CS 368 Program 3: PACKAGES AND EXCEPTIONS
For this assignment you will make two changes to the (linked-list
version of the) List class:
Write a main function to test the new version of the nextElement
method in a (public) class named Test in the parent directory of the
The main function should include calls that cause the new exception to
be thrown, and should include code to catch and handle the exception
(e.g., first print a message saying that a bad call is about to be
made, then in the catch clause for the exception print a message
saying that the exception was thrown and caught).
The main function should also include calls to nextElement that do not
cause the exception to be thrown.
- Make the List class a public class, and
put all of your code into a package called ListPkg, in a
subdirectory called ListPkg.
- Add a public exception called NoNextElementException, and
change the nextElement method so that it throws that exception when
it has been called and hasMoreElements is false (i.e., an
attempt is made to get the current item from an empty list or
from a list in which the
current-object "pointer" has fallen off the end of the list).
What to Hand In
Upload your List code and Test.java file.
