Thread: File handling in a GUI!

Hi Everyone,

I created a GUI using Java with Buttons, Pictures and labels.
When one of the buttons is pressed it increases the price, which can be seen by the labels increasing the necessary amount.

What I would like to be able to do in my GUI is allow the user to record details of the sale and be able to display the sales of past customers to date, by this I mean when I click one of the buttons it will record the amount of that item into a file and when I press the another button, not the same button as the items, it will show the user the existing orders that have been taken in the past.

Here is my Code:

 
//Importing needed classes
import java.awt.*;

import java.awt.event.*;
 
//The Main Class
public class CoffeeShop extends JFrame
{
	//Initialising the Buttons and Labels

	//Initialising the Screen Width and Length
	private static final int FRAME_WIDTH = 780;
	private static final int FRAME_HEIGHT = 400;
 
	//Initialising the Initial cost and Interest Rates of the items on sale
