So this question has been asked a lot, but I've searched through several of them and it seems that everyone is forgetting to add the panel to the frame. I have added the panel to my frame, but I still am not seeing my JPanel.

public class AddSomethingFrame extends JFrame{

private JFrame application;

JPanel viewPanel = new JPanel();



    public AddSomethingFrame(JFrame application) {

        super("Add");

        this.application = application;



        setDefaultCloseOperation(EXIT_ON_CLOSE);

        setPreferredSize(new Dimension(300, 200));

        placeComponents(viewPanel);

        viewPanel.setBorder(new EmptyBorder(13, 25, 13, 25));

        setLayout(new FlowLayout());

        setLocationRelativeTo(null);

        setResizable(true);

        pack();

        setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE);

        this.addWindowListener(new WindowAdapter() {

            public void windowClosing(WindowEvent e) {

                application.setVisible(true);

                setVisible(false);

                dispose();

            }

        });

        setVisible(true);

    }



    private void placeComponents (JPanel panel) {



        panel.setLayout(null);

        JLabel nameLabel = new JLabel("Name");

        nameLabel.setBounds(10, 10, 80, 25);

        panel.add(nameLabel);



        JTextField nameText = new JTextField(20);

        nameText.setBounds(100, 10, 160, 25);

        panel.add(nameText);



        JLabel brandLabel = new JLabel("Brand");

        brandLabel.setBounds(10, 40, 80, 25);

        panel.add(brandLabel);



        JTextField brandText = new JTextField(20);

        brandText.setBounds(100, 40, 160, 25);

        panel.add(brandText);



        JLabel costLabel = new JLabel("Cost");

        costLabel.setBounds(10, 10, 80, 25);

        panel.add(costLabel);



        JTextField costText = new JTextField(20);

        costText.setBounds(100, 10, 160, 25);

        panel.add(costText);





        JButton storeGearButton = new JButton("Store");

        storeGearButton.setBounds(10, 80, 80, 25);

        panel.add(storeGearButton);



        this.add(viewPanel, BorderLayout.NORTH);

    }



}

I've tried moving around the setVisible for the JFrame and the JPanel. I've tried changing the sizes of each and I tried changing the BorderLayout of the panel, but nothing is working. Please help.

I suggest you to avoid a "placeComponents(viewPanel)" construction and directly add the "JPanle panel" elements to your JFrame that will make your code easier. Somthing like that:

public class AddSomethingFrame extends JFrame{

static JFrame application;

//JPanel viewPanel = new JPanel();



public AddSomethingFrame(JFrame application) {

super("Add");

//    this.application = application;



setBounds(300, 200, 1000, 200);

setDefaultCloseOperation(EXIT_ON_CLOSE);

//    placeComponents(viewPanel);

//    viewPanel.setBorder(new EmptyBorder(10, 25, 2, 25));

//    setLayout(new FlowLayout());

//    setLocationRelativeTo(null);

//    setResizable(true);

//    pack();

//    setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE);

//    this.addWindowListener(new WindowAdapter() {

//        public void windowClosing(WindowEvent e) {

//            application.setVisible(true);

//            setVisible(false);

//            dispose();

//        }

//    });

//    setVisible(true);

//}

//

//    private void placeComponents (JPanel panel) {

JPanel panel = new JPanel();

//        panel.setLayout(null);

    JLabel nameLabel = new JLabel("Name");

    nameLabel.setBounds(10, 10, 80, 25);

    panel.add(nameLabel);



    JTextField nameText = new JTextField(20);

    nameText.setBounds(100, 10, 160, 25);

    panel.add(nameText);



    JLabel brandLabel = new JLabel("Brand");

    brandLabel.setBounds(10, 40, 80, 25);

    panel.add(brandLabel);



    JTextField brandText = new JTextField(20);

    brandText.setBounds(100, 40, 160, 25);

    panel.add(brandText);



    JLabel costLabel = new JLabel("Cost");

    costLabel.setBounds(10, 10, 80, 25);

    panel.add(costLabel);



    JTextField costText = new JTextField(20);

    costText.setBounds(100, 10, 160, 25);

    panel.add(costText);





    JButton storeGearButton = new JButton("Store");

    storeGearButton.setBounds(10, 80, 80, 25);

    panel.add(storeGearButton);



    this.add(panel, BorderLayout.NORTH);

}

public static void main(String args) {



    AddSomethingFrame app= new AddSomethingFrame(application);

    app.setVisible(true);

   }

}
