EmailDirectory

Background:

In this lab, you will create a class EMDirectory that stores email addresses as strings that are stored and accessed by name. The constructor reads the information from a file and sets up your directory. Your directory will then be able to add a name and email address, lookup the email address that goes with a name, look up all email addresses that have names with the same last name, and return a set of strings that includes all name/email pairs.

Assignment:

1. You will be provided with a program shell consisting of an EMDirTest class containing a main method, the Name class that encapsulates a person’s name, and the EMDirectory class. All of the code development should appear in the EMDirectory class. Here are some of the specifications of the EMDirectory class.

   1. The addEntry(Name name, String emailAddr) method takes a name of type Name and an email address, as a String, and stores them in the Map.

   2. The lookup(Name name) takes a Name object as a key and returns the corresponding email address as a String.

   3. The lookupLastName(String lastName) takes a last name, as a string, and returns a set of all email addresses stored with any name that has that last name.

   4. The listAll() displays the name and the email address for each item in the directory.

   5. A method to read the data file is provided.

Instructions:

1. The data file to be used in this lab is emdir.txt.

2. Modify and write code as necessary to satisfy the above specifications.

3. You will be provided with a sequence of operations to perform to test the class.

4. Submit the source for the EMDirectory class along with the run output.
