Json parsing issue(values auto changed float)

Hi i have mention my json format below

[{
    "id": "1",
    "MinValue": 2,
    "MaxValue": 29
}, {
    "id": "2",
    "MinValue": 0.5,
    "MaxValue": 5.6
}]

While i am parsing the MinValue & MaxValue its return like 2.0,29.0(float) Kindly help me to get exact value.

My parsing code

JSONArray jsonArray = new JSONArray(result);

if (jsonArray != null) {
    for (int i = 0; i < jsonArray.length(); i++) {
        try {
            JSONObject profileObject = jsonArray.getJSONObject(i);
            String minValue = profileObject.getString(Constants.VALUE_BMCPROFILE_MINVALUE);
            String maxValue = profileObject.getString(Constants.VALUE_BMCPROFILE_MAXVALUE);
        }
    }
}

If you are really getting trouble then the alternate solution is remove .0 like this

   if(MinValue.endsWith(".0")){
         String myMinValue = MinValue.substring(0,MinValue.indexOf('.'))        
    }

Something like this should work

JSONArray jsonArray = new JSONArray(result);

if (jsonArray != null) {
    for (int i = 0; i < jsonArray.length(); i++) {
        try {
            JSONObject profileObject = jsonArray.getJSONObject(i);

            Object minValue = profileObject.get(Constants.VALUE_BMCPROFILE_MINVALUE);
            if (minValue instanceof Integer) {
                int min = (int) minValue;
            } else if (minValue instanceof Double) {
                double min = (double) minValue;
            }

            Object maxValue = profileObject.get(Constants.VALUE_BMCPROFILE_MAXVALUE);
            if (maxValue instanceof Integer) {
                int max = (int) maxValue;
            } else if (maxValue instanceof Double) {
                double max = (double) maxValue;
            }
        } catch (Exception e) {

        }
    }
}

Then proceed with the int or double to do what you want

You can get the double value from JSON then remove .0 if needed

DecimalFormat decimalFormat=new DecimalFormat("#.#");
double minValue = decimalFormat.format(profileObject.getDouble(Constants.VALUE_BMCPROFILE_MINVALUE));
double maxValue = decimalFormat.format(profileObject.getDouble(Constants.VALUE_BMCPROFILE_MAXVALUE));

Replace this with 

String minValue = profileObject.getString(Constants.VALUE_BMCPROFILE_MINVALUE);
String maxValue = profileObject.getString(Constants.VALUE_BMCPROFILE_MAXVALUE);

this

double minValue = profileObject.getDouble(Constants.VALUE_BMCPROFILE_MINVALUE, 0);
double maxValue = profileObject.getDouble(Constants.VALUE_BMCPROFILE_MAXVALUE, 0);

as per json data min and max values are clearly Double not String.
