问题描述: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"????
}
}
}
}
问题解答:String[] strs=name.split(",");
List asList = Arrays.asList(strs);
System.out.println(asList.get(1));
先分割成数组,然后转成集合,最后直接取下标
