Please solve the java program

For this assignment you will create a program that determines the weekly gross pay for three

separate types of employees $($HourlyEmp$,$ SalaryEmp, and CommEmp$).$ Name the project

firstNameProgram$3($replace firstName with your first name$).$ The package name should be

your lastName in lowercase letters, followed by a period and your first initial $($also lowercase

i$.$e$.$ thomas.h$).$ The main should be called Program$3.$

You will have three classes HourlyEmp, SalaryEmp, and CommEmp. All three classes should

have string variables $($input may include spaces$)$ for firstName, lastName, and idNumber. All

three classes should also have a double variable for weeklyPay. The three classes must have a

getWeeklyPay method that returns the calculated value weeklyPay. There should NOT be a

method called setWeeklyPay $($weeklyPay is calculated based on the type of employee it is not a

value entered by the user$).$

Hourly employees are paid based on the number of hours worked, the hourly pay rate and any

overtime over $40$ hours is usually paid at time and a half or double time. The information

should all be obtained from the user. Salary employees are paid at a rate of $1/52$ of their annual

pay. Commission employees are paid at $12\mathrm{.}5\%$ of their gross sales for the week. The math

should take place inside of the getWeeklyPay method in the classes. The method will return the

result of the calculation when it is called from the main program.

The HourlyEmp class should also have double variables for hourlyPay, hoursWorked, and

otRate and an integer constant called HOURS $=40.$ The SalaryEmp class should have the three

String variables as well as a double variable for salary and an integer constant called WEEKS $=$

$52.$ Finally, the CommEmp class should have a double variable called grossSales and a double

constant called COMMRATE $=0\mathrm{.}125$ in addition to the three String variables. Create the

appropriate set and get $($also called mutator and accessor$)$ methods for the class variables $($a

constant should not have set or get methods$).$

Your program will display a menu allowing the user to choose between the three types of

employees or exit. The program must repeat until the user enters four, then it should exit. See

below for an example:

Enter $1$ for an Hourly Employee:

Enter $2$ for a Salary Employee:

Enter $3$ for a Commission Employee:

Enter $4$ to Exit:

Your program should use a while loop to allow the user to keep entering choices until the user$$s

choice equals $4.$ If the user makes an incorrect entry for choice, the program should tell the

user that they made an incorrect entry and allow the user to try again. When the user enters a

choice in the correct range $($a whole number between $1$ and $3)$ the program should ask for the

first name, last name, and id number. The program should not allow the user to continue until

they enter a choice in the correct range, a whole number between $1$ and $4.$

The program should ask for the additional information needed based upon which employee

type the user chose. Use a switch $($int choice$)$ and case statements for the menu choice. For

example, if the user enters a choice of $1$ the program should also ask for employee$$s hourly rate

of pay $($hourlyPay$),$ the number of hours worked $($hoursworked$),$ and the rate of overtime pay

$($i$.$e$.1\mathrm{.}5$ or $2\mathrm{.}0,$ called otRate$).$

For all the double variables used in the program, while the user enters a number that is equal to

zero or less, your program should tell the user that they entered an incorrect number, and they

need to enter a number greater than zero. Then allow them the chance to enter another

number. Again, the user should not be allowed to continue until they enter a number greater

than zero. You must be sure that all the display of decimals are limited to two.
