PBO 7 (Scanner)

Sebuah Program tentang Tech Suppport System. Program dapat menerima inputan dan akan memberikan respon secara sederhana, dan ketika mendeteksi input "bye', program akan berhenti.

>Main Program

 /**  
 * This class implements a technical support system. It is  
 * the top-level class in this project. The support system  
 * communicates via text input/output in the text terminal.  
 * This class uses an object of class InputReader to read  
 * input from the user and an object of class Responder to  
 * generate responses.  
 * It contains a loop that repeatedly reads input and  
 * generates output until the user wants to leave.
