如何使用googlegson解析json数组

我一直在关注JSON数组，我想解析它，将所有三个电子邮件地址转换成三个单独的变量。我希望这是通过谷歌GSON库来完成的。我们如何做到这一点

字符串JSONArray=

[
       {
          "Id": "0e9b73bc-cf32-48b4-88cc-ee4ff8c3a823",
          "FirstName": "Chris",
          "LastName": "Rogers",
          "Height": "180cm",
          "Weight": "74kg",
          "location": "UK",
          "email": "chris.rogers@test.com"
       },
       {
          "Id": "0e9b73bc-7cd7-48b4-88cc-ee4ff8c76vcv",
          "FirstName": "Lavina",
          "LastName": "Langer",
          "Height": "170cm",
          "Weight": "63kg",
          "location": "Poland",
          "email": "lavina.rogers@test.com"
       },
       {
          "Id": "213jdsj-cf32-48b4-1119hshjakakaaka",
          "FirstName": "Mike",
          "LastName": "Harford",
          "Height": "184cm",
          "Weight": "80kg",
          "location": "Paris",
          "email": "mike.harford@test.com"
       }
    ]

我写了一些代码

Gson myGson = new Gson();
JsonParser jsonParser = new JsonParser();
JsonArray userArray =jsonParser.parse(jsonarrays).getAsJsonArray();
List messageArray = new ArrayList();
    for (JsonElement aUser : userArray ){
        User aTwitterUser = myGson.fromJson(aUser, User.class);
        messageArray.add(aTwitterUser);
}

我所犯的错误

显然，您的JSON是错误的，因为com.google.gson.JsonSyntaxException状态为。尝试从每个对象中删除最后一个逗号。也许格森不喜欢这样。
