How do I get file basic attributes?

This example you’ll learn how to get file’s basic attributes. Basic file attributes are attributes that are common to many file systems and consist of mandatory and optional file attributes as defined by the BasicFileAttributes interface.

The file’s basic attributes include file’s date time information such as the creation time, last access time, last modified time. You can also check whether the file is a directory, a regular file, a symbolic link or something else. You can also get the size of the file.

Let’s see the code snippet below:


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

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

        Path file = Paths.get(path);
        BasicFileAttributes attr = Files.readAttributes(file, BasicFileAttributes.class);
        System.out.println("creationTime     = " + attr.creationTime());
        System.out.println("lastAccessTime   = " + attr.lastAccessTime());
        System.out.println("lastModifiedTime = " + attr.lastModifiedTime());

        System.out.println("isDirectory      = " + attr.isDirectory());
        System.out.println("isOther          = " + attr.isOther());
        System.out.println("isRegularFile    = " + attr.isRegularFile());
        System.out.println("isSymbolicLink   = " + attr.isSymbolicLink());
        System.out.println("size             = " + attr.size());

The output of the code snippet:

creationTime     = 2021-05-05T17:09:09.0628061Z
lastAccessTime   = 2021-05-05T17:09:09.0628061Z
lastModifiedTime = 2021-11-04T00:11:43.279Z
isDirectory      = false
isOther          = false
isRegularFile    = true
isSymbolicLink   = false
size             = 0
