[FIXED] How to Convert JSON to XML in java whilst keeping same order of XML attributes as in JSON

Issue

I have the below function

    public String convertToXml(String json) throws JSONException {
        JSONObject jsonObject = new JSONObject(json);
        String xml = XML.toString(jsonObject);
        return xml;
    }

that is converting JSON String to XML. However, some attributes are being swapped from their position for example

{"isbn": "123-456-222",  
 "author": 
    {
      "lastname": "Doe",
      "firstname": "Jane"
    },
"editor": 
    {
      "lastname": "Smith",
      "firstname": "Jane"
    },
  "title": "The Ultimate Database Study Guide",  
  "category": ["Non-Fiction", "Technology"]
 }

becomes

<editor>
    <firstname>Jane</firstname>
    <lastname>Smith</lastname>
</editor>
<author>
    <firstname>Jane</firstname>
    <lastname>Doe</lastname>
</author>
<isbn>123-456-222</isbn>
<title>The Ultimate Database Study Guide</title>
<category>Non-Fiction</category>
<category>Technology</category>

How can I make sure that the XML has the same order as JSON? I used org.json.XML from

        <dependency>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
            <version>20210307</version>
        </dependency>

Solution

I downloaded the Official JSON-java repository and changed \src\main\java\org\json\JSONObject.java constructor from

public JSONObject() {
        this.map = new HashMap();
    }

to

public JSONObject() {
        this.map = new LinkedHashMap();
    }

then i compiled it again to .jar file and include it to my project.
