Listing subfolders with Java api v2

[SparkyNZ]

I am using code such as the snippet below to retrieve file details from Dropbox. How can I tell which entries are folders?

I thought there would have been a member in FileMetadata but I am just not seeing it.

ListFolderResult result = mDbxClient.files().listFolder("" );

while( true )
{
  for( Metadata metadata : result.getEntries() )
  {
    String           sName        = metadata.getPathLower();
    FileMetadata     fileMetadata = (FileMetadata) metadata;

OK, I found the answer here:

The short answer is that I need to test metadata with instanceof to see if it is an instance of FolderMetaData or FileMetaData. Java isn't my primary programming language so that was the last thing I would have thought of doing.
