Did you remember to fill out the brief questionnaire?


Regardless of the operating system that you choose, the goal of Assignment 0 is to make sure that you can:

Frequently Asked Questions

What's a checklist? The programming assignment specifies the general programming assignment. The checklist contains supplemental information, and you are expected to read it prior to submitting your work. Some examples include: links to any preliminary code, reference solutions, a readme.txt template, hints, and frequently asked questions.

What preparation do I need to complete this assignment? Read Section 1.1 and Section 1.2 up through page 22.

It's the first week of class. Do I really need to start reading the text? Yes. Getting off to a good start will save you alot of energy in the long run. If you don't understand something, email or visit your preceptor for assistance. Don't be bashful about asking for help.

I don't understand all of the jargon in Should I drop the course? Absolutely not! We'll explain this in the first or second precept. Do the readings and bring any lingering questions to the first precept.

What's the difference between the textbook and the booksite? Reading a book and surfing the web are two different activities: This booksite is intended for your use while online (for example, while programming and while browsing the web); the textbook is for your use when initially learning new material and when reinforcing your understanding of that material (for example, when reviewing to prepare for an exam). Also, some of the booksite is still under construction, so there are gaps.

Do I have to use DrJava? No, feel free to use any development environment you like.

How should I read in user input? Use command-line arguments as specified in the assignment and described in Section 1.2. You will receive a significant deduction for not following directions. We will learn about other ways to handle input in Section 1.5.

The template readme.txt file doesn't view properly in Notepad? Use DrJava instead. Be careful to save the file as readme.txt and not as a Java file. Do not use a word document editor such as Microsoft Word which will save the file in a different format.

What's Dropbox? Dropbox is the system you will use to submit assignments. Every assignment has a link to its own dropbox. Look on the Assignments page, in the submit column. You can also go to the general dropbox page via Either way, you will need to login.

When I login, my browser asks me whether I should accept a "security certificate." How should I proceed? Accept it permanently. We need to establish a secure connection so that you can submit assignments and check grades with reasonable privacy.

When I submit, the system does not seem to accept it. Why not? Be sure the file is named The capitalization and .java extension are important. Also, be aware that DrJava creates backup files with a .java~ extension, so be sure that you don't submit these. If you use Windows, we recommend configuring your system to unhide the filetype extensions.

How do I use the "Check All Submitted Files" button? After submitting your files, click it. It will compile all your submitted files and give you feedback.
