New Panel not showing up

[zuber]

This is probably me missing something simple, but I can't seem to get my choice boxes to appear on screen (note that if you click where they should be, they do appear, one at a time)

code:

public void writeQuizFromFile (String name) throws IOException     {         BufferedReader input = new BufferedReader (new FileReader (name));         String[] question = new String [5];         JRadioButton[] [] choice = new JRadioButton [4] [5];         ButtonGroup group[] = new ButtonGroup [5];         JPanel quizPanel = new JPanel (new GridLayout (10, 10));         String temp;         for (int j = 0 ; j < 5 ; j++)         {             question [j] = input.readLine ();             group [j] = new ButtonGroup ();             for (int k = 0 ; k < 4 ; k++)             {                 temp = input.readLine ();                 choice [k] [j] = new JRadioButton (temp);                 choice [k] [j].setActionCommand (temp);                 group [j].add (choice [k] [j]);                 choice [k] [j].addActionListener (this);                 quizPanel.add (choice [k] [j]);             }         }         quizPanel.add (button [9]);         button [9].setVisible (true);         panel.setVisible (false);         getContentPane ().add (quizPanel);         quizPanel.show ();           }

Any thoughts as to how I make them appear?

Never mind, just realized I was using JPanel instead of Panel, problem solved
