使用java swing创建一个包含两个文本框、一个文件选中按钮、一个密码框、一个提交按钮的UI程序，其中第二个文本框的值由点击文件选择按钮后获取到选中文件的绝对路径

以下是一个简单的Java Swing程序，其中包含两个文本框、一个文件选中按钮、一个密码框和一个提交按钮。点击文件选择按钮后，将获取选中文件的绝对路径，并将其填充到第二个文本框中。

public class FileChooserExample extends JFrame implements ActionListener {

    private JTextField textField1;
    private JTextField textField2;

        super("File Chooser Example");

        // Create components
        JLabel label1 = new JLabel("Text Field 1:");
        textField1 = new JTextField(20);
        JLabel label2 = new JLabel("Text Field 2:");
        textField2 = new JTextField(20);
        passwordField = new JPasswordField(20);
        fileChooserButton = new JButton("Choose File");
        submitButton = new JButton("Submit");

        // Set file chooser button action listener
        fileChooserButton.addActionListener(this);

        // Set submit button action listener
        submitButton.addActionListener(this);

        // Create layout
        JPanel panel = new JPanel(new GridLayout(4, 2));
        panel.add(label1);
        panel.add(textField1);
        panel.add(label2);
        panel.add(textField2);
        panel.add(new JLabel("Password:"));
        panel.add(passwordField);

        setContentPane(panel);
        pack();
        setVisible(true);
    }

    // Handle button clicks
    public void actionPerformed(ActionEvent e) {

                textField2.setText(selectedFile.getAbsolutePath());
            }
        } else if (e.getSource() == submitButton) {
            // Handle submit button click
            String value1 = textField1.getText();
            String value2 = textField2.getText();
            char[] password = passwordField.getPassword();
            // Do something with the values and password
            System.out.println("Value 1: " + value1);
            System.out.println("Value 2: " + value2);
            System.out.println("Password: " + new String(password));
        }
    }

    public static void main(String[] args) {
        new FileChooserExample();
    }
