JADE Multi-agent adding elements into JSON Array

Question

I am having a problem with adding elements to JSON array iteratively using JADE Multi agent platform.
For example, the original JSON array was {["a","b","c]}. I want my result to be {["a","b","c","1","2"]}.
The JSOn Array element adding should be placed inside a cyclic behaviour.
I got something like this.

i=1
JSONArray array = new JSONArray();
JSONObject jsonObj = new JSONObject();
jsonObj.put("char",array);

addBehaviour(new TickerBehaviour(this,3000) {
array.add( i);
i++;
}

But the result was:

{["a","b","c","1"]}
{["a","b","c","2"]}

Where are you adding a, b, c to the array? Also, char should be in the output. Please show a [mcve] — OneCricketeer, May 05 '18 at 15:16

If I understand correctly, you need to overwrite the previous object value with the updated one

array.add(i++);
jsonObj.put("char",array);

Hi. I actually want to add the new value to the array not overwrite. The desired result should be:{["a","b","c","1"]} then {["a","b","c","1","2"]} – Anonymous May 05 '18 at 15:26
This does add a value to the array... It overwrites the array previously in the outer object – OneCricketeer May 05 '18 at 15:27
You should get `{"char":[1]}` then `{"char":[1, 2]}` with the code posted and this solution – OneCricketeer May 05 '18 at 15:28
