Version II

   public void readCharacterData() throws IOException   {     int c;     int count = 0;     BufferedReader br = new BufferedReader(System.in);     while ( (c = br.read()) ! = -1)     {       Count+ +;       System.out.println(c + " " + (char)c);     }     System.out.println("Number of Characters: " + count);   }
