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.
thanks.
