我有两个JTextfields,我希望第二个Textfield的值/文本根据第一个TextField中的值/文本的任何变化而改变

这就是我在做的事情

    textField_15 = new JTextField("100");
    textField_15.setEditable(false);
    textField_15.setColumns(10);
    textField_15.setBounds(161, 253, 86, 20);
    panel_3.add(textField_15);

    textField_14 = new JTextField();
    textField_14.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent arg0) {
            int az = Integer.parseInt(textField_14.getText());
            int aw = Integer.parseInt(textField_15.getText());
            int aq = aw - az;
            String ar = String.valueOf((aq));
            JOptionPane.showMessageDialog(null, az + " " +aw + " " + aq + " " + ar);
            textField_15.setText(ar);
        }
    });
    textField_14.setColumns(10);
    textField_14.setBounds(426, 186, 86, 20);
    panel_3.add(textField_14);
