GraphicsEnvironment
also declares a
GraphicsDevice[]
getScreenDevices()
method that returns an array of
GraphicsDevice
in-
stances. Each instance describes an image buffer, printer, or
raster screen
(a screen of
pixels) that's available to the application. (Because image buffers and printers are not
screens,itwouldhavebeenlessconfusingtohavenamedthismethod
getGraphic-
sDevices()
.)
