Java GridLayout Image Size

I was making a program where it asks for your name and age and depending on your answer it would output a text phrase and an appropriate image but my problem is I cannot control the size of the components in my Grid layout so the picture is chopped off right at the top so I can only see a small portion

public class eb extends JFrame {

    private JLabel lblQuestion;
    private JLabel lblName;
    private JLabel lblAge;
    private JLabel lblAnswer;
    private JTextField txtName;
    private JTextField txtAge;
    private JButton btnEligible;
    private ImageIcon image1 = new ImageIcon("H:\\NetBeansProjects\\Skill Set 15\\Egilible.jpg");
    private JLabel ImageEligible = new JLabel(image1);
    private ImageIcon image2 = new ImageIcon("H:\\NetBeansProjects\\Skill Set 15\\Unegilible.jpg");
    private JLabel ImageUnegibile = new JLabel(image2);

    public eb() {
        setLayout(new GridLayout(7, 1)); 
        lblQuestion = new JLabel("Are you eligible to vote?");
        add(lblQuestion);
        lblName = new JLabel("Enter your Name");
        add(lblName);
        txtName = new JTextField(15);
        add(txtName);
        lblAge = new JLabel("Enter your Age");
        lblAge.setLocation(lblName.getX(), lblName.getY());
        add(lblAge);
        txtAge = new JTextField(15);
        add(txtAge);
        btnEligible = new JButton("Am I Eligible?");
        add(btnEligible);
        lblAnswer = new JLabel("Answer");
        add(lblAnswer);
        Eligible eligible = new Eligible();
        btnEligible.addActionListener(eligible);
    }

    public class Eligible implements ActionListener {

        public void actionPerformed(ActionEvent e) {
            int nAge = Integer.parseInt(txtAge.getText());
            String sName = txtName.getText();
            GridBagConstraints c = new GridBagConstraints();
            if (nAge > 18) {
                lblAnswer.setText("Step right up " + sName + ", and vote. ");
                c.fill = GridBagConstraints.VERTICAL;
                c.gridheight = 10;
                JPanel p1 = new JPanel();
                p1.add(ImageEligible, c);
                add(p1, c);
            } else {
                lblAnswer.setText("Maybe next time, " + sName);
                JPanel p2 = new JPanel();
                p2.add(ImageUnegibile, c);
                add(p2);
            }
        }
    }

This is what I have so far, I'm trying to c to control height of the component thinking it will just make that portion bigger because the width is already fine.

Don't put your answer in the same layout as the GridLayout for your form. Put it in a place that it has room to stretch.

My suggestion for your situation would be:

  • Put your form of labels and text fields in a JPanel with a GridLayout for the LayoutManager.
  • Set the contentPane of your frame to use a BorderLayout.
  • Add the form to the "PAGE_START" of your contentPane.
  • Add the answer to the "Center" of your contentPane.

Try to get sizeof image by getIconHeight() and getIconWidth() then set size of JLabel with this values by calling public void setSize(Dimension d), tell me if that worked.
