Parking Lot Program help!
Hi guys,
In my Java Programming II class, we have to create a program that displays cars entering and exiting a parking lot. I created 50 JButtons (I know there is a more efficient way to write my code, but how?) and I'm trying to get the Buttons to display a .GIF image when pressed.
This is the error I'm getting:
There are 50 errors (button01, button 02 etc...) for each button. I just didn't feel like pasting all of them.F:\Parking.java:326: cannot find symbol
symbol : method add(javax.swing.ImageIcon)
location: class javax.swing.JButton
button01.add(splat);
This is my code:
/*Parking.java */ import javax.swing.*; import java.awt.*; import java.awt.event.*; public class Parking extends JFrame implements ActionListener { //NUMERICAL DECLARATIONS double hourlyRate; double tow; double dailyRate; int timeIN = 0; int timeOUT = 0; int counter = 0; int numCars = 0; ImageIcon splat = new ImageIcon("images/middle.gif"); private JMenuBar mainBar = new JMenuBar(); private JMenu menu1 = new JMenu("File");

Container con = getContentPane(); if(source == exit) { System.exit(0); } else if (source == profitReport) { profitFrame(); } } public static void main (String[] args) { Parking frame = new Parking(); } }
As I said before, I'm still a beginner, but I know there has to be an easier way to write something like this; perhaps an array and forloops? We've learned all about them; I'm just not sure how I would use them to change individual JButtons, as opposed to all 50 of them.
This is what we have to write:
Write a program that keeps track of cars entering a parking lot:
I also referenced the Profit Report class: here is that code.
- Time in/Time Out
- 50 Parking Spaces
- $2 per hour
- $12 per day option
- No Overnights
- Hours of Operation: 7AM to 11PM (24 hour clock maybe?)
- End of Day Profit Report
import javax.swing.*; public class ProfitFrame extends JFrame { final int width=350; final int height=350; final int width2=500; final int height2=500; public ProfitFrame() { super("GMoney Parking Profit Report"); setSize(width,height); setVisible(true); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }
ANY HELP WOULD BE MUCH APPRECIATED!!
