Simply use Jackson JSON Parser (https://github.com/FasterXML/jackson)

String jsonString = "[{\"n\":0},{\"n\":1}]"; // add your JSON here
ObjectMapper mapper = new ObjectMapper();
JsonNode actualObj = mapper.readTree(jsonString);
Iterator<JsonNode> it = actualObj.iterator();
while(it.hasNext()) {
  JsonNode next = it.next();
  System.out.println(next.get("n"));
}
