如何使用JSONObject在Java中创建正确的JSONArray

Question

我如何使用JSONObject在Java中创建如下所示的JSON对象？{    "employees": [        {"firstName": "John", "lastName": "Doe"},         {"firstName": "Anna", "lastName": "Smith"},         {"firstName": "Peter", "lastName": "Jones"}    ],    "manager": [        {"firstName": "John", "lastName": "Doe"},         {"firstName": "Anna", "lastName": "Smith"},         {"firstName": "Peter", "lastName": "Jones"}    ]}我找到了很多示例，但没有找到我确切的JSONArray字符串。

可以编写小的可重用方法来创建人员json对象，以避免重复代码

JSONObject  getPerson(String firstName, String lastName){

   JSONObject person = new JSONObject();

   person .put("firstName", firstName);

   person .put("lastName", lastName);

   return person ;

} 

public JSONObject getJsonResponse(){

    JSONArray employees = new JSONArray();

    employees.put(getPerson("John","Doe"));

    employees.put(getPerson("Anna","Smith"));

    employees.put(getPerson("Peter","Jones"));

    JSONArray managers = new JSONArray();

    managers.put(getPerson("John","Doe"));

    managers.put(getPerson("Anna","Smith"));

    managers.put(getPerson("Peter","Jones"));

    JSONObject response= new JSONObject();

    response.put("employees", employees );

    response.put("manager", managers );

    return response;

  }
