Assignment 1 A Tokimon is a rare creature

CMPT 213 Assignment 1
.
Overview
A Tokimon is a rare creature found in the remote areas of Korea. For the most part, they
resemble rabbits and the only form of communication they have with us is the ability to say
their own name. Tokimons come in all shapes and sizes, have special abilities, and tend to fight
with each other on occasion. Each Tokimon could have the ability to fly, fight, throw fire, spray
water, electrify, and freeze other Tokimons; their strength is measured by an integer between 0
and 100. Because they are such primitive creatures but have such extraordinary abilities, they
must be tracked.
Technical Requirements : Create a new project.
You must (at least) have the following classes:
- A class to hold Tokimon information: name(String), size(double), ability/type(String),
strength(integer); you are free to add more :). The name may be more than one word (i.e.
“Bobby Chan”). The class must properly implement the toString() method as discussed in
class.
- A helper class for displaying a menu prompt to the user.
o Pass the constructor the menu's title (String), and menu's options (array of Strings).
The options should not include numbers ([give the name]).
o Method which prints the menu (title and numbered menu options ) to the screen.
Automatically place a rectangle of *'s around the menu's title, sizing the rectangle
to the length of the title. Automatically number the options starting at 1.
o Method to prompt the user to enter a selection from the menu. When there's an
error (invalid value) the method re-ask the user for a value. You may assume user
always enters correct type of data: when asked for an int, it is OK if the program
crashes when the user enters a non-int such as ‘A’.
- A class for the main application. Contains a main() method which uses the menu and Tokimon
classes to implement the application. Create an ArrayList of Tokimons to hold the set of
Tokimons the user enters. Be careful not to have much duplicate code in your application!
Use functions.
Your code must conform to the programming style guide (available in the resources section of
the course website). All classes must have class-level JavaDoc comments describing the purpose
of the class.
- Text Interface: your app should have the following general options to choose from:
1. List all Tokimons including the name, height, ability and strength
2. Add a new Tokimon. Prompt the user for a name, type, height, and ability. By default,
new Tokimons will have strength 0.
3. Delete a Tokimon. First list all current Tokimons, allow the user to choose the Tokimon
to delete (or 0 to cancel). Entering an invalid number should be handled by the
program, but invalid datatypes such as ‘A’ need not be handled.
4. Augment strength. First list all current Tokimons, allow the user to choose the Tokimon
to increase the strength, then prompt for the amount. Once again, you do not need to
handle invalid datatypes.
5. Display the toString() on each Tokimon in the system.
6. Exit the program.
Here is some sample output, you do not have to match the exact layout (it’s just a
suggestion):

BYE!
You may assume any requirements that are not explicitly stated in this description (within
reason). If you’re not sure of a requirement, please see the TA or myself.
Marking Scheme:
[20] Basic Functionality
[5] Robust keyboard input: when given a number out of range it asks for retry.
(Not testing typing text, like "A", instead of a number).
[5] Able to add and remove Tokimons.
[5] Able to augment strengths correctly.
[5] Good listing of Tokimons, and debug listing (using toString).
[10] Code Quality and Style Guide
* Reasonable object oriented structure
* JavaDoc comment on each class (not needed on methods/fields)
* Correct indentation, brackets, spacing (use IDE's reformat if needed).
* Good intention revealing class, method, and variable names.
