Adding object of various type to an arraylist

Question

Im having the following objects in my class,

LatestRingtones latestRingtones;
MostDownloadedSongs mostDownloadedSongs;
LatestDialoges latestDialoges;

LatestRingtones, MostDownloadedSongs,LatestDialoges extends sugarrecord.

So, I have created an arraylist to store object of various types as follows,

public List<SugarRecord> streamingTrackList = new ArrayList<>();

I tried to add the latestRingtones as follows

streamingTrackList.add(latestRingtones);

but im getting an error like List can not be applied to jsonarray

How can i be able to convert the jsonarray to list and add it to streaming track or is there any ways through which I can add object of various types to streamingTrack?

How are you getting this latestDialogeTen? Is it a list or object? More code will be helpful to understand your situation. — mushfek0001

Why are you trying to store a random assortment of things in one array? — Raedwald

For a question about code not working we need a Short, Self Contained, Correct (Compilable), Example (maybe not always, but I should say we do in this case). You may think it’s much work at first, but in the end I believe you’ll find it worthwhile. — Anonymous

You're asking a question about an error message you don't understand, related to some code. So, your question should contain the code causing the error, and the exact and complete error message you got. — JB Nizet

If latestRingtones is a json array you can not add a JsonArray into ArrayList . So simply convert you jsonarray in Object array using any know library (gson , simple json etc) and than add the objects into your ArrayList
