   }  
   public void start(){  
     boolean finished=false;  
     printWelcome();  
     while(!finished){

b) InputReader

  * The text typed by a user is then chopped into words, and a set of words   
  * is provided.

  * @version  2008.03.30  
  */

    * Create a new InputReader that reads text from the text terminal.  
    */

     reader = new Scanner(System.in);  
   }  
   /**  
    * Read a line of text from standard input (the text terminal),  
    * and return it as a set of words.  
    *  
    * @return A set of Strings, where each String is one of the   
    *     words typed by the user  
    */  
   public HashSet<String> getInput()   
   {  
     System.out.print("> ");        // print prompt  
     String inputLine = reader.nextLine().trim().toLowerCase();  
     String[] wordArray = inputLine.split(" "); // split at spaces  
     // add words from array into hashset   
     HashSet<String> words = new HashSet<String>();  
     for(String word : wordArray) {  
       words.add(word);  
     }  
     return words;  
   }  
 }  

c)Responder

 public class Responder  
 {  
   /**  
     * Create a responder.  
    */  
   public Responder()  
   {  
   }  
   /**  
   * Generate a response.  
   * @return A string that should be displayed as the  
   * response  
   */  
   public String generateResponse()  
   {  
     return "That sounds interesting. Tell me more...";  
   }  
 }
