Design, implement, test, and debug an application to compute an employee’s weekly pay. If the employee works more than 40 hours a week, the employee earns 1.5 times the basic hourly pay for any time worked over 40 hours. The program should allow the user to input the employee’s name, the number of hours worked, and the hourly rate.
The application should include a Calculate button that, when pressed, computes and displays the total pay in a label or text field. The program should allow the user to enter information for any number of employees in this manner. Include an Exit button to end the execution of the application. The program should allow the user to select the employee’s department from a menu. This can be a standard menu, radio buttons, or a JComboBox. Create your own list to populate the menu: Marketing, IT, Accounting, and so forth.

I have no clue how to do this.
