2. A driver class that drives the use of the classes and prints out appropriate information about the entities

4. Use of “super” keyword
5. Use of “this” keyword
6. Use of “tostring” method

10. Use of appropriate formatting to print output
11. Use the java date class for processing dates (birth date, joining/anniversary date etc.)
12. Use of interfaces (if any)
13. Display polymorphic handling of classes using array (demo as well as examples in book)
