Can any one help me where it got saved and what is issue with the below code

class ByteArrayRequest (
    method: Int,
    url: String,
    context: Context,
    jsonRequest: JSONObject?,
    listener: Response.Listener<ByteArray>,

            val fileOutputStream = FileOutputStream(file)
            fileOutputStream.write(response.data)
            fileOutputStream.close()

            Response.success(
                response.data,
