I will update the Syllabus to reflect this schedule. But there may be aspects of the Java language that arise as we study the system design and implementations that you are doing. I will go over these and hold you responsible for them in your coding and especially, on the Final Exam. There will be a Final Exam. Sadly, there are students who get fairly far through their CCS major with little experience and skill in writing programs. This simply won't do. It is vitally important that you be able to sit down with a piece of paper in front of you and write basic code in at least one computer language. You need to be able to read and understand code too. After the Midterm on the 17th, there are only two weeks of classes left, five class meetings (Monday the 28th is the Memorial Day holiday). This is the time period in which you can focus exclusively on your project. It will be important for you to come to these last five classes, where you'll learn about aspects of Java you'll need to know as well as final guidelines for your project work as well as details about the Final exam.

NEW! Details on the Midterm Exam with partial questions

In this Midterm Exam Outline, I have furnished you six questions that are very close to what will be on the two Midterms (Red and Blue). I have omitted certain critical parts of the questions, the important details you'll see when you take the test. But I've added additional notes to give you some idea of what the details will include and therefore, what you should study for. You will have to both read and understand and write code on the Midterm and the Final Exams. So learn your Java! The only way to prepare for a test in which you have to write code on paper is to write code on paper! So practice writing Java code. The Midterm is a one hour test that will be given on Thursday the 17th.

Quiz #1 -- Now on Thursday 3 May 2001

The quiz was given and here are the answers, in some detail.

This will be an approximately 30 minute quiz based primarily on material in your textbook, similar to the Assignment #2 homework, with questions selected from the following topics.

• Sec. 2.3 on objects and variables, including arguments in method calls.



• Sec. 2.6.1 on Integers and 2.6.2 on Vectors.



• HelloWorld on pg. 34 -- be able to explain all parts of it, e.g., static, String[], etc. Also in the Java Tutorial here.



• Visibility or access specifiers, pgs. 17 and 93. Also in the Java Tutorial in this section.



• Understand specification using REQUIRES, MODIFIES and EFFECTS, Fig. 3.2 and discussions in Chap. 3. For example, given source code such as in Fig. 5.6 but without the specifications, be able to write correct specifications.



• Records, esp. Fig. 5.9.



• Be able to write a toString() method for a record. Sec. 5.4. There are 10 entries in the book's index to toString(). An example is in Fig. 5.11.



• Discuss "exposing the rep" both via visibility and returning items from non-public members. (There's also the problem of a class not storing a clone of an object given it.)



• For classes, just some basics from Chap. 7. For example
  • You can write IntSet iset = (IntSet) new MaxIntSet();
  • but not MaxIntSet miset = (MaxIntSet) new IntSet();
  To understand this, consider the use of the max() method on iset versus miset.



• Since you have been implementing in Java as part of your work, there may also be a question on the quiz that involves writing a small piece of Java code.
