EBU4201 Introductory Java Programming 2023/24
Mini Project
Task 1 [25 marks]
SuperHeroTT is a simple Graphical User Interface (GUI) application for children where they can
practise their times tables (see Figure 1).
Figure 1 - First launch of SuperHeroTT
When launched, your app should look like Figure 1 - First launch of SuperHeroTT. The drop-down
box at the top should consist of numbers from 1-12 (inclusive). The superhero image
(superhero.jpg1
) has been provided to you. The flow of the program is as follows:
1) User selects a number from the drop-down list and clicks on the Start button.
2) The label Product is replaced by a product of the form x * n where x is the selected value
from the drop-down list and n is a random number in the range 1-12 (inclusive) AND the
Start button text is changed to Next.
3) User enters their answer for the product and clicks on Next.
4) If the answer is correct, Answer is replaced by Correct; otherwise Answer is replaced by
Wrong! x * n = y where y is the correct answer. See Figure 2.
5) Regardless of the answer being right or wrong, a new product should appear AND the
answer box (i.e. text-field) should be cleared.
6) At the end of a round, i.e. after 5 product questions, the label Rating should be replaced by
You got m correct! where m is the number of correct responses AND the Next button
should change back to Start.
7) The above process can be repeated any number of times.
Note 1: If the user wishes, they can change their selection from the drop-down list during a round.
Note 2: If the user clicks Next with no text entered, there must be no run-time exceptions
generated AND the product question must not change to the next one.
Note 3: The button or image must not resize when the GUI is resized.

Figure 2 - Wrong answer
Hint: Consider using containers within containers and using layouts intelligently.
Note: All the necessary files should be placed in a directory called Task1.You can choose
whether to place the image files directly under Task1 or within a sub-directory. Whichever
approach you take, the images must be displayed on the GUI without having to move the image
files to different locations within your directory structure.
Also note that your application must run as expected from the command line on OpenJDK
21.0.2 without the markers having to alter any code, file locations etc. Otherwise, it will not
be possible to award marks for any of the functionalities.
Task 2 [15 marks]
Your second task is to enhance the application developed in Task 1, to allow the user to select
more than one multiplicand, i.e. x (of the product x * n) at the same time. The application must
still function as specified in Task 1, the only difference being that x will be one of the selected
numbers, chosen randomly, during each of the 5 questions that make up a round.
For example, say the user selected the following multiplicands: 2, 5, 6 and 12. The set of product
questions can be:
5 *12
6 * 11
2 * 1
12 * 4
2 * 10
Note 1: It is possible that not all selected multiplicands will appear in a given round.
Note 2: The program must ensure that the users select at least one multiplicand. There is no
maximum limit so users can select any number of multiplicands (up to 12).
Hint 1: Use another appropriate component in place of the drop-down list that was used in
Task 1.
Note: All the necessary files (including any reused ones from Task 1) should be placed in a
directory called Task2.
3/5
Documentation [10 marks]
Your submitted work must include:
a. Generated Javadocs (for all Java files)
b. Internal comments in your code (for all Java files)
c. User Manual. This should be no more than 2 pages and describe, in your own words, how
to run the program (both how to start and how to use it).
Note: All documentation files should be placed in a directory called Documentation.
Extra Credit [5 marks]
Extra marks from this section can be used to top up your final grade for this project. The
maximum mark you can achieve is still 50.
Further enhance your application in the following two ways:
a) Include a timer, i.e. at the end of a round, replace Answer with You took t seconds where t
is the time taken to complete the round, in seconds. See an illustrative example in Figure 3.
Figure 3 - Timer
Hint: You are provided with the Java code (TimerDemo.java) for a simple timer using
javax.swing.Timer. Make use of this code in your program.
Note: if you wish you can visually display a countdown on your GUI. Alternatively you can
simply print out to the console, similar to TimerDemo.java.
b) Set the answer box (i.e. text-field) in focus every time the user is expected to type an answer
so that they do not need to click on the answer box.
Hint: look up methods of the text-field (e.g. JTextField) class in the Java API.
Note: All the necessary files (including any reused ones from Task 1 and Task 2) should be
placed in a directory called ExtraCredit.
4/5
Important notes:
1. This is an individual piece of work.
2. All three directories must be included in a zip file. The filename must be your QM Student
Number.
3. You should design your classes properly, following object-oriented principles. E.g., do NOT
write everything in the main method, keep code repetition to a minimum (i.e., use methods),
do NOT use static methods unless there is a good reason. There will be marks allocated for
good program design.
