Question

Assignment

Examine the Main and Address classes. You are going to add two classes derived from Address: BusinessAddress and PersonAddress.

Create BusinessAddress class

1. Select package home and create a new Java class called BusinessAddress
2. Make the class extend the Address class
3. Add two private String fields businessName and address2
4. Generate constructor and all getters and setters
5. Add a printLabel() method

The printLabel method should print (using System.out.println())

First line – the businessName field

Second line – the address2 field if it is not null or empty

Third line – the StreetAddress field if it is not null or empty

Fourth line – city field followed by a comma and space, the state field followed by two spaces, and the zip field

Create PersonAddress class

1. Select package home and create a new Java class called PersonAddress
2. Make the class extend the Address class
3. Add a private String field personName
4. Generate constructor and all getters and setters
5. Add a printLabel() method

The printLabel method should print (using System.out.println())

First line – the personName field

Second line – the StreetAddress field

Third line – city field followed by a comma and space, the state field followed by two spaces, and the zip field

Modify Main class

Add the following three BusinessAddress objects to the list.

BusinessName	Address2	StreetAddress	City	State	Zip
Columbus State	Eibling 302B	550 East Spring St.	Columbus	OH	43215
AEP	P.O. Box 2075	null	Columbus	OH	43201
Bill’s Coffee	null	2079 N. Main St.	Columbus	OH	43227

Add the following three PersonAddress objects to the list.

PersonName	StreetAddress	City	State	Zip
Saul Goodman	1200 N. Fourth St.	Worthington	OH	43217
Mike Ehrmentraut	207 Main St.	Reynoldsburg	OH	43211
Gustavo Fring	2091 Elm St.	Pickerington	OH	43191

Example Output
