JAVA实现截屏小Demo

闲的没事,写个从书上看到的一个小例子,java获取电脑屏幕内容,类似于qq截图吧。直接上代码,都有注释比较简单。

public class ScreenPhoto {
	public static void main(String[] args) throws AWTException, IOException {
		// 获取屏幕尺寸大小
		Dimension size = Toolkit.getDefaultToolkit().getScreenSize();
		Rectangle rectangle = new Rectangle(size);
		Robot robot = new Robot();
		// 截取屏幕
		BufferedImage image = robot.createScreenCapture(rectangle);
		File screenFile = new File("D:");
		if (!screenFile.exists()) {
			screenFile.mkdir();
		}
		File f = new File(screenFile, "1.png");
		// 写入文件
		ImageIO.write(image, "png", f);
		// 自动打开
		if (Desktop.isDesktopSupported() && Desktop.getDesktop().isSupported(Desktop.Action.OPEN))
			Desktop.getDesktop().open(f);
	}
}

最后贴一张效果图
