Travel expenses GUI "Calculate reimbursement" button not responding

I can get the input box to appear, and can enter all of my data. The reset button works, but I cannot figure out why the calculate button refuses to show the output reimbursement.

Java: Action Handler

I am working on a problem for school and I am having an issue with the CalculateButtonHandler. I am also using an ExitButtonHandler but that is not giving me any issues. I have tried re-reading my textbook and have searched the web. After racking my brain over this issue I can't figure out why this won't work. This is my first GUI attempt and I am sure I will have to mess with the program to get it the way I want. I only want to know how to fix this CalculateButtonHandler issues as I can work on the rest if need be. Below is the code for the project.
Issues:
Lines 38, 76 and 77: CalculateButtonHandler cannot be resolved to a type.
What does this mean and how can I go about fixing it?

CalculateButtonHandler cannot be resolved to a type
Is telling you it can't find a class by that name:
private class CalculateButtonHanlder implements ActionListener
You have a typo "Hanlder"
private class CalculateButtonHandler implements ActionListener

You spelled `CalculateButtonHandler' as 'CalculateButtonHanlder' when you declared the class on line 120. Fix that and it will work.

Your program throw multiple NullPointerExceptions. You declare many objects as class fields and then never initialize them. You need to add at least:
inputPanel = new JPanel(); in constructor,
panel = new JPanel(); in buildPanel();
and in case of all yours JTextFields, change from:
JTextField field = new JTextField();
to:
field = new JTextField();
But it is only beginning because you GUI doesn't display most of components. You need to choose LayoutManager, and work with it. You add all your panels to center of your frames BorderLayout and I think they overlap . So for example, to see your JTextFields, JLabel and JButton, you can change add(component); in constructor for:
add(BorderLayout.NORTH, messageBar);
add(BorderLayout.CENTER, inputPanel);
add(BorderLayout.SOUTH,calculateBar);
also add:
panel.setLayout(new BoxLayout(panel,BoxLayout.PAGE_AXIS));
in buildPanel() method, and it will look better.
Whats more, you need to move code for JOptionPane to the end of calcCharges() method, this way it will have access to processed date and it will display proper output. At beginning of a app, it displays only zeros.

Java - GUI: Passing values from frame to another

I am making a panel project that calls three panels. Panel one holds all information and the other two panels are panels that open up when I press a button. How it works is I call the first panel, press a button, second panel opens. Then in the second panel I plug in a password. If it is correct, a third panel will open. I need to call values from the first panel into the third panel. I know how to use constructors, accessors and mutators, but the values I need are generated in an event when I press a button. I am trying to figure out how to call those values from the event into the third panel. Essentially, the values are counters, sub-total, tax, and total for all transactions of the duration of the program. Here is my code.
Main Class:
import javax.swing.*;
public class AppleRegister {
public static void main(String[] args)
{
double subTotalp2 = 0, taxP2 = 0, realTotalp2 = 0;
JFrame frame = new JFrame("Apple Crazy Cola Cash (Apple IIC) Register");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
AppleRegisterPanel panel = new AppleRegisterPanel
(subTotalp2, taxP2, realTotalp2);
frame.getContentPane().add(panel);
frame.pack();
frame.setVisible(true);

realTotalp2 += subTotalp2 * taxP2;
}
}
}
If you scroll down to TempListner2 and see the variables subTotalp2, taxP2, realTotalp2; those are the variables I need to carry over. You'll see that I made the constructor have those variables in it so I can call the methods over in the third panel, but no dice. Comes up 0.0 when I open the third panel. Not sure if it is because it is in a void event or not. I'll post part of the third panel here where I am trying to call the constructor from the first panel and inset the values into the third.
Third Panel:
public AppleRegisterPanel2()
{
AppleRegisterPanel p = new AppleRegisterPanel(subTotalp2, taxP2,
realTotalp2);
this.subTotalp2 = subTotalp2;
this.taxP2 = taxP2;
this.realTotalp2 = realTotalp2;
subTotalp2 = p.getSubTotal();
taxP2 = p.getTax();
realTotalp2 = p.getTotal();
You'll see here that I am trying a weird ass way to call the values.

One problem is that you're opening another JFrame from a JFrame, when you should instead be displaying a modal JDialog. The reason for this is that you cannot advance your program until the user enters the appropriate information, and so the 2nd window should be modal which will prevent interaction with the underlying window until the dialog window has been completely dealt with. If you do this, and place your JPanel into a modal JDialog, then you can easily query the results from the 2nd JPanel because you will know in your code exactly when it's been dealt with -- your main GUI code resumes exactly from where you set the modal dialog visible.
For example:
import java.awt.Window;
import java.awt.Dialog.ModalityType;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
public class WindowCommunication {
private static void createAndShowUI() {
JFrame frame = new JFrame("WindowCommunication");
frame.getContentPane().add(new MyFramePanel());
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
// let's be sure to start Swing on the Swing event thread
public static void main(String[] args) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
createAndShowUI();
}
});
}
}
class MyFramePanel extends JPanel {
private JTextField field = new JTextField(10);
private JButton openDialogeBtn = new JButton("Open Dialog");
// here my main gui has a reference to the JDialog and to the
// MyDialogPanel which is displayed in the JDialog
private MyDialogPanel dialogPanel = new MyDialogPanel();
private JDialog dialog;
public MyFramePanel() {
openDialogeBtn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
openTableAction();
}
});
field.setEditable(false);
field.setFocusable(false);
add(field);
add(openDialogeBtn);
}
private void openTableAction() {
// lazy creation of the JDialog
if (dialog == null) {
Window win = SwingUtilities.getWindowAncestor(this);
if (win != null) {
dialog = new JDialog(win, "My Dialog",
ModalityType.APPLICATION_MODAL);
dialog.getContentPane().add(dialogPanel);
dialog.pack();
dialog.setLocationRelativeTo(null);
}
}
dialog.setVisible(true); // here the modal dialog takes over
// this line starts *after* the modal dialog has been disposed
// **** here's the key where I get the String from JTextField in the GUI held
// by the JDialog and put it into this GUI's JTextField.
field.setText(dialogPanel.getFieldText());
}
}
class MyDialogPanel extends JPanel {
private JTextField field = new JTextField(10);
private JButton okButton = new JButton("OK");
public MyDialogPanel() {
okButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
okButtonAction();
}
});
add(field);
add(okButton);
}
// to allow outside classes to get the text held by the JTextField
public String getFieldText() {
return field.getText();
}
// This button's action is simply to dispose of the JDialog.
private void okButtonAction() {
// win is here the JDialog that holds this JPanel, but it could be a JFrame or
// any other top-level container that is holding this JPanel
Window win = SwingUtilities.getWindowAncestor(this);
if (win != null) {
win.dispose();
}
}
}

Debugging code I have with 2 classes and a JFrame that holds 4 JPanels

I am looking for help to debug this program that I have written there are, no errors but the goal is to create a frame with three panels inside of it each of which has a titled border. I am having difficulty because my prompt requires of me to make 2 constructors and 2 classes so when I call the DailySales class in main I feel it doesn't include the other class.
So basically how can I make the panels show up while still keeping two classes and two constructors and how would I add titled borders to each of the JPanels, sorry but I'm having difficulty with the Oracle tutorial.
