how can you get a content of a folder with a stream in java?

Question

I'm trying to create my own stream, something like a PathContentStream, that gets a path and returns how many files, folders, and sub-folders are in it and what type they are (like avi or txt).

Is there anything in the java streams API that would be useful to implement this?

Answer 1

It is not quite clear what will be an essense of such stream. General answer: no, there is not such streams in java api. But if you will compose the essense of it, you can create your own, which will implement something like:

public interface InputFileItemStream implements Closeable {

     File read();
     void close();
     void reset();
     ...
}
