How do I check if a file is hidden?

The File.isHidded() method checks to see if the file represented by aFile object is a hidden file. The definition of hidden is vary between operating systems. On UNIX based systems, a file is considered to be hidden when their name begins with a period character ('.'). On Windows operating system, a file is considered to be hidden if it has been marked hidden in the filesystem.

This File.isHidden() method returns true if and only if the file denoted by this File object is hidden according to the conventions of the underlying platform.

package org.kodejava.example.io;

import java.io.File;
import java.io.IOException;

public class FileHiddenExample {
    public static void main(String[] args) throws IOException {
        File file = new File("Hidden.txt");
        file.createNewFile();

        // We are using the isHidden() method to check whether a file
        // is hidden.
        if (file.isHidden()) {
            System.out.println("File is hidden!");
        } else {
            System.out.println("File is not hidden!");
        }
    }
}
