I have a JSON array and trying to sort it by value.

Trying to update json data
private static String modifyJsonData(String jsonData, List connectionIds, String selector) {

I’ve seen some examples of transforming JSON but they are 8-11 yrs old and wanting to see if there is another approach.

Is anyone willing to help me with changing this script to use a json file instead of storing the usernames and passwords in an array? All of the other login scripts I find that use the json file, do not redirect to index.php page after login. I am already using this one but putting all of the credentials in this array is tiresome
