String[] sports = { "Basketball", "Baseball", "Tennis" }; // declaring sports as an array with those string variables
String bestSport;  // declaring a string with var name bestSport which evaluates to undefined
sports=sports[bestSport]; // assigning value sports[bestSport] to the variable sports = evaluates to undefined

I'm not sure what are you trying to do (I'm not that far yet), but your bestSport either needs a int value to get the variable out of the array or you do on the last line:

sports=sports[2]; //which assigns the string "Tennis" to your sport variable - but this overrides you array then
bestSport = sports[2]; //this would be the right answer if you are trying to take an element from the array and set it to the new variable you declared.

Give me more info so I could help you precisely. But I hope this answer is helpful.

Regards,

Nejc

I follow what your saying, but I misunderstand the assignment. Thanks

I assume the question is "Declare a String variable named bestSport and initialize it to the first element of the sports array." ?

Basically the question is asking you to create a new variable named 'bestSport' whose value is equal to the first item of the 'sports' array.

In general, this would essentially look like:

String bestSport = sports[x];

where x is the nth element in the array.

Thus, if you want get the first element, the code below the array should be

String[] sports = { "Basketball", "Baseball", "Tennis" };
String bestSport = sports[0];

Hope it helps!

You have to set the String bestSport equal to the first element of the array:

String bestSport = sports[0];
