_Programming in Java
Homework/Lab Assignment 4
For this assignment, you will be completing your next project. Your project must be created in Eclipse editor and it should reflect the documentation that you turned in.
Problem Description
SAC, Inc pays its employees monthly based on a combination of base pay plus commission. The base pay is determined by the years of service in the company, per the table below:
Years of Service Base Pay
<1 $1,000
1-3 (less than 3) $1,200
3-5 (less than 5) $1,500
5+ $1,700
The commission is based on the gross sales made by the employee that month, per the table below:
Sales Commission Rate (% of Sales)
$0 - $20,000 1%
$20,001 - $30,000 2%
$30,000+ 3%
The company wants you to create a GUI application that will accept the employee’s name, the years of service, and gross sales amount and display the Base Pay, Commission Amount and %, and the Total Gross Pay for the employee, which is Base Pay plus Commission Amount. In addition, you will need to accumulate these values in order to display grand totals.
Input
• Employee name
• Years of service (whole numbers)
• Gross sales (decimal number)
• Three buttons: one for calculating and displaying the gross sales for the employee, one to clear out all input text fields (not the text area), and one for displaying the summary totals.
Processing
Use a GUI JFrame application that displays all of the components to the user in a professional, easily read layout. Use the size of individual components and the overall size of the JFrame to help align items cleanly. At the top of the JFrame, include a label containing the company name and somewhere in the panel another label with your name as the programmer displayed. You may use font size to help with the layout.
When the calculate button is pressed, complete the following:
• Validate the name to make sure that something has been entered. If the user has not entered anything into the name field, send a message using the JOptionPane class and reposition the insertion point in the name text field. Also, verify that numeric fields actually have valid numbers entered using try and catch for exceptions. (Do NOT do any calculations if any data is missing or numeric fields have errors).
• Calculate the gross pay, which is the base pay plus the commission amount.
• Accumulate totals of sales, base pay, commission and total salary.
• Display name, sales, base pay, commission amount and percent, and total as shown under Output. Display this in the text area.
When the clear button is pressed, complete the following:
• clear out all input text field data and reposition the insertion point (cursor) in the first text field.
When the summary button is pressed, display the following in a JOptionPane message box:
• display the accumulated Sales, Base Pay, Commission, and Total in a JOptionPane. Make sure that the message in the JOptionPane is formatted so that the information is easily read.
Output
• Display the output from the calculation button processing in a columnar format in a text area as follows. Notice that both the commission amount and percentage are required in the display. Use the format method discussed in class to line up the numbers (and column headings) so that they are right-aligned.
Name Sales Base Pay Commission Total
Joe Bloe $25,000.00 $1,000.00 $500.00 (2%) $1,500.00
Sally Smith $15,000.00 $1,500.00 $150.00 (1%) $1,650.00
Additional Requirements
• Use try/catch blocks to catch bad input for numeric fields
• Make sure that your text area has scroll bars so that data will not be inaccessible as additional lines get displayed
• Use constants wherever appropriate. At a minimum, consider using them for the commission percentages and the base pay values.
• Display the company name and your name as programmer in labels on the GUI.
• Reposition the insertion point into the first text field when the clear button is pressed (and only when this button is pressed).
• Make the GUI look professional and easy to read.
• Use correct naming conventions in your program. Indent the program source code correctly, leaving blank lines where appropriate. Include the recommended remarks in the Java source code., and include a both a Java Class Diagram and pseudocode of each method as documentation. Also make sure that you fill out the top portion of an Evaluation Sheet (named correctly) and include that as part of your documentation.
