Answer Posted / Sumit Kumar Yadav
To list all files in a directory using Java's File class, you can use a recursive approach. Here's an implementation:n```npublic static void listFiles(File dir) {n if (dir.isDirectory()) {n File[] children = dir.listFiles();n for (File file : children) {n if (file.isDirectory()) {n System.out.println("Directory: " + file.getName());n listFiles(file);n } else {n System.out.println("File: " + file.getName());n }n }n }n}n```
