getText() vs getPassword()

Question

I\'m currently designing a login system for a make-believe company, right now all I have is the Main login, which needs a lot of cleaning up. Below is my login handler.

Answer 1

As all the other answers have said, JPasswordField returns a char[] when you call the getPassword() method. However, the way I have it set in my sample log on form is I have a method for validating the input. I have two arrays for storing usernames[] and passwords[] and then I have my username input, and my password input. The password input in my method changes the char[] to a string before continuing, you can do so like this:

 String PasswordTyped = new String(_pwd.getPassword());

Then take that string and place that in your 'if' statement:

 if (_uid.equals("Nathan") && PasswordTyped.equals("password") {
     JOptionPane.showMessageDialog(null, "Congrats, you logged in as Nathan");
 }

However, as I mentioned my validation method runs on the two arrays of usernames[] and passwords[], while accepting a string and a char[] as input. I will copy and paste my method so you can implicate it if you would like:

public static void validate(String u, Char[] pass) {
    String password = new String(pass);
    boolean uGood = false;
    String[] usernames = new String[2];
    String[] passwords = new String[usernames.length];

    usernames[0] = "Don";
    passwords[0] = "password";
    usernames[1] = "Jared";
    passwords[1] = "password";


    for (int i = 0; i < usernames.length; i++) {

        if (usernames[i].equals(u) && passwords[i].equals(password)) {
            uGood = true;
        }
    }
    if (uGood) {
        System.out.println("Hooray, you did it!");
    }
    else {
        JOptionPane.showMessageDialog(null, "Incorrect Username\nand/or Password.");
    }
}

Finally, you would call this validation method by typing:

validate(_uid.getText(), _pwd.getPassword());
