Hidden files are files that exist on a computer but are not visible when you list or examine the computer. Hidden files are basically used to hide information.
If a file’s name begins with a period character (.), the file is considered hidden in UNIX. If a file isn’t a directory and the DOS hidden property is set, it is deemed hidden in Windows.
Files.isHidden() methodThe isHidden() method is a static method in the Files class that checks whether the given file path is a hidden file or not.
The Files class is in the java.nio.file package.
public static boolean isHidden(Path path)
This method takes one parameter, Path path, which is the file path.
This method returns true if the file is hidden. Otherwise, it returns false.
In the code below, we create a Path object from the file path, which is passed as argument to the isHidden() method.
If the file is hidden, the program prints File is Hidden.
If the file is not hidden, the program prints File is not Hidden.
import java.io.IOException;import java.nio.file.Files;import java.nio.file.Path;import java.nio.file.Paths;public class Main {public static void main(String[] args) throws IOException {Path filePath = Paths.get("hiddenFile.txt");boolean isHidden = Files.isHidden(filePath);System.out.println(isHidden? "File is Hidden": "File is not Hidden");}}
