Stuck on android code challenge

Hi i'm stuck on this

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

String[] sports = { "Basketball", "Baseball", "Tennis" };
String bestSport = sports[0];
int numberOfSports = (sports.length);

Hi Phil,

From the code provided and have had looked at the challenge this is what you would need to do

Declare a string variable called lastSport and then assign it to the last or 3rd element (index 2) of the array i.e.

String lastSport = sports[2]; //since index 2 or element no 3 or Tennis is the last sport in the array

This should have been easy since you have already defined the first sport in the array with index [0]

Alternatively a second better way to do this challenge

String[] sports = { "Basketball", "Baseball", "Tennis" };
String bestSport = sports[0];
// int numberOfSports = (sports.length);    ... No need to put sports.length in brackets
int numberOfSports = sports.length;
String lastSport = sports[numberOfSports-1];

Reason : sports.length will give the value 3 since there are three elements. This value is now stored within numberOfSports

Now since index numbers start from 0 so the last value in an array will by convention be length of array - 1

Array

Hope this explains. Ask again if it doesn't
