如何在JVM上确定任意格式(JPEG,PNG等)图像文件的尺寸？

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class ImageSize {
    public static void main(String[] args) {
        try {
            File file = new File("path/to/image");
            BufferedImage image = ImageIO.read(file);
            int width = image.getWidth();
            int height = image.getHeight();
            System.out.println("Image dimensions: " + width + " x " + height);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
