Help with a simple login Gui

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class Login{
	String Username = "james3302";
	String Password = "pass";
	String msg = " ";
	
	
	public static void main(String[] args){
		Login gui = new Login();
		gui.go();
	}
	public void go(){
		JFrame frame = new JFrame();
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		JPanel panel = new JPanel();
		JLabel lblUsername = new JLabel("Username:");	
		JLabel lblPassword = new JLabel("Password:");
		JTextField txtUsername = new JTextField(20);
		JTextField txtPassword = new JTextField(20);
		JButton btnLogin = new JButton("Login");
		btnLogin.addActionListener(new LoginListener());
		JButton btnCancel = new JButton("Cancel");
		btnCancel.addActionListener(new CancelListener());
	

		panel.add(lblUsername);
		panel.add(txtUsername);
		panel.add(lblPassword);
		panel.add(txtPassword);			
		frame.getContentPane().add(BorderLayout.CENTER,panel);



		frame.setSize(300,300);
		frame.setVisible(true);


	}

	public class LoginListener implements ActionListener{
		public void actionPerformed(ActionEvent event){
			if(username.equals(txtUsername.getText())){
				if(password.equals(txtPassword.getText())){
					msg = "Login Granted!";
				}else{
					msg = "Login Denied";
				}
			}else{
				msg = "Login Denied";
			}	
			JOptionPane.showMessageDialog(null,msg);					
		}
	}
	public class CancelListener implements ActionListener{
		public void actionPerformed(ActionEvent event){
			txtUsername.setText = " ";
			txtPassword.setText = "";
			txtUsername.requestFocus();
		}
	}
}

I get compile errors saying "cannot find symbol txtUsername" Also cannot find txtPassword, username, or password.

txtUsername is declared inside the go() method. if you are not in that method, the variable doesn't exist. Same for the others.

you probably want to declare them as member variables, then set them inside your go() method... something like:

    
public class Login{
   String Username = "james3302";  
   String Password = "pass";  
   String msg = " ";  
   
   JTextField txtUsername = null;


public void go(){  
   txtUsername = new JTextField(20);  
}

Thanks that worked, I also rename username to strUsername and password to str Password(thinking they were reserved words). And changed txtUsername.setText = ""; to
txtUsername.setText("");

Now it runs yea!
