Reset to default
1 
JSONArray jsonArray = new JSONArray(mainJSON.getJSONArray("participants"))

Then you just use your object like this:

 jsonArray.getJSONObject(0)

if there is two values inside participants like [abc, xyz] then how to parse and save in arraylist
Value Socrates at 0 of type java.lang.String cannot be converted to JSONObject
Switch participants.getString(i) to participants.getJSONObject(i)
If the contents of your participants array are strings, you use getString(i), and getJSONObject(i) if they're objects. Your compiler is telling you that they're strings but you're trying to access them as JSON objects.
Attempt to invoke interface method 'boolean java.util.List.add(java.lang.Object)' on a null object reference.. I am using List<String> to save the data inside participants and i am getting this error.
