How to make full screen Java app.?

Question

I want to make a Java app. with full screen which would run correctly on all screen resolution.

I tried Toolkit in my JFrame it made my frame full screen but some its components (e.g. JButton, JTextField) were not shown when I run it on 800 x 600 screen size, but properly shown in 1600 x 900 screen size.

How to make full screen Java app. with robust component layout?

Try it :

JFrame jf = new JFrame();
jf.setExtendedState(JFrame.MAXIMIZED_BOTH); 
jf.setUndecorated(true);
jf.setVisible(true);
