I am writing a small login form at Java using AWT. Faced a problem while checking user input for login: I need, when user inputed "admin" as login and "password" as password, program outputting "Succes!", but anyway I get "Wrong!" message, even if inputed data meet the condition.
So, what should I do so that the program checks the condition correctly?
Code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Login extends JFrame {
private JButton button = new JButton("Confirm");
private JLabel label1 = new JLabel("Login:");
private JTextField login = new JTextField("", 8);
private JLabel label2 = new JLabel("Password:");
private JTextField pswrd = new JTextField("", 8);
public Login() {
super("Please log in");
this.setBounds(100, 100, 250, 100);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container container = this.getContentPane();
container.setLayout(new GridLayout(3,2,2,2));
container.add(label1);
container.add(label2);
container.add(login);
container.add(pswrd);
button.addActionListener(new ButtonEvent());
container.add(button);
}
class ButtonEvent implements ActionListener {
public void actionPerformed(ActionEvent e) {
if (login.getText() == "admin" && pswrd.getText() == "password")
{
JOptionPane.showMessageDialog(null, "Succes!", "Output", JOptionPane.PLAIN_MESSAGE);
}
else
{
JOptionPane.showMessageDialog(null, "Wrong!", "Output", JOptionPane.PLAIN_MESSAGE);
}
}
}
public static void main(String[] args) {
Login app = new Login();
app.setVisible(true);
}
}
