Rental Log

The goal of this assignment is to create classes that have relationship(s) with other objects. In this assignment we will create classes that will help make a rental office track their tenants (Rental Log).

For this problem, a person will be specified by first name, middle initial, and last name, and an apartment is specified by a street, a street number, an apartment number, and a tenant.

1. Define a Java class Person (Person.java) with
   • Data fields first and last names strings, the middle initial a character.
   • A three-parameter constructor that creates a Person object.
   • Methods: getFirstName(), getMiddleIntial(), and getLastName() that return the corresponding data values.
   
   
2. Define a class Apartment (Apartment.java) with
   • Data fields: immutable street, street number, and apartment number, and a mutable Person value representing the tenant (owner or renter) of the apartment.
     • mutable and immutable correpond to how this data is accessible
     • The street is a string, the street number and apartment number are integers.
   • An apartment object is created by a constructor call with four arguments: street, street number, apartment number, and tenant.
   • The Apartment class has:
     • Query methods: getStreet(), getStreetNmber(), getAptNumber(), and getTenant() and
     • Command method: changeTenant() that changes the apartment's owner.

Note: make sure that method name exactly correspond.

Here are some DrJava interactions with the classes

> Person a = new Person("Alice", 'Q', "Public");
> a.getLastName()
"Public"
> Person b = new Person("Bob", 'B', "Little");
> Apartment s = new Apartment("Spruce", 333, 2, a);
> s.tenant().getfirstName()
"Alice"
> s.changeTenant(b);
> s.tenant().getFirstName()
"Bob"
