I'm new to java and for some reason I don't know any other way to transfer the data from another frame after pressing submit. For example, it will show the output frame the label and textfield that the user wrote in the first frame like this "Name: "user's name". If you do know please post the code I should put, thank you!

It's not clear what problem you are having displaying a value from one field in another frame. But here's an example of doing that (with fields reduced to just one for demonstration):
public class EventDriven extends JFrame {
private final JTextField nameField = new JTextField(15);
private final JButton submit = new JButton("Submit");
private final JButton clear = new JButton("Clear All");
public EventDriven() {
setTitle("Input");
setLayout(new FlowLayout(FlowLayout.CENTER));
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
add(new JLabel("Name: "));
add(nameField);
submit.addActionListener(this::showOutput);
add(submit);
clear.addActionListener(this::clearInput);
add(clear);
pack();
}
private void showOutput(ActionEvent ev) {
submit.setEnabled(false);
JDialog output = new JDialog(EventDriven.this, "Output", true);
output.add(new Label("Name: " + nameField.getText()), BorderLayout.CENTER);
JButton okButton = new JButton("OK");
output.add(okButton, BorderLayout.SOUTH);
okButton.addActionListener(bv -> output.setVisible(false));
output.pack();
output.setVisible(true);
}
private void clearInput(ActionEvent ev) {
nameField.setText(null);
submit.setEnabled(true);
}
public static void main(String[] args) {
EventDriven window = new EventDriven();
window.setVisible(true);
}
}
You will also see that I've simplified your action listeners to demonstrate an easier way to respond to user driven event.s
Im currently creating a GUI from scratch and I am including multiple classes on one page. Unfortunately, something is preventing me from seeing a class and I think it has to do with opening and closing brackets. Can anyone possibly help with where I went wrong so I dont do this in the future? My program is throwing an exception at RentalPanel class. It does not see it for some reason.

The trouble is, the RentalPanel class is a non-static inner class inside CustomerPanel. So you cannot directly access it from MavGUI2 class. Making RentalPanel and CustomerPanel classes static inner classes, will solve the compilation error.
In fact, it would be advisable to move them to their separate files.
Im fairly new to Java and im just looking for a little help Im trying to create a program which allows the user to enter as a gui the name and> >location of a department store. It allows this but the program does not wait for the >details to be entered it just initializes the Gui class and simply continues on with the >processing Which is to add the details entered into the Gui into an array list. But the >details have not yet been entered yet so it is creating a null value because it has jumped >ahead.
So how can I make it stop and wait till the values have been entered and then submitted?
Here is the Gui component of the code:

public class guiDepartment extends JFrame

You shouldn't have a JFrame launching other JFrames, especially if you want the child windows to behave as a modal dialogs -- a dialog that halts the code in the launching window until it has been fully dealt with. When this is the case, make the dialog windows dialogs by using modal JDialogs in place of JFrames for the dialog windows.
For example:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class MainWelcomeGui2 {
public static void main(String[] args) {
final JFrame frame = new JFrame("Main GUI");
JButton addDeptButtonLaunchJFrame = new JButton(
"Add a New Department, Launch JFrame");
JButton addDeptButtonLaunchJDialog = new JButton(
"Add a New Department, Launch JDialog");
addDeptButtonLaunchJDialog.addActionListener(new LaunchJDialogListener(
frame));
addDeptButtonLaunchJFrame.addActionListener(new LaunchJFrameListener());
JPanel panel = new JPanel();
panel.add(addDeptButtonLaunchJDialog);
panel.add(addDeptButtonLaunchJFrame);
frame.add(panel);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
}

}
#Override
public void actionPerformed(ActionEvent e) {
System.out.println("called before setting dialog visible");
dialog.setVisible(true);
System.out
.println("called after setting dialog visible. Note that this line doesn't show until the dialog disappears");
}
}
class LaunchJFrameListener implements ActionListener {
JFrame frame;
public LaunchJFrameListener() {

frame.dispose();
}

My program is about a supermarket. I want to position the JButton 'b1' just below JLabel 'l1' and also below JTextField 'jt1'. I want the JButton 'b1' to also be in the centre but below 'l1' and 'jt1'. Below is the delivery() method of my program:
public static void delivery()
{
final JFrame f1 = new JFrame("Name");
f1.setVisible(true);
f1.setSize(600,200);
f1.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f1.setLocation(700,450);
JPanel p1 = new JPanel();
final JLabel l1 = new JLabel("Enter your name: ");
final JTextField jt1 = new JTextField(20);
JButton b1 = new JButton("Ok");
b1.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
input1 = jt1.getText();
f1.setVisible(false);
}
});
p1.add(b1);
p1.add(l1);
p1.add(jt1);
f1.add(p1);
final JFrame f2 = new JFrame("Address");
f2.setVisible(true);
f2.setSize(600,200);
f2.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
f2.setLocation(700,450);
JPanel p2 = new JPanel();
final JLabel l2 = new JLabel("Enter your address: ");
final JTextField jt2 = new JTextField(20);
JButton b2 = new JButton("Ok");
b2.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
input2 = jt2.getText();
f2.setVisible(false);
}
});
p2.add(b2);
p2.add(l2);
p2.add(jt2);
f2.add(p2);
}
}
You can use multiple JPanels to get close to what you want:
import java.io.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class MyGui {
public static void delivery()
{
JFrame f1 = new JFrame("Name");

Container cpane = f1.getContentPane();
JPanel p1 = new JPanel();
p1.setLayout(new BoxLayout(p1, BoxLayout.LINE_AXIS)); //Horizontal
JLabel l1 = new JLabel("Enter your name: ");
JTextField jt1 = new JTextField(20);
jt1.setMaximumSize( jt1.getPreferredSize() );
p1.add(l1);
p1.add(jt1);
JPanel p2 = new JPanel();
p2.setLayout(new BoxLayout(p2, BoxLayout.PAGE_AXIS)); //Vertical
p2.add(p1);
JButton b1 = new JButton("Ok");
p2.add(b1);
cpane.add(p2);
f1.setVisible(true);
}
}
public class SwingProg {
private static void createAndShowGUI() {
MyGui.delivery();
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable() {

}
}
Use the GridBagLayout Class. It's for custom designing using Constraints.

Buttons need Event Handlers to work. You have not added any Event Handlers to the Save and Delete buttons. You need to call the addActionListener on those buttons too.
I recommend anonymous inner classes:
mybutton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
//do whatever should happen when the button is clicked...
}
});
You need to addActionListener to the buttons btSave and btDelete.
You could create a anonymous class like this and perform your work there.
btSave.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
//Do you work for the button here
}
}
btDelete.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
//Do you work for the button here
}
}
Edit:
I have an example to which you can refer to and accordingly make changes by understanding it. I got it from a professor at our institute.
