The main driving class only creates twoobjects, one is an Employee(Vito), the second one is an Administrator(Jason).When you run your program, you may see the result like this:> run HospitalVito 123 Jason is a HR department Administrator.Please use "extends, super, and protected" in the appropriate places to show inheritance. Youneed three files to work on the project, Hospital Employee.java(no need to change from theexample), Administrator.java(create this new file), and Hospital.java(add some statements to it).Note: please use inheritance, meaning Administrator class inherits HospitalEmployee. You willnot get credit if you do not use inheritance in the spots where inheritance should be used in theclass Administrator. Doctor and Nurse are good template for Administrator.
