Create a sub class named Administrator, which is also a kind of employee in a hospital. Please add the following structures to Administrator class.

	Identifiers for field or methods	Data type for field or parameters for methods	Additional requirement
Field added	department	String
Methods to be handled	Administrator	Parameter:empName, empNumber,dept	The method Administrator is a constructor.
	setDepartment
	getDepartment
	toString		Returns a description of this administrator as a string
	administrate		Prints a message appropriate for this administrator

Then add statements in the example main driver file(Hospital.java) and exercise the main class. You may remove the statements for the objects of Doctor and Nurse in the main driver class because they were implemented in the examples. The main driving class only creates two objects, 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 Hospital

Vito 123

Jason 404 HR department

Vito works for the hospital.

Jason is a HR department Administrator.

Please use extends, super, and protected in the appropriate places to show inheritance. You need three files to work on the project, HospitalEmployee.java(no need to change from the example), Administrator.java(create this new file), and Hospital.java(add some statements to it).
