Trouble with declaring a string

Hello I am struck on one of the challenges and can not figure it out for the life of me. The question is.....

Declare a String variable named bestSport and initialize it to the first element of the sports array. (below is what they have given me)

String[] sports = {"basketball", "Baseball", "tennis"}:

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

Hiya,

You can declare the string with:

String bestSports;

But then you want to assign it the first element of the given array. You access those with the notiation, [index]. The array starts counting its indexes at zero.

The full declaration and initialisation will be:

String bestSports = sports[0];

I hope that makes sense.

Steve.

Hello Steve, thanks for your reply!

I have now entered String[] sports = { "Basketball", "Baseball", "Tennis" }; String bestSports; String bestSports = sports[0];

unfortunately I still have not managed to complete it?

Cheers Peter

Hiya,

I did that in two steps to illustrate.

You only need to declare the string once.

So either do

String bestSports;
bestSports = sports[0];  // <-- No 'String' preceding this

or in one line:

String bestSports = sports[0];

One declares then initialises - the second does both in one go.

Steve.
