Question

********************Java Assigment*******************************

1. The following interface and classes have to do with the storage of information that may appear on a mailing label. Design and implement each of the described classes below.

public interface AddrLabelInterface {

String getAttnName();

String getTitle(); // Mr., Mrs., etc.

String getName(); String getNameSuffix(); // e.g., Jr., III

String getProfessionalSuffix(); // O.D. (doctor of optometry)

String getStreet();

String getSuiteNum();

String getCity();

String getState();

String getZipCode(); }

Step 1

Create an abstract AddrLabel class that implements the AddrLabelInterface. Implement the following methods to return an empty string: getAttnName(), getTitle(), getNameSuffix(), getProfessionalSuffix(), and getSuiteNum(). The rest of the methods should be left unimplemented (i.e., as abstract methods).

Step 2

Create a class named FriendAddrLabel declared as a (concrete) subclass of the abstract AddrLabel class. The FriendAddrLabel class should be designed to store only the Name, Street, City, State and ZipCode fields.

e.g., Jeff Taylor

143 Main St.

Towson, MD 21250

Step 3

Create a class named CompanyAddrLabel declared as a (concrete) subclass of the abstract AddrLabel class. The CompanyAddrLabel class should be designed to store only the AttnName, Title, CompanyName, Street, City, State and ZipCode fields.

e.g., ATTN: Rebecca Rollins

A1 Technology

92 Autumn Drive

Keene, NH 03431

Step 4

Create a class named ProfessionalAddrLabel declared as a (concrete) subclass of the abstract AddrLabel class. The ProfessionalAddrLabel class should be designed to store only the Name, ProfessionalSuffix, Street, Suite, City, State and ZipCode fields.

e.g., Sarah K. Phillips, O.D.

100 Oak Street, Suite 904

Omaha, NE 68007

2. Design and implement a class named LabelGenerator that is constructed to contain an object of type AddrLabelInterface. The class should contain the following static method (in addition to any other supporting methods),

public static String[] getLabelLines(AddrLabelInterface addr)

that returns in the array of strings the address lines as they should be printed for the given address label type.

3. Create a simple main program that creates a number of address object types, and stores in an array of type AddrLabelInteface. Using a simple for loop, display each label one by one in the array
