Thread: CAR PARK SIMULATOR

Hi, im currently struggling with my java coding and as you can see from my work it isn't very good haha. i'm currently trying to add images to my jlabels once someone has entered there details for a Car, Lorry or Coach, i was wondering if anyone could help me with it.

p.s if anyone want's to do the whole project i will pay you haha

Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

Post the code you need help with between code tags as described in the link I provided above. If you're getting errors, post those. If you're just lost, don't know what to do, then describe why you're confused. Post some code and ask specific questions, then we can help.

There is an area here to post advertisements for paid work, but most here will not participate in academic dishonesty.

I did recently post an example of a single-thread pizza parlor simulation that you might find helpful, but I'm not sure since I haven't reviewed your assignment.

Good luck.

sorry, its not that i'm getting errors it because i'm finding it impossible as a beginner at Java to add images to my Jlabels when someone enters details, i may of posted it in the wrong section, can i forward it?

COM1077-N ICA 2 (2013-14)(1).pdf

Here's my brief if you find this helpful?

sorry i won't post anything else, i thought it would be better to attach my project.
These are my problems:

1. When some presses OK on the JoptionPane after entering the details for the Car/Lorry/Coach, an image is suppose to appear onto the JLabels for the CarPark which i don't know how to do.

2. as you can see on my document i need add functions to the rest of my buttons which are "ClearAll, Save, Load, CurrentTotal and OverallTotal

if you or someone could help me with this it would be much appreciated, if someone wants paying to do this. give me a price and i will happily pay.

Thank you for your help Norm

i've attached my code in the thread.

i've got a class for each vehicle which has a method (the code shown is in the car class)

public ImageIcon GetImage(){ ImageIcon car = new ImageIcon ("images/car.jpg"); return car;

then in my GUI class i have this for when someone wants to enter the details for the car:

if (me.getSource() == buttons[0]) { //"Add Car Button Click"   JPanel addCarPanel = new JPanel(); addCarPanel.setLayout(new GridLayout(4, 2));   addCarPanel.add(new JLabel("Reg no.")); JTextField regNumField = new JTextField(8); addCarPanel.add(regNumField);   addCarPanel.add(new JLabel("Length. ")); JTextField lengthField = new JTextField(3); addCarPanel.add(lengthField);   JCheckBox disabledBadge = new JCheckBox(""); addCarPanel.add(new JLabel("Disabled Badge ")); addCarPanel.add(disabledBadge);   addCarPanel.add(new JLabel("Number Of Hours ")); JTextField hours = new JTextField(3); addCarPanel.add(hours);   int optionCar = JOptionPane.showConfirmDialog(this, addCarPanel, "Add Car", JOptionPane.OK_CANCEL_OPTION);   if (optionCar == JOptionPane.OK_OPTION) { System.out.println("Reg num entered: " + regNumField.getText()); System.out.println("Length of Car: " + lengthField.getText()); System.out.println("Disabled Badge: " + disabledBadge.isSelected()); System.out.println("Number of hours: " + hours.getText()); //CarLabels[] = new ImageIcon("images/car.jpg"); //Carlabels.setIcon(car);   double intLength = Double.parseDouble(lengthField.getText()); int h = Integer.parseInt(hours.getText());     Car CarNew = new Car(regNumField.getText(), intLength, disabledBadge.isSelected(), h); }

this is where i am stuck ??
