Requirements

For this program you will be asked to write a simple data management program. Start by choosing what sort of thing you would like to keep track of. For example,

Student information

Vacation or travel information

Information about courses

Plants

Pets

Food

Your program will manage your data collection. We will start with the simplest collection of data, a list. Your list will contain the Things of your choice.

Requirements for YourChoiceOfThing Class

Implement the sort of Thing to be stored as a class. The object/class must have the following characteristics:

At least 5 attributes/characteristics

At least one numeric attribute

At least one String attribute

One String attribute should be usable as a search key (for example, the name of a Food item)

Implement getters and setters for all the attributes of your Thing of choice.

Implement an equals() method for your Thing class.

Requirements for the CollectionOfYourThings Class

Create a collection of Things using an array. You may NOT use the library classes ArrayList or Vector.

Implement a constructor which accepts as an argument the maximum size of the data collection.

Implement a search method which returns a single object.

Implement an add, update, delete methods.

User Interface Class

Use the user interface class provided for you in class. A soft copy is available for download from D2L.

Alter the user interface class to use YOUR classes. Change the names of the classes to reflect your item of interest.

Allow the user to:

Enter data and store it in the list.

Update an entry in the list

Delete an entry from the list

Search for an item in the list.

Duplicates should not be allowed.

Display the complete list. The list which is displayed should accurately reflect the items stored in the data structure. That is, if an item is updated or deleted, the list which is displayed should show that.

Given a search key by the user, search your list for a matching object. Retrieve and display all information for the matching object. The search key should be CASE INSENSITIVE. For example, ITEM should be a match for item or IteM. Your search key must be a string, not a number.

Display the number of items in the list.

Use of a graphical user interface such as swing is required.

Grading Criteria

Methods must be of appropriate length usually less than 1 page in length

Appropriate private and public access modifiers must be used. Almost always data is private and methods are public although you may certainly have private or protected methods if appropriate.

User interface is intuitive and easy to use.

Meets program specifications as described above

The program is robust with no runtime errors or problems

Program is readable

Comments

Use Javadocs conventions (Appendix H)

Include comments on the class as a whole including

Description of program

Your name (use @author)

Date (due or date you started or last modified)

Source of any borrowed code

For each method include

Concise description of what method does

Arguments for each method (use @param)

Returned value (use @returns)

Exceptions which are thrown (@throws)

Consistent and correct indenting

Meaningful identifiers

Normal capitalization conventions are used

The source of any "borrowed" code is clearly identified
