How to deserialize nested JSON array in Java with Gson? [closed]

问题

Something wrong in creating structure of Java Model Class for Deserializing this type of json

[
  {
    "name": "Chapter 1",
    "samples": [
      {
        "name": "Topic 1",
        "uri": "video link url 1",
        "extension": "mpd"
      },
      {
        "name": "Topic 2",
        "uri": "video link url 2",
        "extension": "mpd"
      }
    ]
  },
  {
    "name": "Chapter 2",
    "samples": [
      {
        "name": "Topic 1",
        "uri": "video link url 1",
        "extension": "mpd"
      }
    ]
  }
]

This is what i am trying

This is my custom model Class

public class PostSample {
    @SerializedName("name")
    private String mName;
    @SerializedName("uri")
    private String mUri;
    @SerializedName("extension")
    private String mExtension;

    public PostSample(String name, String uri, String extension) {
        mName = name;
        mUri = uri;
        mExtension = extension;
    }
}

This will be nested outer Java Model class which i am trying to create nested model.

public class SampleData {

    @SerializedName("name")
    private String mName; //<------- i have to make it List array
    @SerializedName("samples")
    private List<PostSample> mSamples;

    public SampleData(String name, List<PostSample> samples) {
        mName = name;
        mSamples = samples;
    }
}

For json deserialization using GSON

Gson gson = new Gson();
  String json = getIntent().getStringExtra("dataVideo");//Here it pass string of json of above structure

  SampleData[] samplesData = gson.fromJson(json, SampleData[].class);

i checked the similer question but not able to make the model and deserialize it.
