JavaNote 3.7 截图并存储指定位置

一、java代码

public class ScreenShot {
    public static void main(String args[]){
        ScreenShot screenShot = new ScreenShot();
        try {
            screenShot.captureScreen("D:\\pictures");
        }
        catch (Exception e){
            e.getMessage();
        }
    }
    public void captureScreen(String path) throws Exception {
        //格式化图片名称
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyyddMMhhmmss", Locale.CHINESE);
        String name = simpleDateFormat.format(new Date()).toString()+".png" ;
        File dir = new File(path);
           if(!dir.exists()){
               dir.mkdirs();
       }
        File file = new File(path + "\\" + name);
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();//获得屏幕高度和宽度
        Rectangle screenRectangle = new Rectangle(screenSize);//指定一个坐标区域
        Robot robot = new Robot();
        BufferedImage image = robot.createScreenCapture(screenRectangle);
        ImageIO.write(image, "png", file);
    }
}
