条件是不检查。 Java, AWT

The condition is not checking. Java, AWT

我正在 Java 使用 AWT 编写一个小型登录表单。在检查用户登录输入时遇到问题:我需要,当用户输入 "admin" 作为登录名和 "password" 作为密码时,程序输出 "Succes!",但无论如何我都会收到 "Wrong!" 消息, 即使输入的数据满足条件。

那么,我应该怎么做才能使程序正确检查条件?

代码:

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);
    }
}

只需尝试 .equals() 而不是 ==
