如何遍历JsonArray在Java [英] How to iterate JsonArray in java

问题描述

我想从JsonArray提取值。 Jsonarray具有行和列的n个。

I would like to extract the values from JsonArray. Jsonarray has n number of rows and columns.

ObjectMapper mapper = new ObjectMapper();
        DynamicForm dynamicForm = new DynamicForm();
        dynamicForm = dynamicForm.bindFromRequest();
        Dynamic dynamic = dynamicForm.get(); 
        //List<OneModel> list = new ArrayList<OneModel>();
        //List iterate=new ArrayList();

        String data = dynamic.getData().get("content").toString();
        try {
            JSONArray jsonArray = new JSONArray(data);
            for (int i = 0; i < jsonArray.length(); i++) {
                System.out.println(jsonArray.get(i));
        } }catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   

其结果如下：

["1001432","05-KALENJI-P1229","KALENJI","2","2014-11-09 09:37:14.379482",""],
["1001432","05-KALENJI-P1228","KALENJI","1","2014-11-09 09:37:14.379482",""],
["1001432","05-KALENJI-P1227","KALENJI","5","2014-11-09 09:37:14.379482",""]

我想提取一个接一个的值，并将其分配给变量。例如1001432,05-KALENJI-P1229，KALENJI，2,2014-11-09 09：37：14.379482。这样我可以处理每个值。请任何一个帮助我在同一个

I would like to extract one by one values and assign it to variable. for example 1001432,05-KALENJI-P1229,KALENJI,2,2014-11-09 09:37:14.379482. So that i can process each values. Please any one help me in the same

推荐答案

您使用此code可以做的，

you can done using this code,

这是一个完美的code，

This is the perfect code,

//把数据串的JSON

//put your json in data string

JSONArray jsonArray=new JSONArray(data);
            if(jsonArray!=null && jsonArray.length()>0){
                for (int i = 0; i < jsonArray.length(); i++) {
                    JSONArray childJsonArray=jsonArray.optJSONArray(i);
                    if(childJsonArray!=null && childJsonArray.length()>0){
                        for (int j = 0; j < childJsonArray.length(); j++) {
                            System.out.println(childJsonArray.optString(j));
                        }
                    }
                }
            }
