Hi, I want to read data from some table and maintain it in a data structure. Table o/p is like:
Id Parent Id -- --------- 1 0 2 0 3 2 4 3 5 2 6 0 7 6 8 6 Here parent id 0 means that node is a parent node. I want to know the way that I can use to maintain this data in a data structure(HashMap,ArrayList etc.) so that I can read it in my jsp. As an example data structure should say: for Id number 6 -> 7 and 8 are the children.
