Address + Student + GenderType

This revised version of the Student class now has an Address field. The address field is new; although similar to the CanadianAddress class, the Address class is simpler and more "generic" (having "State" instead of "Province" and "ZipCode" instead of "PostalCode").

Problem Statement

Extend the Student class to now include information about the student's home address. Create an Address class to represent a simple, generic address. In addition, the Student class must represent the Gender using an enumeration.

The solution must meet the following requirements (new requirements are in bold):

• The Address class must
  • Get and set the city, state, street, unit and zip code.
• The Student class must
  • Verify that an address object is supplied (is not null)
  • Represent the Gender as a GenderType of Male and Female
  • Should get and set the student's name, gender, GPA, program of studies, and whether or not the student is full-time.
  • Should override the toString() method to get the student's ID and name in this format:
    (ID) Name
  • Should no longer allow the student ID to be set (it's only set through the constructor)
  • Should reject empty text (and null values) for the student's name and program of studies.
  • Should trim the student's name and the program name
  • Should only accept ‘M' and ‘F' as valid genders
  • Should set the gender to upper-case
  • Should reject negative GPAs and GPAs over 9

Use the following class diagrams to guide your design.
