How to remove braces [] from JSON Array data output?

Question

My JSON structure is simple :

 "categories": [2],

I am succesfull in getting this output on my Android studio code as :

  JSONArray jsonArray = jsonObject.getJSONArray("categories");
  Log.e("CAT ID", String.valueOf(jsonArray));

Output is :

E/CAT ID: [2]  //and other IDS respectively

My question is how can I remove the braces and just get the Integer values?

You can call get() to get array value.

//If array contains only one value use get(0)

    JSONArray jsonArray = jsonObject.getJSONArray("categories");
    
    jsonArray.get(0);

//If Array contains more value use for() loop

for(int i=0;i<jsonArray.length;i++){
      jsonArray.get(i);

}

jsut use below code :

String.valueOf(jsonArray)
    .replace("[","")
    .replace("]","")

or

jsonArray.toString()
    .replace("[","")
    .replace("]","")
