Yes. The default layout of Swing root containers is BorderLayout,
and the default constraint for adding to a BorderLayout is
BorderLayout.CENTER.

If you need to - it is usually a warning that something is wrong.

But..
1) By setting the preferredSize (and to be safe,
the minimum/maximum sizes.
2) Adding the component to a layout that respects
the component's preferred size.

Have you done the layout tutorial and Swing tutorials
mentioned in the GUI FAQ?
