how to create json array from java string for loop

Question

I have a JAVA for loop which prints the out put as shown below.

inside for loop::{"state":"tess","path":"/content/projectpath/en/men"} inside for loop::{"state":"hello","path":"/content/projectpath/en/women"}

Any my code snippet is as shown below.

for (Value val : values) {
                    //jsonobj = new JSONObject(val.getString());
                    out.println("inside for loop::" + val.getString());
                  // JSONArray jsonarr = val.getString();
               }// out.println("::"+jsonobj.toString());

How to get a JSON Array after the for loop which should have the values {"state":"tess","path":"/content/projectpath/en/men"} and {"state":"hello","path":"/content/projectpath/en/women"}

Your JSON data should be parsed as a JSONObject, not a JSONArray because it's object data, not an array. — Ted Hopp

@TedHopp its a multi valued string array, which i will get from the JCR, which is required to formulate as JSON ARRAY — krish

Okay. I reopened the question, as I thought it was about parsing. I see that @Kumaresan posted a workable solution. — Ted Hopp

create a JSONArray like this. insert your looping object on list. Finally you will get an array please try it.

JSONArray list = new JSONArray();
list.add(val);

it gives me the The method add(String) is undefined for the type JSONArray error with JSONArray list = new JSONArray(); list.add(val.getString()); code

JSONParser parser = new JSONParser(); String response = "{"state":"tess","path":"/content/projectpath/en/men"}"; JSONObject jsonObj = (JSONObject) parser.parse(response);

then add your object on list. refer thid link : stackoverflow.com/questions/5015844/parsing-json-object-in-java

Thank you, is there any possibility with import org.apache.sling.commons.json.JSONObject; import org.apache.sling.commons.json.JSONArray APIs for the same logic.

When you're using Apache Sling's version of JSONArray, instead of add(), the method is called put().
