Answer 1

public static void main(String[] args){
JSONObject data = new JSONObject();
JSONObject result = new JSONObject();
JSONObject json1 = new JSONObject();
JSONObject json2 = new JSONObject();
//{"result": {"status": {"msg": "","code": 0 },"count": {"qreply": 300,"total": 344,"show": 33 } }}
json1.put("code", 0);
json1.put("msg", "");
json2.put("qreply", 300);
json2.put("total", 344);
json2.put("show", 33);
result.put("status", json1);
result.put("count", json2);
data.put("result", result);
JSONObject obj = (JSONObject) data.get("result");
JSONObject obj2 = (JSONObject) obj.get("count");
int a = (Integer) obj2.get("total");
System.out.println(a);
}

根据你json里放不同的类型，取值时不一样的。我都是用json给你取值了

data[1].tocal

data.result.count.total
