For the SalariedCompany class, write a test class called SalariedCompanyTest that tests the method getNextEmployee(..). Ensure you test it with three different inputs. (ii) Write a test class for SalariedEmployee class called SalariedEmployeeTest that tests the toString(..) method. Also test it with three inputs.
