問題描述:package?testJSON;

import?net.sf.json.JSONArray;

import?net.sf.json.JSONObject;

public?class?TestJson2?{

public?static?void?main(String[]?args)?{

String?str?=?"{"data":[{"id":"1","name":"name1"},"

+?"{"id":"2","name":"Zname2.0","name":"Dname2.1","name":"Pname2.2","name":"Zname2.3"},{"id":"3","name":"name3"},]}";

//

JSONObject?jsonObject?=?JSONObject.fromObject(str);

JSONArray?result?=?jsonObject.getJSONArray("data");

//System.out.println(result);

for?(int?i?=?0;?i?

String?id?=?result.getJSONObject(i).getString("id");

if(id.equals("2")){

String?name?=?result.getJSONObject(i).getString("name");

System.out.println(name);//["Zname2.0","Dname2.1","Pname2.2","Zname2.3"]

//怎么取出["Zname2.0","Dname2.1","Pname2.2","Zname2.3"]中的"Dname2.1"????

}

}

}

}

問題解答:String[]?strs=name.split(",");

List?asList?=?Arrays.asList(strs);

System.out.println(asList.get(1));

先分割成數(shù)組,然后轉(zhuǎn)成集合,最后直接取下標
