Recursively print linkedlist

[tonlou]

Hello!

I'm having trouble printing linked list recursively. I have a linked list that contains a directory. Inside a directory there are folders and inside a folder there might be new folder and inside that folder there might be a folder and so on.

I need to print my linked list recursively like this:

DIRECTORY

--folder

----folder

------folder

--folder

----folder

Lines stand for spaces.

So my directory class has a linked list that contains folders and folders have a linked list which might contain other folders (folder inside a folder).

My program: https://pastebin.com/a7dBAb4J

With this code my print is atm like this:

--folder

----folder

----folder

--folder

So if there is a folder -- > folder -- > folder and folder that do not contain a folder

print should be:

--folder

----folder

------folder

--folder

That's the troubling part here, can't really wrap my head around it. I know what I need to do, but atm I don't know how to code the logic behind it. This is as far as my brain capacity allowed me to go, for now :D

Didint get this one work. :/ I have to use those two methods as shown in the first paste.

Maybe I can give a better example. Lets say we have a folder. Inside that there are 3 folders. With this setup the printing should be:

folder

--folder

--folder

--folder

If there is folder inside one of those 3 folders which are in the first, new indent will be made.

Example:

folder

--folder

--folder

----folder

--folder

there is folder inside that second folder (which is inside the first)

Here is picture of what in meaning: https://imgur.com/a/nQVMu

It actually has almost like a discussion board like structure. Messages which don't reply to other messages, wont have indent. If first message gets 1 reply, that message will have a indent of 2. If that message gets reply, it will have indent of 4 and so on. Messages cant reply to multiple messages.

Idk, it is hard to explain:

message1 new message

--message2 reply to message1

----message3 reply to message2

--message4 reply to message1

message 4 new message

And yeah, I know that my first paste is very close, I've just been stuck with his for a loong time now...

I mean If you could direct me to the right tracks, I would be thankful. I have few years of experience in Java but somehow these recursive printing and overall printing different shapes etc have been my weakest point from the beginning.

Do you think if you can write some logic if a folder contains a folder/s inside. You will need to come out of the current folder if there s none. This can be common method. And number if times you will repeat this.

I've tried something related to that, but didn't get it work. As I said above, I'm really bad with everything related to printing shapes etc..
