This Java program must use at least 2 classes and object-oriented design (OOD) as I'm in a more advanced Java class.

(Salary Calculator) Develop a Java application that determines the gross pay for each of three employees. The company pays straight time for the first 40 hours worked by each employee and time and a half for all hours worked in excess of 40. Youre given a list of employees, their number of hours worked last week and their hourly rates. Your program should input this information for each employee, then determine and display the employees gross pay. Use class Scanner to input the data. Also could you please use import javax.swing.JOptionPane; in this application? Thank you.

IMPORTANT NOTE!!: As stated above, this program must use classes and object-oriented design (OOD). Also, please add detailed, but brief comments to most, if not all of the code to explain what is being used in the code and what is does so I have a better understanding of the code.

For example:

// Condition to check the price is less than zero or not.

if (price < 0)

Again, thank you! :)
