Lab #3 (Sales Tracker) - 125 Points

In our third lab of the semester we will create a Java CLI application that enables a manager to enter up to 20 salespeoples names, IDs and annual sales. Each salesperson must be anobject and must be part of one array. (No parallel arrays permitted.)

The manager can choose to add a new salesperson until there are 20 total. Once 20 salespeople are present, no new data can be added.

No duplicate IDs should be entered. Once the manager is finished, display all the salesperson data in an easy to read format.

In addition, the manager can change a salespersons annual sales by entering a salespersons ID. Make sure to check if that salesperson exists and inform the manager. After the change, re-display the list.

Please note: IDs are eight digits long and cannot be duplicated.

Lab Parameters

We need to use two separate exercises for our lab. To create the object class use the first half of Exercise 6A on pages 433-434 of the textbook. Make sure to add the salespersons name. You only need the information on constructing the Salesperson class not the DemoSalesperson application in this exercise.

After creating the Salesperson class, use Exercise 5 on page 485 of the textbook to create your application class. All parameters and logic in this section should be included, except for deleting the record. Make sure to allow for input of the salespersons name as well.

Please note the following important distinctions:

There is no actual database for this lab even though the exercises says to pretend its a database. We are working with arrays and no data will be stored between application runs.

CreateSalesperson.java:

This is the name of your main application class. The logic noted in Exercise 5 (Chapter 9) should be included here except there are no deletions.

Remember that the application class controls the programs logic.

Salseperson.java:

Your class used to create each of the 20 potential salesperson objects. Each contains a name, ID, and annual sales. This is from Exercise 6A (Chapter 8).

Make sure to add ASCII design and include your companys name and other important information in the output.

Lab Parameter Reminders:

ID must be eight characters and not a duplicate.

No parallel arrays.

Each salesperson must be an object.

Only 20 entries permitted.

If user select "add" option:

Issue an error message if the database (array) is full

Otherwise, prompt the user for an ID number

If ID number already exists in the database, issue an error message

Otherwise, prompt the user for a sales value and add the new record to the database

If user select "change" option:

Issue an error message if the database (array) is empty

Otherwise, prompt the user for an ID number

If requested record does not exist, issue an error message

Otherwise, prompt the user for a new sales value and change the sales value for the record

Do not delete the record.

Make sure to check the documentation guide and follow the directions for the header block and inline documentation.
