Java GridLayout 图像大小

Question

我正在制作一个程序，它会询问您的姓名和年龄，根据您的回答，它会输出一个文本短语和适当的图像，但我的问题是我无法控制网格布局中组件的大小，因此图片顶部被切掉了，所以我只能看到一小部分

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);
            }
        }
    }

这就是我到目前为止所拥有的，我正在尝试控制组件的高度，认为它只会使该部分更大，因为宽度已经很好了。

尝试通过 getIconHeight() 和 getIconWidth() 获取图像大小，然后通过调用 public void setSize(Dimension d) 使用这些值设置 JLabel 的大小，告诉我这是否有效。
