Java uses the Java runtime method to get the current screenshot

To save the screenshot picture to a local path:

 Packagecom.test;Importjava.awt.AWTException;Importjava.awt.Dimension;Importjava.awt.HeadlessException;ImportJava.awt.Rectangle;ImportJava.awt.Robot;ImportJava.awt.Toolkit;ImportJava.awt.image.BufferedImage;ImportJava.io.File;Importjava.io.IOException;ImportJavax.imageio.ImageIO; Public classMainrun {/**     * @paramargs*/     Public Static voidMain (string[] args) {Try{Dimension Dimension=Toolkit.getdefaulttoolkit (). Getscreensize (); BufferedImage screenshot= (NewRobot ()). Createscreencapture (NewRectangle (0,                    0, (int) Dimension.getwidth (), (int) (Dimension.getheight ())); File File=NewFile ("C:/screen.jpg"); Imageio.write (screenshot,"JPG", file); } Catch(headlessexception e) {//TODO auto-generated Catch blockE.printstacktrace (); } Catch(awtexception e) {//TODO auto-generated Catch blockE.printstacktrace (); } Catch(IOException e) {//TODO auto-generated Catch blockE.printstacktrace (); }    }}

Web version, which will show the live picture as a stream back to the page:
