Write a class Employee. An employee has a private first name (string), private last name (string), private job title (string), private employment ID (string), private monthly income (double), private joining date (string), and private mailing address (string). Provide a default constructor, a parameterized constructor, and a clone constructor. Write separate setters and getters for each private instance variable. Your Employee class should also keep track of number of employees that have been added to your system.
Write another class BusinessConcern, which acts as your main class. Inside main method, create a one-dimensional array of objects of Employee type. At the start of your program, it should prompt for total number of employee records to be added to the system. After creating an array of desired number of employees, your program shall provide a console-based menu to user with following options:
1) New Employee Record (input: values for initialization of instance variables of new employee object/instance)
2) Change Job Title (required input: employment ID, new job title)
3) Change Monthly Income (required input: employment ID, new monthly income)
4) Change Mailing Address (required input: employment ID, new mailing address)
5) Employee Details (required input: employment ID)
6) List All Available Records
7) Exit Program
