Java Tutorials by Dr Heinz Kabutz

In this first episode, we code a simple ArrayList in under 10 minutes in preparation for a more complicated episode 2, where we code a CircularArrayList. We use the Apache Commons Collections test cases to ensure that our code is correct.

This part 1 of 2. In the second part, we will expand this to a CircularArrayList, that allows constant time add and remove at the front of the list.
