我是Java编程的新手，但我想要做的是通过HtmlUnit使用java从网站获取一些数据，我成功地设法做到了，但我需要在JTable中表示这些数据，那就是我搞不清楚了。我有一个Login类，它是我的gui和Nova类，其中实际提取数据。
public class login {
private String novaUser;
private String novaPass;
private Nova myNova;
private JFrame frame;
private JTextField novaUsername;
private JPasswordField novaPassword;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
login window = new login();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public login() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 758, 440);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
frame.getContentPane().add(panel, BorderLayout.CENTER);
panel.setLayout(new GridLayout(0, 2, 0, 0));
JLabel lblNovausername = new JLabel("NovaUserName");
panel.add(lblNovausername);
novaUsername = new JTextField();
panel.add(novaUsername);
novaUsername.setColumns(10);
JLabel lblNovapassword = new JLabel("NovaPassword");
panel.add(lblNovapassword);
novaPassword = new JPasswordField();
panel.add(novaPassword);
JButton proceedButn = new JButton("Proceed");
proceedButn.addActionListener(stuff -> onPress());
}
//button method
private void onPress() {
// TODO Auto-generated method stub
novaUser = novaUsername.getText();
char[] inputNova = novaPassword.getPassword();
novaPass = "";
for (int i1 = 0; i1 < inputNova.length; i1++) {
novaPass = novaPass + inputNova[i1];
}
if(novaPass != "" && novaUser!= ""){
try{
myNova = new Nova();
myNova.NovaConnection(novaUser, novaPass );
}
catch (Exception e){
JOptionPane.showMessageDialog( novaUsername, this, e.getMessage(), 0);
return;
