Problem Description
Wombat Corporation needs a GUI program to calculate how much to pay their hourly employees each week. The US Department of Labor requires that employees get paid time and a half for any hours over 40 they work in a single week. For example, if an employee works 45 hours, they get 5 hours of overtime, at 1.5 times their base pay.
Specifications
Write a program that will allow users to enter an Employee’s ID Number, Base Pay amount, and the Hours Worked for a particular week. This information will be added to a list of employees showing the entered information and the paycheck amount.
Use a Border Pane for your program.
The Center Region is where the table of information will be displayed. Use a GridPane to make it easier to line up the columns.
The Top Region contains fields for the user to enter employee data and an Add button. Pressing Add to insert the information into the table in the Center Region.
The Bottom Region should have a field containing the total Pay Amt for all entries. For the example above, an amount of $1,275.81 would be displayed.
The Right Region should have 4 vertical Radio Buttons labeled Raises. The 4 buttons should be labeled, from top to bottom, 1%, 2%, 5%, and Reset. If the user selects any of the first 3 buttons, you will need to increase each Pay Amount by that percentage.
So the screen would look something like this after a couple of entries:
(Note: This is an example. You are not required to make your output look like this.)
If the user pressed the 5% Radio Button, the example above would look like:
If the user clicks Reset, the amounts go back to their original values.
Hint: Store the values entered in an Array or ArrayList and rebuild the GridPane accordingly.
Error Checking
Inputs
Make sure all fields are numbers.
Hours Worked should not be less than 4.
All fields need to be correct when the Add button is pressed.
Use a Try-Catch blocks where you deem appropriate.
Explanation / Answer
Due to lack of time I could not implement the raises functionality. Rest works
