Declare a String variable named lastSport and initialize it with the last element of the sports array.

Does not work using: String bestSport = ""; String[] sports = { bestSport, "Basketball", "Baseball", "Tennis" }; int numberOfSports = sports.length; String lastSport = sports[numberOfSports];

In your code, the number stored in numberOfSports is 4 (bestSport, basketball, baseball, & tennis). If you did sports[numberOfSports] you would be calling the sports[4] which is nonexistant because there is no 5th spot in the array.

Therefor you have to do: sports[numberOfSports - 1];

String[] sports = { "Basketball", "Baseball", "Tennis" };
String bestSport = sports[0];
int numberOfSports = sports.length;
String lastSport = sports[sports.length - 1];

Hi Yord,

Kate has given a good answer. By convention this is the right way. However as it's evident from the question, there are only three values for the array. So you could have also written

String lastSport = sports[2];   // where 2 is the index of the last element

Hope it helps.
