This challenge wants me to declare a String variable named lastSport and initialize it to the last element of my sports array.
this is my code so far... if i assign it as the last element via [3] i get outOfboundsException 3().
String[] sports = { "Basketball", "Baseball", "Tennis" };
String bestSport = sports[0];
int numberOfSports = sports.length;
String lastSport = sports[3];
After some research on stack exchange i found arrayCharToInt.length - 1 but i dont know where i need to insert this. or what to do with it if ineed to make an if loop to check equality or...? any help would be great. thanks TeamTreeHouse community. =)

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