[HDGEM] How to convert Set to String[] in Java

Use the Set#toArray(T[]) method taking a typed array argument of the same size.

String[] myArray = myset.toArray(new String[myset.size()]);

A different size can also, but that would force the toArray() method to create a new array to return instead of reusing the provided argument, which may end up to be less efficient.
