Jbutton listener isn't triggered, why?

Question

I'm trying to get my basic GUI working and my navigation set up before attempting the coding for the functionality. Basically I have a login form that work and opens my menu page when the user correctly enters the login details. I have an AddProperty page I wish to open when the click on the Jbutton (this new page should open and the menu page closed). I have been using the Head First Java book to try and complete this task.

When I click on the Jbutton, nothing happens. It might be something to do with the structure of my code as I am a beginner and just trying to familiarize myself with the code. Thanks for looking!

Here's the menu Page (NavigationMenu.java):

    /** Creates a new instance of NavigationMenu */
    public void NavigationMenu() 
    {
        JFrame menu = new JFrame("menuframe");
        menu.setVisible(true);
        JPanel panel = new JPanel(new FlowLayout(FlowLayout.LEFT));
        menu.setSize(180,240);
        menu.add(panel);

        menu.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JButton AddProperty = new JButton("Add A Property");
        panel.add(AddProperty);

        //AddProperty gui = new AddProperty();
                   //gui.AddProperty();

        JButton CreateNewAccount = new JButton("Create New Account");
        panel.add(CreateNewAccount);
        JButton SearchProperty = new JButton("Search Property");
        panel.add(SearchProperty);
        JButton ViewPropertyDetails = new JButton("View Property");
        panel.add(ViewPropertyDetails);
        JButton Logout = new JButton("Logout");
        panel.add(Logout);

    }     
        public void actionPerformed(ActionEvent e)

        { 

        if (e.getActionCommand().equals("Add A Property")) 

                { 
                   AddProperty gui = new AddProperty();
                   gui.AddProperty();
                }
        //the user pressed "Add A Property"; do something
}
}

Here's the contents of AddProperty.java:

public class AddProperty

    public void AddProperty()
    {

        JFrame frame = new JFrame("AddPropertyFrame");
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        // having to set sizes of components is rare, and often a sign    
        // of problems with layouts.
        //frame.setSize(800,600);
        JPanel panel = new JPanel(new FlowLayout(FlowLayout.CENTER, 20,20));
        // make it big like the original
        panel.setBorder(new EmptyBorder(100,20,100,20));
        frame.add(panel);
        //panel.setLayout(new BoxLayout(panel, BoxLayout.X_AXIS));

        JLabel HouseNumber = new JLabel("A");
        panel.add(HouseNumber);
        JTextField HouseNumber1 = new JTextField(10);
        panel.add(HouseNumber1);

        JLabel HousePrice = new JLabel("B");
        panel.add(HousePrice);
        JTextField HousePrice1 = new JTextField(10);
        panel.add(HousePrice1);

        JLabel HouseType = new JLabel("C");
        panel.add(HouseType);
        JTextField HouseType1 = new JTextField(5);
        panel.add(HouseType1);

        JButton submit = new JButton("Submit");
        panel.add(submit);
        submit.addActionListener(new Action());

        // tell the GUI to assume its natural (minimum) size.
        frame.pack();
    }

    static class Action implements ActionListener{

        @Override
        public void actionPerformed (ActionEvent e)
        {
            // this should probably be a modal JDialog or JOptionPane.
            JFrame frame2 = new JFrame("Submitted");
            frame2.setVisible(true);
            frame2.setSize(200,200);
            JLabel label = new JLabel("You Have Submitted a New Property");
            JPanel panel = new JPanel();
            frame2.add(panel);
            panel.add(label);
        }
    }
}

Answer 1

It should be

public class NavigationMenu implements ActionListener{

and you should add the listener to the button:

AddProperty.addActionListener(this);

Answer 2

firstly, your constuctor for NavigationMenu menu is wrongly defined.

it should not be returning void. constructors do not return values

public NavigationMenu()
{
etc...
}

same with AddProperty class

looking at the rest now. :)

to fix the rest you need to assign an action listener to the button

AddProperty.addActionListener(this);

and the NavigationMenu must implement the ActionListener inteface. i.e.

public class NavigationMenu 
implements ActionListener
