Code challenge help with ParseQuery in Background

I'm trying to execute the following question

Now we can execute the query in the background. Call the correct method to do so, and for the parameter, declare a new FindCallback (which requires the same type parameter as query). For now just leave the body of the callback blank (i.e. just use curly braces: { }).

Frustratingly the question itself is very confusing. I'd like to finish off each quiz before moving to next lesson.

TTH, please break down the question or provide plain instructions as your web is being used by international users too.

figured the answer myself. Seems I need to work on my English :S

query.findInBackground(new FindCallback<String>() {});

The following worked for me:

query.findInBackground(new FindCallback<ParseObject>() {} );

I was stuck too for a long time but in my case it was because I typed FindCallBack instead of FindCallback.

you can try out the following stages: ParseQuery<String> query = new ParseQuery<String>("DoctorWhoEpisodes"); query.whereEqualTo("writer", "Neil Gaiman"); query.findInBackground(new FindCallback<String>() { }).
