JSON的基本数据格式及使用

 JSON的基本数据格式有这几种：
1.一个JSON对象——JSONObject
{"name":"胡小威" , "age":20 , "male":true}
答、直接解析
   JSONObject jsonObject = new JSONObject(json);  
            String name = jsonObject.getString("name");  
            int age = jsonObject.getInt("age");  
            boolean male = jsonObject.getBoolean("male"); 
2.一个JSON数组——JSONArray
[{"name":"胡小威" , "age":20 , "male":true},{"name":"赵小亮" , "age":22 , "male":false}]

答、先解析成数组，再一个个解析
    JSONArray jsonArray = new JSONArray(json);  
            for (int i = 0; i < jsonArray.length(); i++) {  
                jsonObject = jsonArray.getJSONObject(i);  
                String name = jsonObject.getString("name");  
                int age = jsonObject.getInt("age");  
                boolean male = jsonObject.getBoolean("male");  
3.复杂一点的JSONObject
{"name":"胡小威", "age"=20, "male":true, "address":{"street":"岳麓山南", "city":"长沙","country":"中国"}}
答、 先解析成json，再解析得到的json
   JSONObject jsonObject = new JSONObject(json);  
            String name = jsonObject.getString("name");  
            int age = jsonObject.getInt("age");  
            boolean male = jsonObject.getBoolean("male");  
            JSONObject addressJSON = jsonObject.getJSONObject("address");  
            String street = addressJSON.getString("street");  
            String city = addressJSON.getString("city");  
            String country = addressJSON.getString("country");  
            Address address = new Address(street, city, country);  
            Person person = new Person(name, age, male, address); 
4.复杂一点的JSONArray
[
{"name":"胡小威", "age"=20, "male":true, "address":{"street":"岳麓山南", "city":"长沙","country":"中国"}},
name":"赵小亮", "age"=22, "male":false, "address":{"street":"九州港", "city":"珠海","country":"中国"}}
]
答：写解析成数组，再解析成得到的json, 解析后得到json继续解析
jsonArray = new JSONArray(json);  
            for (int i = 0; i < jsonArray.length(); i++) {  
                jsonObject = jsonArray.getJSONObject(i);  
                String name = jsonObject.getString("name");  
                int age = jsonObject.getInt("age");  
                boolean male = jsonObject.getBoolean("male");  
                JSONObject addressJSON = jsonObject.getJSONObject("address");  
                String street = addressJSON.getString("street");  
                String city = addressJSON.getString("city");  
                String country = addressJSON.getString("country");
