This method does not check that the path given is actually a directory. If a path to a normal file is given, it will throw a <code>NullPointerException</code>.
<lang java5>import java.nio.file.Paths;

public static boolean isEmptyDir(String dirName){
return Paths.get(dirName).toFile().listFiles().length == 0;
