Java - Programming Environment

Objectives:

• Analyse a simple data processing problem to correctly identify the data and high-level processing involved.

• Apply the basic programming construct of selection to develop pseudocode that solves simple data processing problems

• Use appropriate programming tools to develop an effective computer program from pseudocode

• Specify and execute test plans for pseudocode and programming code

• Develop external documentation for the process of converting a simple data processing problem into a computer program

• Internally document a computer program with appropriate comments.

Task 1: Pseudocode

Write a pseudocode for the Ticketing Program that will allow a user to buy multiple tickets across different ticket categories, and then display a summary of what they have purchased.

In greater detail you will need to create a program that will:

• Ask the user to select a category of tickets to purchase

• Ask the user to enter the number of tickets to be purchased

• Display a summary message regarding the number of tickets to be purchased

• Ask the user to confirm the purchase by pressing ‘Y' (If they do not wish to confirm, the program should return to the Main Menu)

• The program should display the total amount for the number of tickets purchased through the selected category

• The program should then ask if the user wishes to purchase tickets from another category

? If Yes, then the program should return to the Main Menu, with a summary of what they have purchased underneath.

? If No, the user should be given an overall summary of what they have purchased in all categories, including a grand total, and the program should then exit

Figure1 below shows an example of the expected program output

Task 2: Data dictionary

Write a Data dictionary for the corresponding pseudocode written in Task 1.

You should enter at least 10 variables.

Variable name	Type	Length	Acceptable	Description
			values

Task 3: Desk check

Desk-check the pseudo code written in Task 1 using at least two test datasets. Provide both the test data table and desk-check table.

Use the template given below to complete your answer.

Test data table:

			Input				Expected Total
First		Variable		Value		Variable			Value
dataset
Second		Variable		Value		Variable			Value
dataset
Desk check table:
Line			Variables						Input/Output
Number
1
2
3
4
5
6

Task 4: Programming

Write a program based on the pseudocode and data dictionary you designed in Task 1 and Task 2

• The program should match the logic specified in the pseudo code.

• The code should be easy to read and understand.

• The code should be well formatted.

• The program should use meaningful variable names

• The code should be well documented. This should include comments about the program: program name, purpose, author; comments describing each variable and comments on each section of the program.

Task 5: Testing

Test the program by providing screen shot using the following test data:

• Child: Number of tickets = 5
• Adult: Number of tickets = 10
• Senior: Number of tickets = 2
