Java File isDirectory, isFile both return false

Type: Tertiary directory A (Dir) – B (Dir) – C (File)

①File child = new File(children[i]);

File child = new File(dir, children[I]); File child = new File(dir, children[I]);

Passing in the parent directory correctly identifies the child’s type.

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

Demo: Deletes only files, not folders

public boolean deleteDir(File dir) {
    if (dir == null) {
        return false;
    }
    if (dir.isDirectory()) {
        String[] children = dir.list();
        int len = children.length;
        if (len == 0) {
            return true;
        }
        for (int i = 0; i < len; i++) {
            File child = new File(dir, children[i]);
            boolean success;
            if (child.isDirectory()) {
                if (child.list().length == 0) {
                    return true;
                }
                success = deleteDir(child);
            } else {
                success = child.delete();
            }
            if(! success) {return false;
            }
            if (i == len - 1) {
                return true; }}}return dir.isDirectory();
}
