stack over flow error....

[alun groome]

Hi, im getting a stackoverflow error on the below scenario. Can anybody help?
Thanks in advance

public class MainApplication {
PanelA a = new PanelA();
PanelB b = new PanelB();
}
public static void main(String argv[]) {
MainApplication frame = new MainApplication();
}
}
public class PanelA
extends JPanel {
private PanelB b = new PanelB();
}
public class PanelB
extends JPanel {
private PanelA a = new PanelA();
}

What are you trying to do and can you give us the extact stacktrace?

Your main method creates an instance of MainApplication which creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. PanelA's constructor creates an instance of PanelB. PanelB's constructor creates an instance of PanelA. (and so on)
