How can one get the screen resolution (width x height) in pixels?
I am using a JFrame and the java swing methods.
You can get the screen size with the Toolkit.getScreenSize() method.
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
double width = screenSize.getWidth();
double height = screenSize.getHeight();
On a multi-monitor configuration you should use this :
GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
int width = gd.getDisplayMode().getWidth();
int height = gd.getDisplayMode().getHeight();
If you want to get the screen resolution in DPI you'll have to use the getScreenResolution() method on Toolkit.
