How to get the string array from JSONArray? 

  string [] D; Protected Zero ParseJsonString (ArrayList & lt; string []> DeptList, String Jason) {try {JSONArray array = new JSONArray (json); Int dl = array.length (); Println (dl); For (int i = 0; i & lt; array.label (); i ++) {d [i] = array.getString (i); } DeptList.add (d); For (string e: d) {System.out.println (e); }} Hold (JasonX Express E) {e.printStackTrace (); }}   
 I am debugging this code and I get an error here NullPointerException:  
  d [i] = array.getString (i );    
 
 
 you forgot  
  string [] d = New string [array.length];   
 then the string array D has not been started. And you try to use it on your first element  d [i]

I do not think this is a relativant code. Can anyone tell me what should I do?

Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.
