java/swing: drag and drop with a list of strings

What 开发者_JAVA百科data flavor should I use to transfer a list of strings? I guess I can serialize the list of strings in JSON format, but was hoping I could just transfer a List directly.

From Java Tutorial

For example, to create a data flavor for the java.util.ArrayList class:

   new DataFlavor(ArrayList.class, "ArrayList");
