在Java中获取文件夹的属性可以通过使用File类或者Files类来实现。以下是两种方法的示例：

使用File类：

import java.io.File;public class GetFolderProperties {public static void main(String[] args) {File folder = new File("path/to/folder");if (folder.isDirectory()) {System.out.println("Folder name: " + folder.getName());System.out.println("Folder path: " + folder.getAbsolutePath());System.out.println("Folder size: " + folder.length());System.out.println("Last modified: " + folder.lastModified());} else {System.out.println("Not a valid folder path.");}}}

使用Files类：

import java.nio.file.Files;import java.nio.file.Path;import java.nio.file.Paths;import java.io.IOException;public class GetFolderProperties {public static void main(String[] args) {Path folderPath = Paths.get("path/to/folder");try {System.out.println("Folder name: " + folderPath.getFileName());System.out.println("Folder path: " + folderPath.toAbsolutePath());System.out.println("Folder size: " + Files.size(folderPath));System.out.println("Last modified: " + Files.getLastModifiedTime(folderPath));} catch (IOException e) {System.out.println("Error accessing folder properties: " + e.getMessage());}}}

请注意，以上示例中的path/to/folder需要替换为实际文件夹的路径。这些示例将打印出文件夹的名称、绝对路径、大小和最后修改时间等属性。
