possible code optimizations while using JSONObject

I have following JSONArray object from a jsonobject key "elements"

[ {
    "id":"as-a-user,-i-should-be-able-to-navigate",
      "elements":[  

    {
        "id": "navigate-down",    
        "type":"scenario"
    }
    ,
    {
        "id": "navigate-up",
        "type":"scenario"
    }
    ,
    {
        "id": ";eating",
        "examples":[ {
            "id": "as-a-user,-i-should-be-able-to-navigate;eating;", "description":"", "name":"", "keyword":"Examples", "line":23, "rows":[ {
                "id": "eating;;1", "cells": ["start", "eat", "left"], "line": 24
            }
            ,
            {
                "id": "eating;;2", "cells": ["12", "5", "7"], "line": 25
            }
            ,
            {
                "id": "eating;;3", "cells": ["20", "5", "15"], "line": 26
            }
            ]
        }
        ],
        "type":"scenario_outline"
    }
    ]
}

]

Here is the code i used to find the "rows" key details in the above JSON array.Am getting the row key values using the below code.My code using lots of JSONObjects and JSONArrays to get data.I have to do some code optimizations .How can i simplyfy my code.any better solutions?

code

JSONObject jsonObject = convertFileToJSON();
            JSONArray elementsArray= (JSONArray) jsonObject.get("elements");        
            for(int i = 0; i < elementsArray.size(); i++)
            {
                  JSONObject objects = (JSONObject) elementsArray.get(i);                
                  if(objects.get("keyword").equals("scenario_outline")){
                      JSONArray elementsArray1= (JSONArray) objects.get("examples"); 
                      JSONObject objects1 = (JSONObject) elementsArray1.get(0);                 
                      JSONArray rowArray= (JSONArray) objects1.get("rows");
                      System.out.println(rowArray.size());

                  }

            }
