    Question I need help with METHODS!!!

    No matter how many times I've been explained the theory behind methods, I can't determine how to write them to apply to programs. Here is a simple program that work, but I need to apply 4 different methods to it.


    setUsername() – A mutator method that sets the username for the associated account. (Use any
    8 letters to represent the initial username.)

    getPassword() - An accessor method that asks for the password associated with the account.

    isUsernameValid() -This method checks whether the username entered meets the required rules
    for usernames.


    isPasswordValid() - This method checks whether the string entered is valid.




    //Using the JOptionPane class to promt the user for input
    import javax.swing.JOptionPane;
    class JavaAssignment5

    {

    public static void main(String[]args){

    //Promting the user to enter a user name and assigning it to 'x'
    String x = JOptionPane.showInputDialog(null,"Enter User Name: ", "Login", JOptionPane.QUESTION_MESSAGE);

    //Assigning 'y' as the password entered
    String y = JOptionPane.showInputDialog(null,"Password: ", "Login", JOptionPane.QUESTION_MESSAGE);

    //Setting the correct user name
    String user = new String("muzukashi");

    //Setting the correct password
    String pass = new String("Ja57pan");

    //Boolean expression to check if what the person entered is correct for both username and password
    if(user.equals(x) && pass.equals(y)){

    //Displays a message to inform them that they entered both correctly
    JOptionPane.showMessageDialog(null,"Valid user Name","Good job!", JOptionPane.WARNING_MESSAGE);
    }
    else{
    //Informs the user that they entered something wrong, but not actually telling them
    JOptionPane.showMessageDialog(null,"Invalid user Name","Dumbass", JOptionPane.WARNING_MESSAGE);
    }


    }

    }
