java - JSON 应该如何存储如下值

Question

我想将 Json 值存储到下面的数组中。

如果只有单个事件，

private static final String[] Eventname = {"Wedding"}
private static final String[][] Bid= {{"Studio 1"}}
private static final String[][] location= {{"Ernakulam"}}

如果有多个事件和多个投标人，

private static final String[]  Eventname = {"Wedding","Funeral"};
private static final String[][] Bid={{"Studio 1","Studio 2","Studio 3"},
                {"Studio 1","Studio 2","Studio 3"}}; 
private static final String[][] location= {{"Ernakulam"},{"Kollam"}}

我已经为 eg 创建了一个 json:

[
  {
    "Event": "Wedding",
    "Studios": [
      "Studio 1","Studio 2"
    ],
    "Location": ["Ernakulam","Bangalore"]
  },
  {
    "Event": "Birthday",
    "Studios": [
      "Studio 1"
    ],
    "Location": ["Ernakulam"]

  },
  {
    "Event": "Engagement",
    "Studios": [
       "Studio 1","Studio 2","Studio 2"
    ],
    "Location": ["Ernakulam","Bangalore","Angamaly"]
  }
]

但是我怎样才能得到这个 json 值并将它存储在上面的数组中。

Answer 1

java中有多个json解析库。
例如，您可以使用 javax.json。

在那种情况下你可以做

try(JsonReader jsonReader = Json.createReader(new StringReader(yourJsonString))){
 JsonArray arr = jsonReader.readArray();
 ... run through the entries in arr here and fill your arrays accordingly ...
}

但我应该指出，您尝试创建的结构毫无意义，而且非常不像 Java。我建议您创建适当的类来表示 Event、Venue 和 Bidding。它最终会让你的生活更轻松......
