Try this,

For Single Screen

Toolkit tool = Toolkit.getDefaultToolkit();
Dimension dim = tool.getScreenSize();
int screenWidth = dim.getWidth();
int screenHeight = dim.getHeight();

For Multiple Screen

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gs = ge.getScreenDevices();


// Get size of each screen

for (int i=0; i<gs.length; i++) {
    DisplayMode dm = gs[i].getDisplayMode();
    int screenWidth = dm.getWidth();
    int screenHeight = dm.getHeight();
}
