Object Oriented Programming Implementation 1. How are properties different from methods? 2. When you retrieve an integer from a collection and modify the integer, what happens to the corresponding integer stored in the collection? How is this different from retrieving and modifying an object? 3. What happens to an object created inside a procedure when the procedure finishes? 4. When a property procedure or method in a base class is not appropriate for a derived class, what can you do? 5. Suppose class B is derived from class A. Class As UpdateData method has been over- ridden in class B. How can the UpdateData method in class B call the UpdateData method in class A? 6. Why are member variables usually declared Private in classes? 7. At the end of the following example, how many Student objects exist? Dim st1 As New Student Dim st2 As Student st2 = st1 8. At the end of the following example, how many Student objects exist? Dim st1 As New Student Dim st2 As Student st2 = st1 st1 = Nothing 9. Suppose that an application at an animal hospital uses two classes: Mammaland Dog. Which do you think is the base class and which is the derived class? Why? 10. Why does it make sense that you cannot use the Overridable keyword in a private base class member declaration?
