java - Can new File() constructor return null on Android? -

i saw code in android training center website:

boolean hasexternalstorageprivatefile() {     // path file on external storage.  if external     // storage not mounted fail.     file file = new file(getexternalfilesdir(null), "demofile.jpg");     if (file != null) {         return file.exists();     }     return false; } 

does mean on android new file() can return null?

no, constructor may never return null. constructor either returns initialised object or throws exception or error.
