Here is the code to resize an Image

private BufferedImage resizeImage(File imageFile) {
   int width = 250;
   int height = 250;

   BufferedImage image = null;
   try {
      image = ImageIO.read(imageFile);
   } catch (IOException e) {

   }

   BufferedImage resizedImage = new BufferedImage(width, height, image.getType());
   Graphics2D g = resizedImage.createGraphics();
   g.drawImage(image, 0, 0, width, height, null);
   g.dispose();
   return resizedImage;
}

To write an image as file

ImageIO.write(image, extension, file);

image --> RenderedImage; My case this is BufferedImage
extension --> file type
file --> your output file object
