The list of methods to do Screen Size are organized into topic(s).

Method

RectanglegetDesktopBounds()
Return the entire desktop bounds (take multi screens in account) 
Rectangle result = new Rectangle();
final GraphicsDevice[] gs = getLocalGraphicsEnvironment().getScreenDevices();
for (int j = 0; j < gs.length; j++)
    result = result.union(gs[j].getDefaultConfiguration().getBounds());
return result;
RectanglegetDesktopBounds()
get the bounds of the users desktop... 
Rectangle virtualBounds = new Rectangle();
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gs = ge.getScreenDevices();
for (int j = 0; j < gs.length; j++) {
    GraphicsDevice gd = gs[j];
    GraphicsConfiguration gc = gd.getDefaultConfiguration();
    Rectangle rect = gc.getBounds();
    if (rect != null)
...
RectanglegetLocalScreenBounds()
Gets the local monitor's screen bounds. 
GraphicsEnvironment e = GraphicsEnvironment.getLocalGraphicsEnvironment();
return e.getMaximumWindowBounds();
RectanglegetLocationFromMouse(Dimension panelPrefSize_)
get Location From Mouse 
GraphicsDevice device = MouseInfo.getPointerInfo().getDevice();
Dimension screensize = new Dimension(device.getDisplayMode().getWidth(),
        device.getDisplayMode().getHeight());
int x = (screensize.width - panelPrefSize_.width) / 2;
int y = (screensize.height - panelPrefSize_.height) / 2;
return new Rectangle(x, y, panelPrefSize_.width, panelPrefSize_.height);
RectanglegetMaximumWindowBounds()
Computes the maximum bounds of the current screen device. 
try {
    final GraphicsEnvironment localGraphicsEnvironment = GraphicsEnvironment.getLocalGraphicsEnvironment();
    return localGraphicsEnvironment.getMaximumWindowBounds();
} catch (Exception e) {
final Dimension s = Toolkit.getDefaultToolkit().getScreenSize();
return new Rectangle(0, 0, s.width, s.height);
RectanglegetMaximumWindowBounds()
get Maximum Window Bounds 
final GraphicsEnvironment localGraphicsEnvironment = GraphicsEnvironment.getLocalGraphicsEnvironment();
try {
    final Method method = GraphicsEnvironment.class.getMethod("getMaximumWindowBounds", (Class[]) null);
    return (Rectangle) method.invoke(localGraphicsEnvironment, (Object[]) null);
} catch (Exception e) {
final Dimension s = Toolkit.getDefaultToolkit().getScreenSize();
return new Rectangle(0, 0, s.width, s.height);
...
intgetMaximumWindowWidth()
get Maximum Window Width 
Toolkit toolkit = Toolkit.getDefaultToolkit();
Dimension dim = toolkit.getScreenSize();
return dim.width;
DimensiongetMaxSize(Window frame)
get Max Size 
Toolkit toolkit = Toolkit.getDefaultToolkit();
GraphicsConfiguration config = frame.getGraphicsConfiguration();
Dimension availableScreenSize = new Dimension(toolkit.getScreenSize());
Insets insets = toolkit.getScreenInsets(config);
availableScreenSize.width -= (insets.left + insets.right);
availableScreenSize.height -= (insets.top + insets.bottom);
return availableScreenSize;
DimensiongetMaxUsableScreenSize()
get Max Usable Screen Size 
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
screenSize.width = Math.min(screenSize.width, GraphicsEnvironment.getLocalGraphicsEnvironment()
        .getDefaultScreenDevice().getDisplayMode().getWidth());
screenSize.height -= 48;
return screenSize;
DimensiongetMaxWindowSize()
Gets the max window size. 
final Dimension d = getScreenDimesion();
return new Dimension((int) d.getWidth() - 100, (int) d.getHeight() - 100);
