Hello World!

Objective

This project will ensure that you have installed the course tools correctly, that you can "check out" a project, work on the project, and then submit the project. You will also learn how to see the results of your submission on our "submit server".

Getting Started

To work on a class project, the first thing you must do is to "check out" the project from your CVS repository. This was demonstrated in class, and is also described in the Eclipse Tutorial. The basic steps are:

1. Start Eclipse and go into the CVS perspective. Create a CVS connection to your account. Here is a screenshot of the "CVS Connection Dialog Box" with the correct entries for this semester. Note that in each place it says "cs131XXX" you should replace the XXX with your account number.
2. Open the connection by clicking on the little triangle next to it, then click the triangle next to the entry that says "Head" - this should reveal the files that are currently on your CVS repository.
3. Right-click the project called "Fall10Proj0" and choose "check out".
4. Go back to the Java perspective.

1. Open the Project by clicking the triangle next to it. Click the triangle next to the "default package" folder. Now open the file called "HelloWorld.java" by double-clicking it. This should open up the source-code in the editor on the right portion of the screen.
2. Edit the file so that it will work correctly. (It should print "Hello World!" instead of what you see inside the quotes!) Don't forget to save your work.

If you write the project from scratch, without checking out the "Fall10Proj0" files from your CVS repository, you will not be able to submit your work.

Submission

Submit your project from Eclipse (within Java perspective) by right-clicking the project folder and selecting "submit" . When it asks for your ID and password, be sure to use your University of Maryland "Directory ID" and the corresponding password, and NOT your class account and password. You may submit as many times as you want -- we will always grade the submission that scores the highest on our automated testing (taking into account the late penalty for any submissions that were after the deadline, but not more than 24 hours late. The penalty for late submissions is 20%.)   After you have submitted your project, you should visit the submit server.  There you can obtain limited feedback about how well your project is performing.  The number of times you can run our tests on your project (before the due date) is limited.  The earlier you begin working on the project, the more opportunities you will have to see how your project performs on our tests before the due date!

Grading

There is just one release tests which will be run on your project.  If you pass this test, you will receive a grade of 100% on the project (and if you don't pass this test, your grade will be 0.)
