我们要操作的Json数据如下：
{"total":2,"class":"二年级","members":[{"age":18,"name":"李小红","score":95},{"age":28,"name":"王尼玛","score":85}]}
我们先用CreateJson()方法生成Json数据，然后把所有属性都解析出来。
-
package Myclass;
-
-
import org.json.JSONArray;
-
import org.json.JSONObject;
-
-
public class Test {
-
-
public static void main(String[] args) {
-
//解析Json--传入Json字符串
-
JSONObject my_json=new JSONObject(CreateJson());
-
int total=my_json.getInt("total");
-
System.out.println("总数为："+total);
-
-
String class_name=my_json.getString("class");
-
System.out.println("班级为："+class_name);
-
-
JSONArray members=my_json.getJSONArray("members");
-
for(int i=0;i<members.length();i++)
-
{
-
JSONObject member=(JSONObject)members.get(i);
-
System.out.println("姓名："+member.getString("name")+" 年龄："+member.getInt("age")
-
+" 成绩："+member.getInt("score"));
-
}
-
-
}
-
-
public static String CreateJson()
-
{
-
JSONObject my_json=new JSONObject();
-
my_json.put("class", "二年级");
-
my_json.put("total", 2);
-
-
JSONArray members=new JSONArray();
-
//第一个同学
-
JSONObject member1=new JSONObject();
-
member1.put("name", "李小红");
-
member1.put("age", 18);
-
member1.put("score", 95);
-
members.put(member1);
-
//第二个同学
-
JSONObject member2=new JSONObject();
-
member2.put("name", "王尼玛");
-
member2.put("age", 28);
-
member2.put("score", 85);
-
members.put(member2);
-
my_json.put("members", members);
-
-
return my_json.toString();
-
}
-
-
}
