Let's continue with our previous code challenge. Execute the query that we built before using the findInBackground() method. Pass in the mFindCallback variable defined below.
// This code is an excerpt from an Activity. Some code has been omitted!
FindCallback<ParseUser> mFindCallback = new FindCallback<ParseUser>() {
@Override
public void done(List<ParseUser> users, ParseException e) {
if (e == null) {
}
}
};
ParseQuery<ParseUser> query = ParseUser.getQuery();
query.orderByAscending("email");
query.findInBackground(new FindCallback<ParseUser>()); {

query.findInBackground(mFindCallback);
as you have already created the new FindCallback<ParseUser>() and stored it in a variable called mFindCallback
