I am having 2 problems: 1. I am using EasyWriter to write to the .txt, but i must use (String, "app) or ... |
if a node is null, "_" represents the empty sub-tree. EXAMPLE: "[ _ , 1 , [ [ _ , 3 , _ ] , 2 , _ ] ]" is the description of a tree with 3 nodes. The root with label 1 as only 1 son, the right one. That node has label 2 and only 1 son at ... |
Hi, I need to have an implementation of an AND-OR tree, that is, a tree in which the children of a node can either be conjunctive or disjunctive (normally the parent is consider an AND-node or an OR-node). The reason is that I need to represent Prolog rules in a java structure (not simply as a string). Do you know of ... |

13. Trees forums.oracle.comWhat do you want to implement about JTree? It is already done in hte JDK and pretty well for general purposes. To listen to mouse events implement a mouse listener (java.awt.event.MouseListener) and register it with the JTree. And probably you will want to show a JPopupMenu when an aven is fired. Mike |

I assumed name and contact were related. Two lists would make sense too (as long as you don't need to match name to a contact). Or (just to belabor the point), why not use a Map that contains Lists for values? Map map = new HashMap(); map.put("Name", new ArrayList("John", "David")); map.put("Contact", new ArrayList("Country", "State")); Again, none of this really addresses the ... |
16. (2,4) tree forums.oracle.comI have an assignment to create a 2,4 tree. I understand how the tree works and could do it on paper but am having a tough time creating the actual methods. I'm stuck on the insert method, the book states to search for the key and if you find a leaf return insert it in the parent. If the node is ... |
