Part 1,Concept Understanding — Short Answer (1.5points)

1. Write the first line of a Calico class thatinherits from the Cat class.

2. explain (in your own words) the differences between a protectedclass member and a private class member in terms of its visibilityand inheritance?

3. When does dynamic binding happen?

1. Hospital.java (driver)
2. HospitalEmployee.java (super class)
3. Doctor.java (subclass of HospitalEmployee)
4. Nurse.java (subclass of HospitalEmployee)
