The Toolkit class will has methods to get the screen size as well as the screen resolution, based on which you can compute the Monitor size.

i'm calculateing like this but i think it is not giveing exact value if i change the resolution of dispaly
Dimension screen = java.awt.Toolkit.getDefaultToolkit().getScreenSize();
int pixelPerInch=java.awt.Toolkit.getDefaultToolkit().getScreenResolution();
double height=screen.getHeight()/pixelPerInch;
double width=screen.getWidth()/pixelPerInch;
double x=Math.pow(height,2);
double y=Math.pow(width,2);
jLabel1.setText("Res"+screen.getHeight()+"X"+screen.getWidth()+"Pixel/Inch"+pixelPerInch+" "+x+" "+y+"="+Math.sqrt(x+y));

What do you think is wrong with it? I've just run it and seem to get realistic output.

I assume you're not expecting an exact answer like 15 inches - a 15 inch monitor will have an actual screen size of slightly less.
