需要登录项目的帮助（JAVA）

Question

我有一个名为login的按钮，带有if和else。不知何故，当if为false而不是else语句时，以及当我没有在JTextField中放入任何信息时，它仍然运行，没有显示任何错误

以下是代码：

        public static void main(String [] args){

    JFrame frame = new JFrame();
    frame.setTitle("User Log In");
    frame.setSize(500,300);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);


    //Labeling

    JLabel title = new JLabel("Please Log In");
    frame.add(title);
    JLabel user = new JLabel("UserName:");
    frame.add(user);
    JLabel pass = new JLabel("Password:");
    frame.add(pass);


      // Set the location on the frame

      title.setBounds(200, -25, 120, 145);
      user.setBounds(150,50,100,50);
      pass.setBounds(150,90,100,50);



      //Input Border

      JTextField userField = new JTextField();
      frame.add(userField);
      userField.setBounds(250,65,80,20);

      JPasswordField passField = new JPasswordField();
      frame.add(passField);

      passField.setBounds(250,105,80,20); 


      //Button

      JButton but1 = new JButton("LOGIN");
      frame.add(but1);
      but1.addActionListener(new Action());
      but1.setBounds(200,150,100,20);

}
      static class Action implements ActionListener{

          public void actionPerformed (ActionEvent e){

            int password = 1234;

            if (password == 1234){


                    JFrame  frame = new JFrame();
                    frame.setVisible(true);
                    frame.setSize(500,300);
                    JLabel label = new JLabel("Welcome To My Game");
                    frame.setLocationRelativeTo(null);
                    JPanel panel = new JPanel();
                    frame.add(panel);
                    panel.add(label);     

                      }
                      else  {
                            JOptionPane.showMessageDialog(null, "Incorrect Password Try Again");

                      }

          }


      }

您将密码初始化为默认值1234，因为它总是运行。。改变它
