Java 在这种情况下，如何解析JSON数组中的值

我正在尝试解析这个JSON

{
    "details": {
        "Service Tax": [
            {
                "tax_order": 3,
                "inclusive": [
                    {
                        "Discount": 1,
                        "Service Charge": 1
                    }
                ]
            }
        ],
        "VAT": [
            {
                "tax_order": 3,
                "inclusive": [
                    {
                        "Discount": 1,
                        "Service Charge": 1,
                        "Item": 1
                    }
                ]
            }
        ]
    },
    "vendor_id": 1
}

是否可以提取数组中该值的字段

例如，如果是服务税，我需要获取折扣和服务费

例如，如果是增值税，我需要获取折扣、服务费和物品

参考此链接--此链接中的答案很好--一旦获得这些值，您希望如何处理它们？“目前还不清楚。@JonSkeet，一旦我得到它们，我想用字符串和ArrayList的组合存储在HashMap中。这并不能给我们提供更多的信息。。。但是，您可能希望查看JSONObject.keys以找出特定对象的键。。。

package test;

import org.json.JSONArray;
import org.json.JSONObject;

public class Tester {


    public static void main(String args[]) throws Exception

        String json = "{\r\n" +

         String[] json_order = new String[]{"Service Tax", "VAT"};

            JSONObject inputRqstJson = new JSONObject(json);
            JSONObject details_json = inputRqstJson.getJSONObject("details");

                for(String tax_name : json_order)
                {
                JSONArray tax_nameJarray = details_json.getJSONArray(tax_name);
                System.out.println(tax_nameJarray);
                }

    }
