We can check a file is hidden or not in Java using isHidden() method of File class in Java. This method returns a boolean value – true or false.
public static boolean isHidden(Path path) throws IOException parameters: path – the path to the file to test. throws: IOException – if an I/O error occurs SecurityException – In the case of the default provider, and a security manager is installed, the checkRead method is invoked to check read access to the file. returns: true: if file is hidden false: if file is not hidden
The precise definition of hidden is platform or provider dependent.
UNIX: A file is hidden if its name begins with a period character (‘.’).
Windows: A file is hidden if it is not a directory and the DOS hidden attribute is set.
