java中怎么获取文件夹属性

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：

1. 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.");         }     } } 

2. 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。
