FileUtils.setPermissions

FileUtils.setPermissions is a method provided by the Apache Commons IO library in Java. It is used to set the permissions of a file or directory. This method allows you to specify the permissions as an integer value.

Here is an example of how to use FileUtils.setPermissions:

import org.apache.commons.io.FileUtils;
import java.io.File;
import java.io.IOException;

public class Main {
    public static void main(String[] args) {
        File file = new File("path/to/file");
        
        try {
            // Set permissions to 644 (read and write for owner, read-only for others)
            FileUtils.setPermissions(file, 0644);
            System.out.println("Permissions set successfully.");
        } catch (IOException e) {
            System.out.println("Error setting permissions: " + e.getMessage());
        }
    }
}

In this example, we create a File object representing the file whose permissions we want to set. We then call FileUtils.setPermissions and pass the file object and the desired permissions as an octal value (0644 in this case). If the permissions are successfully set, it will print "Permissions set successfully." Otherwise, it will print an error message.
