Hi,

How can I get screen resolution in Java?

Answer 1

You can use AWT Toolkit,

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
double width = screenSize.getWidth();
double height = screenSize.getHeight();

or better java2d, which supports multi monitor setups:

GraphicsDevice gd = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
int width = gd.getDisplayMode().getWidth();
int height = gd.getDisplayMode().getHeight();

Answer 2

You can determine the screen resolution (screen size) using the Toolkit class. This method call returns the screen resolution in pixels, and stores the results in a Dimension object, as shown here:

Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();

You can then get the screen width and height as int's by directly accessing the width and height fields of the Dimension class, like this:

screenHeight = screenSize.height;
screenWidth = screenSize.width;
