Rich'd suggestion is good and it ensures that the package exists.
However if you already know that the folder exists, this should do
the trick (and this should be faster):

IFolder folder = ...
IJavaElement element = JavaCore.create(folder);
if (element == null)
  return null;
if (element.getElementType == IJavaElement.PACKAGE_FRAGEMENT_ROOT)
  return ""; // default package
return element.getElementName();
