这是我的解决方案JTextField username = new JTextField();JTextField password = new JPasswordField();Object[] message = { "Username:", username, "Password:", password};int option = JOptionPane.showConfirmDialog(null, message, "Login", JOptionPane.OK_CANCEL_OPTION);if (option == JOptionPane.OK_OPTION) { if (username.getText().equals("h") && password.getText().equals("h")) { System.out.println("Login successful"); } else { System.out.println("login failed"); }} else { System.out.println("Login canceled");}
