I wrote the following code:

public class ContentUtils {
    static {
        String[] videoFormats = null;
        String[] imageFormats = null;
        try {
            Field multipartFileField = MultipartFileWrapper.class.getField("multipartFile");
            Extensions annotation = multipartFileField.getAnnotation(Extensions.class);
            imageFormats = annotation.imageFormats();
            videoFormats = annotation.videoFormats();
        } catch (NoSuchFieldException e) {
            if (imageFormats == null) {
                imageFormats = new String[]{};
            }
            if (videoFormats == null) {
                videoFormats = new String[]{};
            }
        }
        ACCEPTED_IMAGE_FORMATS = imageFormats;
        ACCEPTED_VIDEO_FORMATS = videoFormats;
    }

    public static final String[] ACCEPTED_IMAGE_FORMATS;
    public static final String[] ACCEPTED_VIDEO_FORMATS;
}

Aim of this code - read constants from annotation. Is there a way to rewrite it better?

Or something else improve at this code?

I wrote the following code to read constants from annotations:

public class ContentUtils {
    static {
        String[] videoFormats = null;
        String[] imageFormats = null;
        try {
            Field multipartFileField = MultipartFileWrapper.class.getField("multipartFile");
            Extensions annotation = multipartFileField.getAnnotation(Extensions.class);
            imageFormats = annotation.imageFormats();
            videoFormats = annotation.videoFormats();
        } catch (NoSuchFieldException e) {
            if (imageFormats == null) {
                imageFormats = new String[]{};
            }
            if (videoFormats == null) {
                videoFormats = new String[]{};
            }
        }
        ACCEPTED_IMAGE_FORMATS = imageFormats;
        ACCEPTED_VIDEO_FORMATS = videoFormats;

    public static final String[] ACCEPTED_IMAGE_FORMATS;
    public static final String[] ACCEPTED_VIDEO_FORMATS;
}
