将这些JSON解析为对象集合并使用比较器使用首选字段对其进行排序。

Parse these JSON to Collection of Objects and use comparator to sort it using your preferred field.

• 使用GSON将其解析为对象集合

• Use GSON to parse it to collection of objects

示例：

import com.google.gson.Gson;

class Person {
  private int age;
  private String name;
}

String json = "{'age':22,'name':'Jigar'}";
Gson gson = new Gson();
TestJsonFromObject obj = gson.fromJson(json, Person.class);  

如果你想从Object创建JSON。

If you want to create JSON from Object.

Person p = new Person();
p.setName("Jigar");
p.setAge(22);
String jsonStr = new com.google.gson.Gson().toJson(obj);
