我们可以通过JSONObject类将这个JSON字符串转换为JSONObject对象,并获取其中的int数组。下面是示例代码: importorg.json.JSONObject;importorg.json.JSONArray;publicclassMain{publicstaticvoidmain(String[]args){StringjsonString="{\"numbers\": [1, 2, 3, 4, 5]}";JSONObjectjsonObject=newJSONObject(jsonStri...
json_object_new分配json对象空间,设置json对象类型,并设置基本的json对象清理函数json_object_generic_delete。 structjson_object*json_object_new_object(void){structjson_object*jso=json_object_new(json_type_object);if(!jso)returnNULL; jso->_delete = &json_object_object_delete; jso->_to_json_strin...

Person p = new Person(); p.setName(jObject.getString("name")); p.setGender(jObject.getString("gender")); p.setAge(jObject.getInt("age")); JSONArray jArray = jObject.getJSONArray("hobby"); Hobby hobby = new Hobby(); List<String> list = new ArrayList<>(); ...
JSONObject 就是把其他形式和json形式对象相互转化。 JSONObject可以很方便的转换成字符串,也可以很方便的把其他对象转换成JSONObject对象。 生成jsonObject的几种形式 1,new JSONObject JSONObject zhangsan = new JSONObject(); try { //添加 zhangsan.put(“name”, “张三”); zhangsan.put(“age”, 18.4)...
用法详解:通过无参构造函数创建一个全新的、不包含任何键值对的 JSONObject 对象,用于后续添加键值对操作。 2. 从 JSON 字符串创建 JSONObject 对象:`JSONObject jsonObject = new JSONObject("{\"name\":\"John\",\"age\":30}");`。用法详解:将符合 JSON 格式的字符串作为参数传递给 JSONObject 的构造...
JSONObject(String) Creates a new JSONObject with name/value mappings from the JSON string. JSONObject(JSONObject, String[]) Creates a new JSONObject by copying mappings for the listed names from the given object. JSONObject(IntPtr, JniHandleOwnership) A constructor used when creating manage...
JsonObject object = Json.createObjectBuilder().build(); For example 2: The following JSON { "firstName": "John", "lastName": "Smith", "age": 25, "address" : { "streetAddress": "21 2nd Street", "city": "New York", "state": "NY", "postalCode": "10021" }, "phoneNumber": ...
// convert from JSON: copy each value from the JSON object ns::person p { j["name"].template get<std::string>(), j["address"].template get<std::string>(), j["age"].template get<int>() }; It works, but that's quite a lot of boilerplate... Fortunately, there's a better...
