In light of today’s events at the Boston Marathon, we’d like to make the following adjustments to course projects since we know many people were not able to work today and may have limited availability over the next few days:

• code reviews are not mandatory, but will be offered to those who are ready

• project with sound is optional

• those who cannot present will be graded on the work done by Wednesday deadline only

Please contact me and Prof. Proulx if you have any questions.

Submission details - please, read:

• To fix the problem with IValue class, please, rename the ILo.java file to IValue.java

  I re-used an older assignment and did not rename the files to conform to Java requirements of matching the file name with the first class or interface defined within.

• Ignore the problems with InFileCityTraversal, NoSuchElementException and USMap files - we will add those points to the grade.

• Rename the file (and the class within) TestCity.java to CityTest.java so it would run the JUnit tests within.

• After that, worry only about the problems caused by your own code.

Something went terribly wrong with WebCAT while I was teaching tonight. It seemed to have been fixed shortly before midnight.

The homework submission deadline for assignment 6 has been extended till 4:00 pm on Friday, February 22nd.

I will check with systems if they had some problems - as I know my internet connection on CS Xnet went down in the mid-afternoon on Thursday.

=================================================================

Wed Feb 13 11:27:51 EST 2013

Every pair has to meet with an instructor, a TA, or a tutor to review their game design submitted for assignment 4.

Sign-up sheet is posted on David Van Horn’s office door (350 WVH)

Both partners must attend the review.

If your submission was incomplete, please email the remaining parts to the reviewer well ahead of the scheduled meeting time (this includes images, design documents, user’s guides, as well as a code that compiles and runs).

=================================================================

I did not specify the type of Exception you should throw in the second problem (BoundedPt). Please, use RuntimeException.

Some of you have already submitted, matching my original IllegealArgumentException. If your submission is complete and passed all tests, leave it.

If you are making changes to your submission and resubmit, you will need to change this to

RuntimeException

Here is a copy of questions a student asked - and my response. I think all of you may find it helpful.

When submitting to Web-Cat, it is currently expecting us to write tests the method in the GameRunner, which, as far as I understood, was essentially a copy and paste job with minor changes from the AppleOrchardRunner file. Is this a mistake, or if not, how are we supposed to write tests for them?

I am not sure what you are saying here. GameRunner only has the code the actually runs the game - not the code that tests the individual methods. The method tests are still in Examples... class.

Also, I am having a slight issue with other testing in my program. I have a method that involves an object reappearing at a random x coordinate and a set y coordinate after hitting the ground, and this is applied on both a single object and list of said object. How should I do tests for it? I read the information posted the website’s blog and even with checkRange, I’m failing to see how to pull it off, at least in order for Web-Cat to accept it as a valid test for the methods.

For a single object you could check that the y=coordinate of the object is within the expected range.

To design proper tests for the list of objects, you would need some of the techniques we are just now covering in class. If you could make an example with only two or three of these objects and test that at least the first (or all three) are within the given range it would solve the problem.

You are asking the right questions and learning valuable lessons as you do so.

=================================================================

To generate random numbers for your game:

// add to your imports the following

import java.util.*;

// define in the class where you need a random number:

// a random number generator

public Random rand = new Random();

// when you need a random integer in the range from 0 to 4

// just write:

rand.nextInt(5)

To test the results use either checkOneOf or checkRange test methods. See the documentation for samples and examples at the tester library User’s Guide

Assignment 3 submissions instructions

Your HW3.zip file should contain the following files:

• WP.java - a file that contains all class definitions and interface definitions for the first problem (web pages).

  It should define the class or interface WP

• WP.txt or WP.docx or WP.pdf or WP.png (or some other image format) - a file that contains the class diagram for the first problem (web pages).

• IMobile.java - a file that defines the IMobile interface and all classes that implement it.

• ExamplesWP.java - a file that contains sample data and tests for the web pages problem.

• ExamplesMobiles.java - a file that contains sample data and tests for the mobiles problem.

• pairxxx.txt - a log file for your pair.

Special instructions:

• The Examples file no longer need to use public when defining the Examples... class, and the class does not need to include the default constructor.

• The names of the classes and interfaces in the web page problem should be:

  • WP - the class that defines a web page

  • Item - the class that defines an item on a web page

  • Text - the class that defines a text item on a web page

  • Image - the class that defines an image item on a web page

  • Link - the class that defines a link item on a web page

  • ILoI, MtLoI, ConsLoI - the classes and the interface that define a list of items on a web page

• Use the file DrawingMobiles.java (i.e. the code provided with the assignment) to check that your mobile drawing looks correct, but do not include this file in your submission.

• Important! Before submitting the final version comment out the method drawAt for the interface IMobile and the classes that implement the interface.

  Otherwise, the grading system will deduct points for not having tests for these methods, and there are no meaningful tests we can design other than verifying that the images display correctly.

  The graders will check the correctness of these methods.

=================================================================

Assignment 3 update

I have posted the instructions for how to design the display of the mobile, how you can show the display, as well as links to documentation for image drawing library.

We will work with this library during the lab on Tuesday.

Do not submit the file that shows the mobile with your homework - it will fail if you do so, as it has no place where to show the images.

=================================================================

Tue Jan 22 11:15:24 EST 2013

Correction to Assignment 2 part 1:

The name of the test instance should be jenLink:

// making sure the code contains at least one test

boolean testAll(Tester t) {

ExamplesPhoneChain epc = new ExamplesPhoneChain();

return t.checkExpect(epc.jenLink, epc.jenLink);

}
