如何从子文件夹中检索文件名

import os

def list_files_in_subfolders(directory):
    file_names = []
    for root, dirs, files in os.walk(directory):
        for file in files:
            file_names.append(os.path.join(root, file))
    return file_names

# 使用示例
directory_path = '/path/to/your/directory'
files = list_files_in_subfolders(directory_path)
for file in files:
    print(file)

const fs = require('fs');
const path = require('path');

function listFilesInSubfolders(dir) {
    let fileNames = [];
    const files = fs.readdirSync(dir);
    for (const file of files) {
        const filePath = path.join(dir, file);
        const stat = fs.statSync(filePath);
        if (stat.isDirectory()) {
            fileNames = fileNames.concat(listFilesInSubfolders(filePath));
        } else {
            fileNames.push(filePath);
        }
    }
    return fileNames;
}

// 使用示例
const directoryPath = '/path/to/your/directory';
const files = listFilesInSubfolders(directoryPath);
files.forEach(file => console.log(file));

import java.io.File;

public class ListFiles {
    public static void main(String[] args) {
        File directory = new File("/path/to/your/directory");
        listFiles(directory);
    }

    public static void listFiles(File directory) {
        File[] files = directory.listFiles();
        if (files != null) {
            for (File file : files) {
                if (file.isDirectory()) {
                    listFiles(file);
                } else {
                    System.out.println(file.getAbsolutePath());
                }
            }
        }
    }
}
