Create a button that says "submit." * If the username is at least 6 characters long (hint-- review Chapter 7 String class methods) and the passwords match (same hint), display a label that says "Your account has been created." * Otherwise, display an appropriate message. Name the file AccountCreate.java Extra (optional): Also create a text field for the users age. If it's less than 13, display "Sorry. You must be 13 or older to use this site."

//public JFrame frame; //Extends JFrame already so 'this' IS a frame
public JPasswordField passwordField;
public JTextField textField;
public JButton blogin;
public JButton btnNewUser;

/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Login window = new Login();
window.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}

/**
* Create the application.
*/
public Login() {
initialize();
}

/**
* Initialize the contents of the frame.
*/
public void initialize() {

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); //DO NOT forget this, the instance will continue to run if not.
setLayout(null);

setSize(350,300); // only added so I didn't have to expand window as often

passwordField = new JPasswordField();
passwordField.setBounds(90, 114, 105, 22);
add(passwordField);

textField = new JTextField();
textField.setBounds(90, 79, 105, 22);
add(textField);
textField.setColumns(10);

JLabel lblUsername = new JLabel("Username");

try {
//sc = new Scanner(new File("Logincode.txt")); not used
scan = new Scanner(new File("Change to the path where your file is located ofcourse")); //make sure to add your path

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

//Scanner keyboard = new Scanner (System.in);   

//String inpUser = keyboard.nextLine();
String inpUser;
inpUser = textField.getText();

//String inpPass = keyboard.nextLine();
String inpPass;
inpPass = passwordField.getText();// gets input from user

String user="";
if(scan.hasNextLine()) //added to check if there is another line to read
user = scan.nextLine();

String pass="";
if(scan.hasNextLine())
pass = scan.nextLine(); // looks at selected file in scan

if (inpUser.equals(user)&& inpPass.equals(pass)){
System.out.print("your login message");
