which is better setExtendedState(JFrame.MAXIMIZED_BOTH) or GraphicsDevice device?

I am planning on making a full screen application in Java. I have come across 2 sets of ways to make the application full screen.

1. frame.setExtendedState(JFrame.MAXIMIZED_BOTH)
2. GraphicsDevice device = GraphicsEnvironment.getLocalGraphicsEnvironment().getScreenDevices()[0];
    device.setFullScreenWindow(frame);

Both of these do the same that is make the frame full screen. What I would like to know which of these are better? If I was to use this application on different screen resolution would they behave the same .Example projectors etc

Approach 2. is preferred. The best thing to do is check if fullscreen mode is available:

if (device.isFullScreenSupported()) {
    device.setFullScreenWindow(frame);
} else {
    frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
}

Maximizing a frame is the equivalent of double-clicking the title bar. It will not fill the parts of the screen used by the desktop's taskbar or other reserved areas, and its decorations (title bar, border, close/minimize/maximize buttons) will still be visible, which probably is not what you want.
