Array new jsonarray param.tostring

A Java question!

param.toString() will convert the param object to a string representation. If you want to create a JSON array from this string, you can use the JSONArray class from the org.json package.

Here's an example:

import org.json.JSONArray;
import org.json.JSONObject;

// assume param is an object that has a toString() method
String jsonString = param.toString();
JSONArray jsonArray = new JSONArray(jsonString);

In this example, param.toString() will convert the param object to a string, and then JSONArray will parse this string into a JSON array.

Alternatively, if you have a JSONObject instead of a string, you can use the getJSONArray() method to create a JSON array:

JSONObject jsonObject = new JSONObject();
JSONArray jsonArray = jsonObject.getJSONArray("key"); // assuming "key" is the key of the JSON array

Note that if param is not a string, you may need to convert it to a string using String.valueOf() or another method before passing it to JSONArray.
