There is more to it than that. Windows keeps a DPI setting but it doesn't really reflect the actual size of the screen in inches. On my XP computer the DPI setting is 96 dots per inch and that is what is returned by Toolkit.getScreenResolution(). My screen is set for 1024x768 and it is 13 1/4 inch by 10 3/4 inch. At 96 DPI the screen should be 10 2/3 x 8 inches. As far as I know there is no way to actually determine how many pixels will make up an inch on your display.
