Hello. I got a class project to make a cell phone service. So far i got this much done:

import java.io.*;
import hsa.Console;
public class cell
{
static Console c = new Console (25, 65);
static String user = "Guest", pass = "Sample", entry = "", enter = "";

static char letter;
static String acall, caller, call1, call2;

}I seem to be getting an error here. This part is in the end of the code abouve: if (enter.equals (user) == true)

c.println ("Turn Off");

c.setTextColor (Color.white);
option1 = c.readLine ();
c.setTextColor (Color.black);
if (option1.equals ("Menu") == true || option1.equals ("menu") == true)
{
c.clear ();
c.println ("Dark Cell Services");
c.println ();
c.println ("This Section Is Currently Under Construction.");
c.println ("Please Check Back For Furth Updates.");
c.println ();
c.print ("Go Back? ");
c.setTextColor (Color.white);
back1 = c.readLine ();
c.setTextColor (Color.black);
if (back1.equals ("no") == true || back1.equals ("No") == true)
{
c.println ("Thank You For Using Our Service.");
break;
}
}
else
if (option1.equals ("Make A Call") == true || option1.equals ("make a call") == true || option1.equals ("Make a call") == true)
{
c.clear ();
c.println ("Dark Cell Services");
c.println ();
c.setTextColor (Color.white);
c.println ("THIS SECTION IS CURRENTLY OFF LIMITS.");
c.println ("WE HAVE BEEN EXPERIENCING A FEW BUGS.");
c.println ("AS SOON AS THEY ARE FIXED, THIS SECTION WILL BE BACK.");
c.println ();
c.println ("THANKS,");
c.println ("DARK CELL SERVICES STAFF");
}
}
while (back1.equals ("Yes") == true || back1.equals ("yes") == true);
}The error occurs when i go to make a call and it has something to do with the do/while loop i think cause when i go to make a call, i get some error and the while loop is highlighted black which means it's causing the problem. Can someone figure out what i'm doing wrong here? EDIT I also need some help on how i can load a .wav or a picture file here. Last edited by Dark Flare Knight; Apr 25th, 2005 at 8:50 PM. |

while (back1.equals ("Yes") == true || back1.equals ("yes") == true);if it is this while loop then it should be
while (back1.equals ("Yes") || back1.equals ("yes") );
or
while (back1.equalsIgnoreCase ("Yes"));you do not need the "== yes" part as the above evaluation will be true and go into the loop or false and not. |

try with initilising the back1 variable in the program first before you use it.

Voted. If you are still having problems by the time I get home, I will look into it some more... i don't have access to javac at the moment.

Ok, I googled a bit and here's what I found:
this is for adding sound: http://data.uta.edu/~telemm/JavaSound/ this is for adding pictures: http://www.sunncity.com/Tutorial_Jav...Two/swing.html http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Toolkit.html#getImage(java.lang.String) I hope it helps ... i'm amazed i couldn't find anything better .....
