How to Get Arrays Separately from JSON Objects in Rest

Question

Lately i have been trying to consume a Rest service which returns the below rough sample JSON. It has objects which contains Arrays and arrays contains Strings.

    {
   Main Object:{

      Object1:{
           }
      Object2:{
           }
      Object3:{
               Array1[String1,String2,String3]
               Array2[String1,String2,String3]
               Array3[String1,String2,String3]
               Array4[String1,String2,String3]
               }

    }}

My requirement is to get all the arrays and check which of the specific array contains specific/required String values and than get those strings to show in jsp.

I am using Spring MVC(Rest Template) but any java based solution would do the work.

P.S: I am New to WebServices.

The number of objects (Object1, Object2) is fixed ? or it may change between calls ? — reos

use JSONArray to get it from below

JSONArray jsonArray = new JSONArray();

jsonArray = JSONObject.getJSONObject("Main Object").getJSONObject("Object3").getJSONArray("Array1");

//Iterate through the above array to get required String.

for the next array :

jsonArray = JSONObject.getJSONObject("Main Object").getJSONObject("Object3").getJSONArray("Array2");
