如何使用 GSON 将 List 转换为 JSON 对象

I have a List which I need to convert into JSON Object using GSON. My JSON Object has JSON Array in it.

public class DataResponse {

    private List<ClientResponse> apps;

    // getters and setters

    public static class ClientResponse {
        private double mean;
        private double deviation;
        private int code;
        private String pack;
        private int version;

        // getters and setters
    }
}

下面是我的代码，其中我需要将列表转换为JSON对象，其中包含JSON数组-

public void marshal(Object response) {

    List<DataResponse.ClientResponse> clientResponse = ((DataResponse) response).getClientResponse();

    // now how do I convert clientResponse list to JSON Object which has JSON Array in it using GSON?

    // String jsonObject = ??
}

到目前为止，我的列表中只有两项——所以我需要像这样的JSON对象-

{  
   "apps":[  
      {  
         "mean":1.2,
         "deviation":1.3
         "code":100,
         "pack":"hello",
         "version":1
      },
      {  
         "mean":1.5,
         "deviation":1.1
         "code":200,
         "pack":"world",
         "version":2
      }
   ]
}

What is the best way to do this?
