Introduction
This assignment involves writing a Java application using Swing and AWT GUI
components and a Java collections data structure. They must be hand-coded by
you. If you use IntelliJ Idea or any other IDE you must not use the GUI Designer
or any similar tool. Additionally, you should not use any other external libraries
not part of the Java API. The files should contain brief comments.
WARNING AND ADVICE ABOUT POSSIBLE ACADEMIC OFFENCES
Your solutions should be your own unaided work. You can make use of any of the
programs from the CE203 lecture notes and the lab templates on Moodle. You may
use any features from the Java Standard Edition Application Programming
Interface (Jave SE API) including those not covered in CE203.
You must NOT use any third-party classes (e.g. classes that are not provided as
part of the Java SE download). If you use any other information sources, you must
clearly reference these. For more information, please see the University pages
on plagiarism and the Academic Offences Procedures.

Part 1
Write a frame-based application that allows the user to store a list of words. The
layout should be such that any buttons will be displayed at the top of the panel,
user input is provided in a text field at the bottom and any system output will be
displayed in the centre. The application should provide features and corresponding
buttons that allow the user to:
a) Add a word to the list (the word to be added is provided in a text field at the
bottom of the application).
b) Display all the words from the list that end with a specified letter (this method
should be case-insensitive, e.g. no matter whether the user input is 'A' or ‘a’, all
words ending with 'a' should be displayed)
c) Remove from the list all occurrences of a word entered in the text field.
d) Clear the list
The list may contain duplicate entries. Words may contain only letters, numbers,
and hyphens (-) and must begin with a letter.
For each action specified above an appropriate message should be displayed on the
centre panel confirming the action, e.g.
“Word ‘toast’ has been added to the list”.
An appropriate error message should be displayed if any failed action e.g.
“The string ‘12’ was not added to the list as it is not a valid word.”
The list should be implemented using an ArrayList
Part 2
A colour may be specified by its RGB value – the amount of red, green and blue it
contains. These amounts are integers between 0 and 255. For example, red is
represented by (255, 0, 0), blue by (0, 0, 255) and yellow (which is made up from
red and green) by (255, 255, 0). White is (255, 255, 255) and black is (0, 0, 0). The
Color class has a constructor with 3 arguments that allows a user to create a
Color object by providing the RGB values.
Extend the application you developed for Part 1 so that it allows the user to specify
RGB values in three additional text fields. These should be located next to the
existing text field already defined for entering words into the application.
