To everyone ...

We will meet in the Linux Lab on Friday to start the sequence assignment.
Before lab, you should copy the entire directory from
   ~katz162/link162/seqA
and create a new Java project.

At the start of that in-lab activity, we will have a short, closed-notes
quiz concerning the activity. You should be able to describe the abstract
view of the sequence as well as the representation we are using in this
implementation. There will be other questions to assess whether you're
prepared to start the assignment. But you don't have to memorize the method
names or the class invariant. You should be familiar with what we'll be
doing in the lab activity. Understanding System.arraycopy (p. 126) is also
a good idea. The quiz counts as 25 in-class points. The sequence assignment
counts as 100 extended points.

Dr. Liffick pointed out that the textbook is inconsistent. It uses the
method name of concatenation in the book but catenation in the code. I
just changed the code and Javadoc to use concatenation.

If you were working ahead (a good thing) and had copied the files already,
you need to change the DoubleArraySeq.java and TestDoubleArraySeq.java
files to have con in front of catenation. 

I've written a description of short JUnit test cases you can add to your
TestDoubleArraySeq.java to try to detect bugs in the constructors. It's at: 
    http://cs.millersville.edu/~katz/cs162/junit/seqAconstruct
Reading that is not essential to your understanding of this assignment.
But it will help you gradually understand JUnit and testing.

See you Friday.

Ms. Katz
