It's called "varargs":
http://docs.oracle.com/javase/1.5.0/docs/guide/language/varargs.html
It's a feature of Java 1.5+ and has been around for nearly a decade.

OK...
(Params... params)
"..." means variable length of parameters.
Moreover doInBackground a method to do the process intensive work in non-ui thread, present in SwingWorker class Java, and in AsyncTask<> in Android.
