This code snippet show you an example on how to set the value of file attributes. Here we will set the DosFileAttributes. To set the value of file attributes we use the Files.setAttributes() method. To set DosFileAttributes we can use the following attributes: "dos:archive", "dos:hidden", "dos:readonly" and "dos:system".

For details let’s see the code snippet below:

package org.kodejava.io;

import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.attribute.DosFileAttributes;

public class UpdateDosFileAttributesExample {
    public static void main(String[] args) throws Exception {
        String path = "D:/resources/data.txt";
        Path file = Paths.get(path);

        // Get current Dos file attributes and print it.
        DosFileAttributes attr = Files.readAttributes(file, DosFileAttributes.class);
        printAttributes(attr);

        // Set a new file attributes.
        Files.setAttribute(file, "dos:archive", false);
        Files.setAttribute(file, "dos:hidden", false);
        Files.setAttribute(file, "dos:readonly", false);
        Files.setAttribute(file, "dos:system", false);

        // Read the newly set file attributes and print it.
        attr = Files.readAttributes(file, DosFileAttributes.class);
        printAttributes(attr);
    }

    /**
     * Print the DosFileAttributes information.
     *
     * @param attr DosFileAttributes.
     */
    private static void printAttributes(DosFileAttributes attr) {
        System.out.println("isArchive()  = " + attr.isArchive());
        System.out.println("isHidden()   = " + attr.isHidden());
        System.out.println("isReadOnly() = " + attr.isReadOnly());
        System.out.println("isSystem()   = " + attr.isSystem());
        System.out.println("----------------------------------------");
    }
}

The output of the code snippet:

isArchive()  = true
isHidden()   = true
isReadOnly() = true
isSystem()   = true
----------------------------------------
isArchive()  = false
isHidden()   = false
isReadOnly() = false
isSystem()   = false
----------------------------------------
