The list of attributes to read is supplied in a string form using the following syntax:
view-name:comma-separated-attributes
The view-name is the name of the attribute view to read, such as basic, posix, acl, etc.
If view-name is omitted, it defaults to basic.
If view-name is present, it is followed by a colon.
You can read all attributes of a specific view type by specifying an asterisk.
For example, you can specify "basic:*" or "*" to read all basic file attributes.
To read the size and the last modified time of the basic view, you would use "basic:size,lastModifiedTime" or "size,lastModifiedTime".
To read the owner attribute of a file using an ACL view, you would use a string "acl:owner".
To read all posix attributes of a file, you would use "posix:*".
The following code prints the size and the last modified time of the file C:\myData\Main.java.
import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; import java.util.Map; public class Main { public static void main(String[] args) throws IOException { // Get a Path object Path path = Paths.get("C:\\myData\\Main.java"); // Prepare the attribute list String attribList = "basic:size,lastModifiedTime"; // Read the attributes Map<String, Object> attribs = Files.readAttributes(path, attribList); // Display the attributes on the standard output System.out.format("Size:%s, Last Modified Time:%s %n", attribs.get("size"), attribs.get("lastModifiedTime")); }/*from w w w .j ava 2 s .com*/ }
