Write a Java application that will allow the user to calculate the gross wages of several employees using arrays of objects. It will incorporate most of the structures that we have studied in class. There will be two classes and a driver program. The two classes are an Employee class and a Sales Person class. The data members of the Employee class are name, 4 digit id number, hours worked, hourly rate and gross pay. The employee data will be input by the user by means of the constructor. There is a minimum of three Employee objects in the array. There is a method that will calculate the gross wages for each employee using the nested if else statements of an earlier program to deal with overtime issues. The data members of the Sales Person class are name, 4 digit id number, base salary, total sales and gross pay. The Sales person data will also be input by using constructor. The gross pay of the Sales Person will be based upon their weekly salary and commission. If total sales are less than or equal to $1000, the commission is 15% with 20% on sales between S1000 and S2000 and 25% on the sales over $2000. Both classes will have a toString method for output. There is a static menu method that will print the possible choices the user may make in manipulating the data and a switch that will process the choice. It will also calculate the total payroll for the week. The output will be in tabular form with a heading for name, id number (leading zeros) and the total weekly payroll. A repetition structure will allow for processing another tabular form with a heading for name, id number (leading zeros), gross pay gross pay ing another department. Menu Method: Patty's Payroll Progranm Please choose from the following 1. Input Employee Data 2. Input Sales Person Data 3. Compute Total Payroll 4. Print Report
