CST 8284 Object Oriented Programming I

Assignment #3

Purpose Demonstrate use of:

•    Swing components to build GUI application.

• “secure” random numbers

•    good class construction including packages, Javadoc & comments

Task simulate a multi-sided die and “roll” it to obtain random values

Detailed requirements:

•    Create a Swing GUI application that simulates a multi-sided die.

•    The end-user can set the number of sides. They enter the value in a JTextField.

o If this value less or equal to zero, create a popup error JOptionPane with an appropriate message.

o Similarly, if the end-user enters anything other than a numeric value, create a popup error JOptionPane with an appropriate message.

•    Once the number of sides is determined, the end-user can simulate rolling the die   by pressing the button at the bottom of the application screen (See Sample Output below.)

o The end-user can click this button multiple times. On each click a new value for the die is shown in read-only JTextField.

o The value is randomly generated. The smallest value is 1 and the largest is the number of sides previously specified.

o Be sure to use the SecureRandom class when generating the random values.

•    Implement the handlers as anonymous inner classes (for full marks).

o Other implementations will be given partial marks.

•    Application must compile in order to receive marks

o Submissions which do not compile with receive an automatic zero

•    Be sure to include Javadoc comments for all public classes and methods. Also be sure to write appropriate comments

•    Hints:

o Refer to the code examples from the Theory Lecture in Week 11

e.g. launch3, tempConverter and those demonstrating buttons and handlers

o The font used for the labels and text-fields is: 24 pt “plain” Tahoma

Sample Output:

•    For full marks, your implementation must use the same components and same alignments as shown below.

Coding requirements:

•    follow the Java Coding Conventions as your "style guide"

•    name of the class with the main() method must end in "Test"

•    create an Eclipse project

o be sure to name your project Lastname.Firstname.Assign3

o example: Flintstone.Fred.Assign3

•    similarly, export your Eclipse project as a .zip following these naming conventions:

o name your file Lastname.Firstname.Assign3.zip

o example: Flintstone.Fred.Assign3.zip Note:

•    You will lose marks if you do not:

o follow the instructions under Detailed Requirements

including any algorithms described

o meet the Coding requirements

o produce the same output as the Sample output
