Get supported file formats

GroupDocs.Annotation allows to get the list of all supported file formats by following the below steps:

• Call getSupportedFileTypes() method of FileType class;
• Enumerate through the collection of FileType objects.

The following code sample demonstrates how to get supported file formats list.

		List<FileType> fileTypes = FileType.getSupportedFileTypes();
        //foreach to while statements conversion
        Iterator items = (fileTypes).iterator();
        while (items.hasNext()) {
            FileType fileType = (FileType) items.next();
            System.out.println(fileType.getExtension());
        }
