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)
