Convert JSON data to array form

Convert JSON data to array form

var data = [{

"a": "1",

"b": "2",

"c": "3 4 5 6 7"

}];

for(var i = 0; i

var obj = data[i];

for(var k in obj){

var arr = obj[k].split(/\s /);

if(arr.length > 1){

for(var j = 0; j

obj[k "_" (j 1)] = arr[j];

}

delete(obj[k]);

}

}

}

console.log(data);

java解析json数据成数组

import net.sf.json.JSONArray;

public class TestJson

{

public static void main(String []args)

{

String json = "[{\"a\":\"111\",\"b\":\"222\",\"c\":\"333\"},{\"a\":\"1000\",\"b\":\"2000\",\"c\":\"000\"},{\"a\":\"999\",\"b\":\"300\",\"c\":\"700\"}]";

JSONArray jsonArr = JSONArray.fromObject(json);

String a[] = new String[jsonArr.size()];

String b[] = new String[jsonArr.size()];

String c[] = new String[jsonArr.size()];

for (int i = 0; i

a[i] = jsonArr.getJSONObject(i).getString("a");

b[i] = jsonArr.getJSONObject(i).getString("b");

c[i] = jsonArr.getJSONObject(i).getString("c");

}

for (int i = 0; i

System.out.print(a[i] " ");

System.out.print(b[i] " ");

System.out.print(c[i]);

System.out.println();

}

}

}

java怎么把数据转成json

有两种方法实现:

(1)直接转换:

创建JSONArray对象、JSONObject对象,通过put方法将其数据以键值对的形式填充,如例:

//假如有一个Java实体类Person,包括以下属性:phone、sex、married、address。

ArrayList persons = new ArrayList();

for (int i = 0; i

persons.add(new Person("138******67", "女", true, "北京朝阳区"));//填充Java实体类集合

}

JSONArray array = new JSONArray();// Json格式的数组形式

JSONObject obj;//json格式的单个对象形式

for (int i = 0; i

obj = new JSONObject();

//依次填充每一个Java实体对象

try {

obj.put("phone", persons.get(i).getPhone());//json通过put方式以key-value形式填充

obj.put("sex", persons.get(i).getSex());

obj.put("married", persons.get(i).getMarried());

obj.put("address", persons.get(i).getAddress());

array.put(obj);//将JSONObject添加入JSONArray

} catch (JSONException e) {

e.printStackTrace();

}

}

(2)通过GSON工具实现:

只需要创建GSON对象,通过toJson方法转换即可。如例:

//模拟Java数据

Person person = new Person("敏敏", 23, "女", "北京市海淀区");

//创建GSON对象

Gson gson = new Gson();

//调用toJson方法即可转换为字符串的json格式

String json = gson.toJson(person);
