在javax.json.JsonArray中更改json元素的值

Question

[
    {
        "key":"key1",
        "value":"key one value",
        "description":""
    },
    {
        "key":"key2",
        "value":"key two value",
        "description":""
    },
    {
        "key":"key3",
        "value":"key three value",
        "description":""
    },
    {
        "key":"key4",
        "value":"key four value",
        "description":""
    },
    {
        "key":"key5",
        "value":"key five value",
        "description":""
    }   
]

This above is my an example json file I'm working with, I'm putting it into an JsonArray like this

BufferedReader reader = Files.newBufferedReader(file,
                Charset.defaultCharset());
JsonReader jsonReader = Json.createReader(reader);
JsonArray array = jsonReader.readArray();

And My issue is I want to access the JsonArray and change the value part of each json element but is unable to do this. the collection doesn't seem to offer anyways to replace values of any json element. Do you know anyways I could achieve what I'm set to to do?? PS: also open to suggestions on using an alternative collection, but please educate me on why should I choose said collection.

Since you did not mention which JSON library you are using, you can use element method if you are using json-lib to replace an element

public JSONArray element(int index,
                         Object value)

If you want to update a specific attribute of the JSONObject element, you can try something like below

array.getJSONObject(0).put("key","new key value")

Please note that I have used hard coded value 0 for demonstration purposes.
