My Jframe form does not comes up when i try to make it responsive

Question

i was trying to make my JFrame form responsive according to screen size but when try my code it doesnt comes up and if i remove the code it works fine.here is my code

Home frame = new Home();
    Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();
    int i = screen.width;
    int j = screen.height;
    frame.setSize(i, j);

please help

What values do `i` and `j` contain? (try `System.err.printf("%d / %d\n", i, j)` or use a debugger) — Andreas Fester, Feb 03 '16 at 08:45
@TsakiroglouFotis He is reading the (public) fields directly which are `int` (https://docs.oracle.com/javase/8/docs/api/java/awt/Dimension.html#height). The getters return Double though ... — Andreas Fester, Feb 03 '16 at 08:48
Maybe your dimensions exceed the screen size when title bar and stuff get added, then you may fall into this special case : http://stackoverflow.com/questions/9536804/setsize-doesnt-work-for-jframe — Arnaud, Feb 03 '16 at 08:50

To enlarge the frame to occupy the full-screen size, use:

frame.setExtendedState(JFrame.MAXIMIZED_BOTH);

To make the swing components responsive and adapting the frame size, use layout managers (e.g. FlowLayout):
