Posted 04 April 2013 - 11:48 PM

hey first time using this anyways i have the skeleton of this whole included below and i was hoping someone could help walk me through the steps on how to get this started and help me with any difficulties i come across the way. I've included the all the files i have for it in the attachment any and all help is appreciated. thank you hope to here back soon

Welcome to DIC. Since your due date is near, you may not get the help you need in time, but here are some pointers for a more successful visit in the near future. These same hints are probably included in the forum's FAQ, so the first hint is to . . .:

1. . . . Read the forum's FAQ. It's in an "Announcement" sticky at the top of the forum's first page, titled, "New to Dream.In.Code - FAQ"

2. Don't wait until the last minute and request "urgent" help. Many yawn and move on. I'd go so far as to suggest that NOT mentioning due dates at all will get faster responses.

3. Most here are wary of attachments (or too lazy to bother with them), so copy/paste the relevant portions of the assignment directly into the topic, in code or quote tags if it simplifies reading and improves the appearance.

4. Ask specific questions, post errors, describe your efforts to overcome obstacles, and show evidence of the effort expended (sweat on the post, if possible). General requests for hand holding, "support" (whatever that is), beta testing, walking through, explaining, compliance assessment, etc. are not responded to as eagerly.

5. On a slow day, every post, no matter how inane or lousy, gets an answer. May your urgent requests all occur on slow days. (Just don't say so.)

Good luck, and keep coding!

ok so what kind of data structure should i use to store the information i was thinking its supposed to be a binary tree implemented by a linked list but than in my imports i have this import net.datastructures.LinkTree; and this import net.datastructures.BinaryTree; which makes me think i should be just using a linktree type thing, but when i create a new object with those types it seems like its just calling the methods that are in my class I'm trying to finish, and in that since pointless
