java - How to get data from dynamically generated JavaFX PieChart? -


i'm trying figure out how , update existing data in set of dynamically created pie charts in javafx. these pie charts saved in arraylist. first task figure out how data.

as i'm creating these pie charts dynamically set of fluid data sources, cannot make multiple observable lists using code similar this:

private observablelist<piechart.data> datalist = fxcollections.observablearraylist();

any ideas on how can read data name , value each dynamically generated pie chart slice?

every piechart (view) has access own observablelist<piechart.data> (model) via data property. given list<piechart> named list, can traverse list , examine or update each chart's data warranted:

list.get(0).getdata().get(0).setpievalue(42); (piechart p : list) {     (piechart.data data : p.getdata()) {         system.out.println(data);     } }

console (data ensemble8 piechartapp):

data[sun,42.0] data[ibm,12.0] data[hp,25.0] data[dell,22.0] data[apple,30.0]

as alternative having list of views, list<piechart>, consider maintaining list of models, list<observablelist<piechart.data>>.

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
