How to add an empty JSON Array to JSON Object in a specific order

问题

以下是JSON结构的翻译部分：

  1. {
  2.   "pricing": {
  3.     "quantity": 4200,
  4.     "minQuantity": 10,
  5.     "pricePerUnit": {
  6.       "amount": 0.2865,
  7.       "currency": "USD"
  8.     },
  9.     "discounts": []
  10.   },
  11.   "description": "test",
  12.   "guaranteedDeliveryTime": "testTime",
  13.   "offerType": "Currency"
  14. }

以下是代码部分的翻译：

  1. Map<String, Object> pricePerUnit = new LinkedHashMap<>();
  2. pricePerUnit.put("amount", 0.2865);
  3. pricePerUnit.put("currency", "USD");
  5. Map<String, Object> pricing = new LinkedHashMap<>(8, 0.6f, false);
  6. pricing.put("quantity", 2342);
  7. pricing.put("minQuantity", 2342);
  8. pricing.put("pricePerUnit", pricePerUnit);
  9. pricing.put("discounts", new JSONArray());
  11. JSONObject obj1 = new JSONObject();
  12. obj1.put("pricing", pricing);
  13. obj1.put("guaranteedDeliveryTime", "testTime");
  14. obj1.put("description", "test");
  15. obj1.put("offerTime", "Currency");

以下是最终输出的翻译部分：

  1. {
  2.   "guaranteedDeliveryTime": "testTime",
  3.   "description": "test",
  4.   "pricing": {
  5.     "quantity": 2342,
  6.     "minQuantity": 2342,
  7.     "discounts": [],
  8.     "pricePerUnit": {
  9.       "amount": 0.2865,
  10.       "currency": "USD"
  11.     }
  12.   },
  13.   "offerTime": "Currency"
  14. }

希望这些翻译能帮助你理解JSON结构和相关的代码。如果你需要进一步的帮助，请随时提出问题。

I am trying to create this structure for a JSON -

  2.     {
  3.       &quot;pricing&quot;: {
  4.         &quot;quantity&quot;: 4200,
  5.         &quot;minQuantity&quot;: 10,
  6.         &quot;pricePerUnit&quot;: {
  7.           &quot;amount&quot;: 0.2865,
  8.           &quot;currency&quot;: &quot;USD&quot;
  9.         },
  10.         &quot;discounts&quot;: []
  11.       },
  12.       &quot;description&quot;: &quot;test&quot;,
  13.       &quot;guaranteedDeliveryTime&quot;: &quot;testTime&quot;,
  14.       &quot;offerType&quot;: &quot;Currency&quot;
  15.     }

I have came up with a solution that is pretty close. However the ordering seems a bit off.
Here is the code I am using -

  1. Map&lt;String, Object&gt; pricePerUnit = new LinkedHashMap&lt;&gt;();
  2.     pricePerUnit.put(&quot;amount&quot;, 0.2865);
  3.     pricePerUnit.put(&quot;currency&quot;, &quot;USD&quot;);
  5.     Map&lt;String, Object&gt; pricing = new LinkedHashMap&lt;&gt;(8, 0.6f, false);
  6.     pricing.put(&quot;quantity&quot;, 2342);
  7.     pricing.put(&quot;minQuantity&quot;, 2342);
  8.     pricing.put(&quot;pricePerUnit&quot;, pricePerUnit);
  9.     pricing.put(&quot;discounts&quot;, new JSONArray());
  11.     JSONObject obj1 = new JSONObject();
  12.     obj1.put(&quot;pricing&quot;, pricing);
  13.     obj1.put(&quot;guaranteedDeliveryTime&quot;, &quot;testTime&quot;);
  14.     obj1.put(&quot;description&quot;, &quot;test&quot;);
  15.     obj1.put(&quot;offerTime&quot;, &quot;Currency&quot;);

And the final output is as follows.

  1.     {
  2.       &quot;guaranteedDeliveryTime&quot;: &quot;testTime&quot;,
  3.       &quot;description&quot;: &quot;test&quot;,
  4.       &quot;pricing&quot;: {
  5.         &quot;quantity&quot;: 2342,
  6.         &quot;minQuantity&quot;: 2342,
  7.         &quot;discounts&quot;: [],
  8.         &quot;pricePerUnit&quot;: {
  9.           &quot;amount&quot;: 0.2865,
  10.           &quot;currency&quot;: &quot;USD&quot;
  11.         }
  12.       },
  13.       &quot;offerTime&quot;: &quot;Currency&quot;
  14.     }

The ordering seems off. I assume it is an issue as I am using a LinkedHashMap. I also tried setting the access order to see if that would change the ordering. Any advice would be greatly appreciated. Thanks.

A JSONObject is an unordered collection of name/value pairs.
