Finding File Type

[vikisri12345]

hello,
i have a file named "sxase" in my home directory.on checking the properties i find that the file type is ".mp4".i am looking for a java code that can tell me the extension for the file name "sxase".As i am working on the project that involves implementation of this code too i dont want any tools such as "TRID" etc
THANKS IN ADVANCE

String ext = FilenameUtils.getExtension("/path/to/file/foo.txt");

Thanks for your reply. in my case absolute file name is "foo" and not "foo.txt" . So how to find its a Text File type now?

That's windows hiding the full file name - there's an option in Folder Properties to not hide known extensions.
