Btree 21 Years Ago by CodeMasterFlex I'm trying to write a Btree remove method in JAVA I'm having trouble combining my nodes and then recursing up through the parent does anyone know where I can get some info about this online? Re: Btree 21 Years Ago by CodeMasterFlex I figured it out and now know more about Btree than I ever thought possible Re: Btree 18 Years Ago by JTMoney … searching the web for some examples of creating a java btree... but for my class assignment she wants it without parent… Re: Btree 18 Years Ago by CodeMasterFlex … searching the web for some examples of creating a java btree... but for my class assignment she wants it without parent… Re: Btree 17 Years Ago by parvin1987 hello all I'm searching for a sample code to creat a BTree but every code I find,is importing a package(that is not belong to standard java).can any one give me a link for a source code that doesn't use their own package? thanks and regards parvin Re: Btree 17 Years Ago by parvin1987 thank you jwenting for being suspicious about me.my jbuilder didn't let me use not standard libs so I had to find a BTree implementation without using packages. anyway,my problem was solved thanks btree traversal algorithm 13 Years Ago by montjoile …, I have the structure and the insertion method of a btree, but I need to do the traversal method.

Re: Btree 18 Years Ago by JTMoney im still having trouble figuring out this remove and merge methods... if at all possible, could i send my code to you and you can see what im working with??? Re: Btree 17 Years Ago by jwenting do your own homework kiddo. and don't go around reviving long dead threads. Re: Btree 17 Years Ago by parvin1987 It's not my homework jwnting .it's for my work. I need help Re: Btree 17 Years Ago by jwenting it's not. If it were you would a) happily use a third party library because it saves you work and b) not bother writing your own version of something that's already in the standard library. Only homework assignments have both the requirement to not use external libraries and to build from scratch something that's available in the core API. Re: Btree 17 Years Ago by jwenting JBuilder will let you use whatever you want if you know how to use JBuilder... The fact that you don't confirms yet again your status in society as someone who doesn't do this for a living (and most likely uses a pirated copy of JBuilder that doesn't include the documentation).

Re: What are the differences between an AVL tree and a Btree 15 Years Ago by bamcclur Well, Btrees can have more than two paths spanning from each node, so I think you could generally use your AVL tree, and do some modifications to it. Why not do some reading on how to balance your Btree [URL="http://en.wikipedia.org/wiki/Btree"]http://en.wikipedia.org/wiki/Btree[/URL] Re: What are the differences between an AVL tree and a Btree 15 Years Ago by UberJoker I have already read that...my question was can somebody point out the exact differences between the two and where the modifications need to be done in an AVL tree to make it a Btree.

Basically it goes along the lines of passing the root node to the function. The function itself goes something like this (for infix): IF left child exists THEN PASS left child to the function PRINT value of current node IF right child exists THEN PASS right child to the … Re: What are the differences between an AVL tree and a Btree 15 Years Ago by Nick Evan [URL="http://eternallyconfuzzled.com/tuts/datastructures/jsw_tut_avl.aspx"]Read this[/URL] Re: What are the differences between an AVL tree and a Btree 15 Years Ago by Narue [B]>You didn't click the link I gave you right?
