i cant seem to figure this out, or why it does this.

panel3 = new JPanel(new BoxLayout(panel3,BoxLayout.Y_AXIS));

This line of code does not work, it makes a awt error. yet when i type it this way:
panel3 = new JPanel();
panel3.setLayout(new BoxLayout(panel3, BoxLayout.Y_AXIS));

this works.
i dont get it. Can someone please explain this to me.

I don't think your Panel3 is instansiated on the first exampel. On the second example it works fine cause it has been instansiated.
