Re: Saving BinaryTree to file. 14 Years Ago by JainishP [QUOTE=Salem;1184865]You seem to be opening and closing the file at every node.[/QUOTE] How so? So far I haven't written code to close the file that I'm saving to. Is it because this is in "try"?: [CODE]bufferedWriter = new BufferedWriter(new FileWriter("savedtree.txt"));[/CODE] Re: Saving BinaryTree to file. 14 Years Ago by Salem It's because you do that for EVERY node. Your function should be [code] void filePreOrder(BufferedWriter bufferedWriter) [/code] so that you have just ONE file instance you pass through the tree, writing to as you go. The caller is responsible for creating the file in the first place, then closing the file when you're done.
