如何使用简单的 json 读取 Java 中的 JSON 文件？

Question

If I have a JSON like this:

{
  "name": "Johnny",
  "Gender": {
    "male": true,
    "female": false
  },
  "What does Johnny likes?": ["Travels", "Woman"],
  "Travels": [
    {
      "Country": "Spain",
      "City": "Madrid"
    },
    {
      "Country": "Greece",
      "City": "Kalokairi"
    }
  ]
}

I know that I can do this to access to name :

object.getString("name");

To access gender I can do this:

JSONObject gender = (JSONObject) object.get("Gender");
gender.get("male");
gender.get("female");

To access What does Johnny likes? I can:

JSONArray likes = (JSONArray) objet.get("What does Johnny likes?");
        Iterator<String> iterator = likes.iterator();
        while (iterator.hasNext()) {
            //code here
        }

But how do I access Travels ? I'm really not sure to understand it?

Answer 1

did you, try this?

JSONArray travels = (JSONArray) objet.get("Travels");
for(int j=0;j<travels.length();j++){
    JSONObject travel = travels.getJSONObject(j);
}
