Java代码

注：首先导入org.json下面的包

package com.sun;  

import org.json.JSONArray;  
import org.json.JSONException;  
import org.json.JSONObject;  

public class Test {  

    public static void main(String args[]) throws JSONException {  
        String jsonContent = "{'hello':world,'abc':'xyz'}";  
        JSONObject jsonObject = new JSONObject(jsonContent);  
        String str1 = jsonObject.getString("hello");  
        String str2 = jsonObject.getString("abc");  
        System.out.println(str1);  
        System.out.println(str2);  

        System.out.println("------------------");  
        jsonContent = "[{'hello':333,'abc':'false','xyz':{'a':1,'b':'ab'}},{'hello':555,'abc':'true','xyz':{'a':2,'b':'ba'}}]";  
        JSONArray jsonArray = new JSONArray(jsonContent);  
        for(int i=0;i<jsonArray.length();i++){  
            JSONObject jsonobject2=jsonArray.getJSONObject(i);  
            int value1=jsonobject2.getInt("hello");  
            boolean value2=jsonobject2.getBoolean("abc");  
//          String value3=jsonobject2.getString("xyz");  
            JSONObject jsonobject3=jsonobject2.getJSONObject("xyz");  
            int value4=jsonobject3.getInt("a");  
            String value5=jsonobject3.getString("b");  
            System.out.println(value1);  
            System.out.println(value2);  
            System.out.println(value4);  
            System.out.println(value5);           
        }  

    }  
}  
输出结果  
world  
xyz  
------------------  
333  
false  
1  
ab  
555  
true  
2  
ba
