Cant solve this array task for android

String[] sports = { "Basketball", "Baseball", "Tennis" };

// TASK 1:
String bestSport = sports[0];
// here you are creating a new String variable "bestSport"
// then you assigning a value to this new String variable
// this value is the first String ("Basketball") from the array above
// arrays are zero based, so every String inside the array is counted from 0 to ....
// so "Basketball" is count 0
// "Baseball" is count 1
// and "Tennis"  is count 2 
// and so on


// TASK 2:
int numberOfSports = sports.length;
// here you are creating a second variable
// it is a Integer (int) so it stores numbers
// the method length (no parenthesis) can be used on arrays
// and our array is called sports
// so sports.length; returns a number 3 (three Strings inside the array)
// and stores it inside our numberOfSports variable that takes a number of elements inside the sports array.

String lastSport = sports[2];
// so the last String inside the array is on place 2
