how to convert heic image to jpg image in java

Question

I need to convert heic image to jpg image in java.

I need to perform it locally using java without any propriety package or calling external api to convert it. So far tried with twelevemonkey packages and drew packages. Either packages are not available or code that i frequently find online isn't correct below is one of the code i tried:

public class HeicToJpgConverter {

public static void main(String[] args){
    try {
        // Get the path to the HEIC/HEIF image file.
        String heicPath = "input.heic";

        // Read the image metadata.
        Metadata metadata = ImageMetadataReader.readMetadata(new File(heicPath));

        // Get the ExifIFD0 directory.
        List<com.drew.metadata.Directory> exifDirectory = (List<com.drew.metadata.Directory>) metadata.getDirectories();
        System.out.println("exifDirectory:" + exifDirectory );
        System.out.println("exifDirectory size:" + exifDirectory.size() );
        // Get the image width and height.+
        int width = exifDirectory.get(1).getInt(ExifIFD0Directory.TAG_IMAGE_WIDTH);

        int height = exifDirectory.get(1).getInt(ExifIFD0Directory.TAG_IMAGE_HEIGHT);


        // Create a new JPG image with the same width and height.
        BufferedImage jpgImage = new BufferedImage(255, 255, BufferedImage.TYPE_INT_RGB);

        // Convert the HEIC/HEIF image to JPG.
        //ImageConverter.convertHeicToJpg(heicPath, jpgImage);

        // Save the JPG image.
        File jpgFile = new File("output.jpg");
        ImageIO.write(jpgImage, "jpg", jpgFile);
    } catch (MetadataException | IOException e) {
        throw new RuntimeException(e);
    } catch (ImageProcessingException e) {
        throw new RuntimeException(e);
    }
}

following is the error

Task :HeicToJpgConverter.main() FAILED
exifDirectory:[HEIF Directory (3 tags), HEIF Directory (2 tags), File Type Directory (4 tags), File Directory (3 tags)]
