For example I have hashMap which type is <String,Integer>
I call getKey from iterator, wanted to get String directly from the result.
But I found out that I have to call toString() to get a string type. Why is that?
Thanks.

3Please show a short but complete program demonstrating the problem. It should be fine, but we can't tell what you're doing wrong because you haven't shown us any code. My guess is that you're using the raw `Map.Entry` type, but that's only a guess at the moment. – Jon Skeet Feb 23 '15 at 20:22

You call `getKey` on *what* iterator? – Marko Topolnik Feb 23 '15 at 20:28

yes, I am using this iterator : Map.Entry pair = (Map.Entry)it.next(); is this wrong? – BufBills Feb 23 '15 at 20:30

I've already voted to close, but [here](http://stackoverflow.com/questions/2770321/what-is-a-raw-type-and-why-shouldnt-we-use-it) is what I would use as a duplicate. – Sotirios Delimanolis Feb 23 '15 at 20:32
