6. delete item in tree set    coderanch.com

ok, i know one is not supposed to subclass a java class unless it adds new and useful functionality, so forgive me, I am still learning.

7. Deleting node from binary search tree    coderanch.com

8. Question about deleting a node from a binary tree (non-API binary tree; hand-coded)    coderanch.com

Hi again, I've got something that's been bugging me. For this binary tree deleteNode function, when a node is found, the method deleteFromTree is called on it. I understand everything, except: this may sound silly, but it seems that the method passes the target node on in a roundabout way. As you see, when found == true, we don't simply pass ...

11. Is this an acceptable deletion method for a binary tree?    forums.oracle.com

I read elsewhere that the primary way to remove a node with one child is to take the pointer of the current node and point it instead to the current node's child, but we're not allowed a compareTo, remove() or findParent() method on the final exam. The whole thing has to be from scratch.

14. Binary Tree Deletion    forums.oracle.com

bug, For a start you need to break out of the static mentality. A Tree is-an object... and what does a Tree contain? Why TreeNode's of course. Also WTF is "root" doing in a tree node? Did you mean "item", or "value", or "data" or something like that? I think you did. The Tree has a "root" element (which is-a TreeNode) ...
