How do I convert a Groovy String collection to a Java String Array?

Question

I\'m trying to call a methond on a Java class from a Groovy class. The Java method has a String array as a parameter, and I have a collection of Strings in my Groovy class. Ho

Just try casting like this:

def data = ["a","b","c"] as String[]
