CreatingArrays.java

TestArrayToArrayList.java

TestArrayAndArrayListSort.java

These sample programs are the same as those
seen in the LinkedList subdirectory, except
that here we are using the Java ArrayList<T>
implementation of the Java List<T> interface.
And note that TestArrayToList.java is exactly
the same in both directories.
