Android JSONArray去重

记录一个方法。

如果有这样的一段数据：

   [{
            "riskCode":"200731",
            "riskName":"信泰如意尊（典藏版）终身寿险",
            "payIntv":"IRREGULAR",
            "years":"",
            "prem":"",
            "payYears":""
        },
        {
            "riskCode":"200731",
            "riskName":"信泰如意尊（典藏版）终身寿险",
            "payIntv":"IRREGULAR",
            "years":"",
            "prem":"",
            "payYears":""
        }
    ]

希望去重，得到一条数据，方法：

    private static JSONArray delRepeatIndexid(JSONArray array) {
        JSONArray arrayTemp = new JSONArray();
        int num = 0;
        try {
            for (int i = 0; i < array.length(); i++) {
                if (num == 0) {
                    arrayTemp.put(array.get(i));
                } else {
                    int numJ = 0;
                    for (int j = 0; j < arrayTemp.length(); j++) {
                        JSONObject newJsonObjectI = (JSONObject) array.get(i);
                        JSONObject newJsonObjectJ = (JSONObject) arrayTemp.get(j);
                        String index_idI = newJsonObjectI.get("riskCode").toString();
                        String valueI = newJsonObjectI.get("riskName").toString();
                        String payIntvI = newJsonObjectI.get("payIntv").toString();
                        String yearsI = newJsonObjectI.get("years").toString();
                        String premI = newJsonObjectI.get("prem").toString();
                        String payYearsI = newJsonObjectI.get("payYears").toString();
                        String index_idJ = newJsonObjectJ.get("riskCode").toString();
                        if (index_idI.equals(index_idJ)) {
                            arrayTemp.remove(j);
                            JSONObject newObject = new JSONObject();
                            newObject.put("riskCode", index_idI);
                            newObject.put("riskName", valueI);
                            newObject.put("payIntv", payIntvI);
                            newObject.put("years", yearsI);
                            newObject.put("prem", premI);
                            newObject.put("payYears", payYearsI);
                            arrayTemp.put(newObject);
                            break;
                        }
                        numJ++;
                    }
                    if (numJ - 1 == arrayTemp.length() - 1) {
                        arrayTemp.put(array.get(i));
                    }
                }
                num++;
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return arrayTemp;
    }
