private static final int WindowWidth = 777; //its 777 pixels wide

} catch (IOException e) {
}//end of try/catch
f.setResizable(false); //not to be resized
f.setIconImage(image);
f.setSize(WindowWidth, WindowHeight); //size fixed by size of display and borders
f.setLocation(0, 0); //start top left
f.setLayout(new BorderLayout()); //north south east west and centre
