I all.
I have a

Map<String,Float> foo = ....

And the following line of code a couple of instructions after:

String[] fields = (String[])(foo.keySet().toArray()) ;

But at the runtime, I have a class cast exception telling me that it's
not possible to cast an Object down to a String.

How can I do to have an array of strings from the foo map key set ?

Thanks for your help.

Revisit the API and you'll find that the Set method toArray() explicitly
returns an Object array. But there's an alternative method which
returns an array of the type used in the Set. Try that one.
