How to check if a folder exists

Question

I am playing a bit with the new Java 7 IO features, actually I trying to receive all the xml files of a folder. But this throws an exception when the folder does not exist, how can I check if the folder exists with the new IO?

public UpdateHandler(String release) {

    log.info("searching for configuration files in folder " + release);

    Path releaseFolder = Paths.get(release);

    try(DirectoryStream<Path> stream = Files.newDirectoryStream(releaseFolder, "*.xml")){

        for (Path entry: stream){

            log.info("working on file " + entry.getFileName());

        }

    }

    catch (IOException e){

        log.error("error while retrieving update configuration files " + e.getMessage());

    }

}

You need to transform your Path into a File and test for existence:

for(Path entry: stream){

  if(entry.toFile().exists()){

    log.info("working on file " + entry.getFileName());

  }

}
