Question

Write a program that implements a rudimentary name-finder. It should start out by filling up a name ArrayList with Name objects. Then it should ask the user if he/she wants to find a particular name. Then it should search for the name in the name ArrayList and return the names information if the name is found. Here is a suggested UML class diagram:

Implement Name filltheblackbook method by adding anonymous objects representing these four names:

First Name                       Last Name               Address

Sara           Smith       123 N 53^rd

Lolita         Edwards     672 E 22^nd

Kyle           Johnson     456 W 29^th

Elizabeth      Waitsmith   521 S 3^rd

Implement Name’s getName method so that if the name is not found, the method returns the string:

"Sorry – that name is not in the black book."

Implement Name’s toString method simply by returning this string value:

First Name + " " + Last Name + " " + Address
