您好,我是 Java Swing 应用程序窗口的初学者 在这里,我在图形中遇到了这个问题。
- 为什么会出现这个问题?

这是代码

private JFrame frame;
private JTextField textField;
private JPasswordField passwordField;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
MainWindow window = new MainWindow();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public MainWindow() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
JButton btnLogin = new JButton("Login");
btnLogin.addActionListener(new ActionListener() {
private String txtUsername;
private String txtPassword;
public void actionPerformed(ActionEvent arg0) {
txtPassword = passwordField.getText();
txtUsername = textField.getText();
}
});
btnLogin.setBounds(183, 181, 89, 23);
frame.getContentPane().add(btnLogin);
textField = new JTextField();
textField.setBounds(183, 110, 150, 23);
frame.getContentPane().add(textField);
textField.setColumns(10);
JLabel lblNewLabel = new JLabel("Username");
lblNewLabel.setBounds(106, 114, 94, 14);
frame.getContentPane().add(lblNewLabel);
JLabel lblNewLabel_1 = new JLabel("Password");
lblNewLabel_1.setBounds(106, 153, 67, 14);
frame.getContentPane().add(lblNewLabel_1);
passwordField = new JPasswordField();
passwordField.setBounds(183, 147, 150, 23);
frame.getContentPane().add(passwordField);
JLabel lblNewLabel_2 = new JLabel("Bus Station");
lblNewLabel_2.setHorizontalAlignment(SwingConstants.CENTER);
lblNewLabel_2.setFont(new Font("Tahoma", Font.PLAIN, 25));
lblNewLabel_2.setBounds(62, 11, 321, 51);
frame.getContentPane().add(lblNewLabel_2);
}
}
