Java

Modification 10: Write a method called addEmployee, which doesnt return a value and has 1 parameter of type Employee. It adds a copy of the Employee parameter to the listOfEmployees instance variable.

Note:

You need to use the instanceof operator to cast the parameter into either HourlyEmployee or SalariedEmployee; very similar to how its done in the constructors except that youll be working with only one Employee object as opposed to an ArrayList.

The following is the method signature:

public void addEmployee(Employee employee)

{

// provide implementation

}
