Why Resource path is coming null in Windows by Java code? -

i writing path of file

if (!new file(path).exists()) {         url location = this.getclass().getclassloader().getresource(path);         if (location == null) {             location = thread.currentthread().getcontextclassloader().getresource(path);         }         path = location.getpath();         path = urldecoder.decode(path, "utf-8");         path = new file(path).getpath();          if (!new file(path).exists()) {             throw new exception("unable resolve path: " + path);         }     }
