Question

我有一个文件夹结构，如：E：\ Test。在其中，我有很多子文件夹，例如FolderA，FolderB，FolderC等。

我想要一个Java程序，该程序将列出所有子文件夹和子文件夹中的报告文件。我该如何实现？使用下面的代码片段，我可以访问E：\ Test目录中的其他文件夹，但是子文件夹中的文件没有出现。

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;

public class Main {

    private static final StringBuilder tabs = new StringBuilder();

    public static void main(String[] args) {
