Robot robot = new Robot();
robot.delay(1000);
BufferedImage screencapture = robot.createScreenCapture(
    new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));

// Save as JPEG
File file = new File("screencapture.jpg");
ImageIO.write(screencapture, "jpg", file);

흠 전혀 기대하지 않았는데 AWT가 이런 것도 지원하고 있었군..
