我的代码有问题。具体这个。当我在 Netbeans 中编译它时,它显示“无法找到或加载主类表单”,但我在代码中看到了它……我做错了什么?
其次,要将它嵌入到网页中,我可以编译它吗?谢谢您的帮助。我对 Java GUI 的东西只有一周的了解。

class Form {
private static void display() {
JTextField field1 = new JTextField();
JTextField field2 = new JTextField();
JTextField field3 = new JTextField();
JTextField field4 = new JTextField();
JTextField field5 = new JTextField();
JPanel panel = new JPanel(new GridLayout(0, 1));
panel.add(new JLabel("Username:"));
panel.add(field1);
panel.add(new JLabel("Password:"));
panel.add(field2);
panel.add(new JLabel("Repeat Password:"));
panel.add(field3);
panel.add(new JLabel("Email address:"));
panel.add(field4);
panel.add(new JLabel("Repeat email address:"));
panel.add(field5);
int result = JOptionPane.showConfirmDialog(null, panel, "Form",
JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
display();
}
});
}
}
