how can I get the asset path of a given rendition from in Java file in AEM?

I want to display 'cq5dam.thumbnail.140.100.png' rendition of my image asset as a thumbnail in my html page. How can I get the asset path of one of my asset in DAM in a java/JSP for a given rendition

this function will do the trick

public static String getImageAssetPath(SlingHttpServletRequest slingRequest,String actualDamPath,String renditionParam,String defaultPath) {
    try {
        if(StringUtils.isNotEmpty(actualPath)){
              Resource resource = slingRequest.getResourceResolver().getResource(actualPath);
              Asset asset = resource.adaptTo(Asset.class);
              String imageAssetPath = asset.getRendition(renditionParam).getPath();
              LOGGER.info("imageAssetPath for given rendition: " + imageAssetPath);
              return imageAssetPath;
       }

    } catch (Exception e) {
        LOGGER.error(e.getMessage());
    }

    return defaultPath;
}

put this function in a tag library so that the same can be used in your jsps

${mytaglib:getAssetPath(slingRequest,property.previewImage,'cq5dam.thumbnail.140.100.png','')}
