File f = new File("\\screen.jpg");
try {
f.createNewFile();
java.awt.Robot r = new java.awt.Robot();
Dimension dim =java.awt.Toolkit.getDefaultToolkit().getScreenSize();
Rectangle rect = new Rectangle(dim);
java.awt.image.BufferedImage img = r.createScreenCapture(rect);
java.io.FileOutputStream fw = new java.io.FileOutputStream(f);
java.io.BufferedOutputStream out = new java.io.BufferedOutputStream (fw);
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(img);
out.close();
fw.close();
} catch (Exception e) {
