使用org.json

Question

我正在创建一个导入和导出相同键的JSON的应用程序。导入JSON文件会经常更改，我不想每次JSON文件添加新密钥时都更新应用程序。

这是针对Java Swing应用程序的。用户将能够修改存在的导入JSON字段并将其应用于导出JSON。

Fruit.java

public class Fruit {
    private String name;
    private String description;
    private int price;
    private String[] colors;

   public Fruit(JSONObject obj) {
        this.name = obj.optString("name");
        this.description = obj.optString("description");
        this.price = obj.optInt("price");

        JSONArray jArr = obj.optJSONArray("colors");
        String[] sArr =  new String[jArr.length()];
        for(int i = 0; i < sArr.length; i++) {
            sArr[i] = jArr.optString(i);
        }
        this.colors = sArr;
   }
}

初始导入JSON

{
    "name": "Apple",
    "description":"It is delicious",
    "price": 20,
    "colors":["red","green","yellow"]
}

未来导入JSON

{
    "name": "Apple",
    "description":"It is delicious",
    "price": 20,
    "colors":["red","green","yellow"],
    "fruit": true,
    "types": ["gala", "fuji", "golden delicious", "honeycrisp"],
    "soldAt": ["Corner Store", "Farmers Market", "Walmart"]
}

注意：导出JSON将具有与导入JSON完全相同的格式。

未来导出的JSON

{
    "name": "Apple",
    "description":"It is very delicious",
    "price": 5,
    "colors":["red","green","yellow"],
    "fruit": true,
    "types": ["gala", "fuji", "golden delicious", "honeycrisp", "red delicious"],
    "soldAt": ["Corner Store", "Farmers Market"]
}

我想知道使用org.json库将新密钥添加到导出JSON的最佳方法是什么？
