Traversing directories without using recursion?

Question

The Problem I need to write a simple software that, giving certain constraints, appends to a list a series of files. The user could choose between

Answer 1

If you choose to use recursion, I found an example that may be close to the one you are currently using as to eliminate any ambiguity .

// Process only directories under dir
public static void visitAllDirs(File dir) {
    if (dir.isDirectory()) {
        process(dir);

        String[] children = dir.list();
        for (int i=0; i

This is a very simple example, the process() can be where you do your handling or operations on the directory.
