What do I put in the third line at the "?"

Not getting what I should put here... tried comparing to what I made in the previous video but still not getting it.

Array.java 
String[] sports = { "Basketball", "Baseball", "Tennis" };
String bestSport = sports[0];
int numberOfSports = ?[sports.length];

As Zack said you can use array.length when using Java arrays.

String[] array = new String[10];
int size = array.length;

Thanks... seems I was over thinking it... I ended up with

int numberOfSports = sports.length;

and that passed muster.

Java's not my language, but in C++ it would be just sports.length (or something like that), without the [ ]'s.

int num = someString.length; (or length() ? )
