Final Project - Code: V.1

This was the first draft of the programming. The goals was to have some output given a certain input. This actually took longer than I expected to code, but I'm pretty proud of this simple version.

import java.util.Scanner;

/**

* This class holds the first prototype for the chatterbot

* Goals:

*Have computer respond to certain questions based on user input question

*Print this response to the console

* Problems with this version:

*Using the next() with the Scanner only grabbed the next word and not the entire line

*So none of the arrays were being read

*Solution: nextLine() reads the entire line (thanks Stack Overflow! http://stackoverflow.com/questions/4058912/scanner-doesnt-read-whole-sentence)
