this is my code... Thanks for helping...

This is program , i uploaded it in here, because there are images in here that are needed

http://www.mediafire.com/?m3fe3rk2kq3j9w4

Could you post the code here or at least the important parts concerning the problem and also the error messages

most commonly used way:

keep a number of Chair elements, or an int counting the number of chairs, depending on the structure of your code,
as an instance variable and use either the constructor or a setter.

This is my code...
my problem is that my barbersBack image is static, because its only jpg format...
i would like that i will input some number of barber chairs and also i will input how many barbers that i want, so that when customers come in, for example they will occupy the barbers sit, please help me...

Edited 3 Years Ago by Dani: Formatting fixed

no i mean that my barbersBack jpg format image is not changable ... because its jpg, i want that whenever i run my program, it shouldnt have barbers chair at all, so i will input how many chairs i like and also how many barbers and appear it in my gui, how to do these??... pls help

not changable, then you should use "final" instead of static. static can still be changed.

keep a list of chairs, and instantiate that list in your constructor.
add an addChairmethod in which you add a chair each time it's called.

at the end of the adding, you'll need to repaint a part of your gui, or reset the value of a textArea or JComboBox (or what else you use, didn't read the entire code above)

hmf... i dont get it.. sir can you give me sample code to these... and i will understand it...

since I'm not totally clear on what exactly you're trying to do, not really. but:
when you instantiate your barber (if you have a Chair class)

private ArrayList<Chair> myChairs;
public Barber(){
// your code
myChairs = new ArrayList<Chair>();
}
....
public void addChair(){
  addChair(new Chair());
}
public void addChair(Chair newChair){
  myChairs.add(newChair);
}

ahm... about the image of the chair that i want to put , where will i put it, in that code sir?
