For example, we have a BufferedReader reader, associated with the json file through InputStreamReader . To get a file data we can do this:
A) var line: String? try { while (reader.readLine(). also { line = it } != null) { builder.append(line) } val json = JSONObject(builder.toString()) return json } catch (exception: IOException) { exception.printStackTrace() } catch (exception: JSONException) { } while (reader.readLine(). also { line = it } != null) {
B) var line: JSONObject ? while (reader.readJSONObject (). also { line = it } != null) { while (reader.readJSONObject ().
C) } catch (exception: RuntimeException) { } catch (exception: ArrayIndexOutOfBoundsException) {

The code snippet uses the `BufferedReader` class to read a JSON file line by line and append it to a `StringBuilder`.The `readLine()` method returns a `String?`, which is assigned to the `line` variable using the `also` function.The `while` loop continues until the `readLine()` method returns `null`, indicating that the end of the file has been reached.The `JSONObject` constructor is then used to parse the JSON string into a `JSONObject` object.
