That's just blue, white and red colored rectangles. If you're using the forms designer, you can add and size three Panel containers with different background colors side-by-side in a larger Panel that represents the whole flag.
Writing your own Swing code is easy on this one. First, I'd make a utility class to represent one flag panel (declared static because I have it inside my application class):
static class FlagPanel extends JPanel {
public FlagPanel( int width, int height, Color color ) {
Dimension size = new Dimension(width, height);
setMaximumSize(size);
setMinimumSize(size);
setPreferredSize(size);
setBackground(color);
}
} // FlagPanel class
Not much to it, huh? That class is actually generally useful for creating fixed-size colored panels for any purpose. Then you can make the container panel with:
JPanel flagPanel = new JPanel();
flagPanel.setLayout(new BoxLayout(flagPanel, BoxLayout.X_AXIS));
flagPanel.add(new FlagPanel(200, 400, new Color(0,85,164)));
flagPanel.add(new FlagPanel(200, 400, new Color(255,255,255)));
flagPanel.add(new FlagPanel(200, 400, new Color(250,60,50)));
Those colors are (according the Wikipedia) the official RGB colors from the flag of France, by the way, and the 600x400 overall size fits the 3:2 aspect ratio too. See:
