    public static void main(String[] args) {
        JFrame frame = new JFrame("Add Elements to JList Example");
        frame.setLayout(new BorderLayout());

        JTextField textField1 = new JTextField(20);
        JLabel label1 = new JLabel("Element 1:");
        JPanel panel1 = new JPanel();

        JLabel label2 = new JLabel("Element 2:");
        JPanel panel2 = new JPanel();
        panel2.add(label2);
        panel2.add(textField2);

        DefaultListModel<String> listModel = new DefaultListModel<>();
        JList<String> list = new JList<>(listModel);

        JButton addButton = new JButton("Add Elements");
        addButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                String element1 = textField1.getText();
                String element2 = textField2.getText();

                listModel.addElement(element1);
                listModel.addElement(element2);

                textField1.setText("");
                textField2.setText("");
            }
        });

        frame.add(panel1, BorderLayout.NORTH);
        frame.add(panel2, BorderLayout.CENTER);
        frame.add(new JScrollPane(list), BorderLayout.SOUTH);
        frame.add(addButton, BorderLayout.EAST);

        frame.setSize(400, 300);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);
    }
}
