updating a panel I am designing a program for my assignment using java. I have made a log on box where user enters name and password and clicks on submit or register. Once clicked, an optionpane is brought 

upEX.(JOptionPane.showMessageDialog(null, "Account registered", "Account", 
    JOptionPane.INFORMATION_MESSAGE);)

I was wondering how can I add an action listener to the OK button in the option pane that would remove all contents (username,pass,2btns) and replaces it with something else? I found this link: updating a panel which basically just says to use frame.remove and then add.

Another question: My java file looks something like this

class MainFrame extends JFrame {

  public MainFrame() {
    // All the log in panels buttons are here, etc
  }
}

I was wondering if it would be efficient to add the new box details in the same area or make a new class?

Don't. Allow the dialog to close, ascertain the action the user took, show another dialog...

Better yet, create you own JPanel, use a CardLayout, add all your views to it and navigate between them. Place this on an instance of a JFrame...

See How to Use CardLayout for more details

It would depend. A Class should be a self contained unit of work, focused on accomplishing it's designed task...if your main class is doing more work then it should, then yes, separate the logic into separate class
