Actual filtering is happening due to the feature of set and due to Collections.frequency operation. To prove this try collecting it to a list instead of set

[@priyaranjan1973]

Set all=l.stream().filter(
n-> l.stream().filter(x->x==n).count()>1
).collect(Collectors.toSet());

[@spider-maniac300]

This was good !

[@mohammedsufi4649]

Thank you so much for the video. Very useful. Please keep it up

[@deepanshurathore9661]

I think Set method is optimised take O(n) time . freq method might be take O(n2) time

[@AnilSharma-fb3ze]

[@muthikinaveen2195]

We have distinct functionality in streams. numbers.stream().distinct();

[@arunsinghrajpoot5363]

Thanks bro

[@ankarigaripriyanka8306]

never heard we could do it this way also

[@sanoopk8847]

Waiting for more videos

[@mastermind6269]

second solution would not work if we have accourence more than two times, we have to use distinct() method there!

[@karamjitsinghsehdev3451]

How to get duplicates with their counts and return map?

[@madarauchiha-dr5ws]

No need to use collectors.toset(), collectors.toList() will work. Can someone please correct me if I am wrong

[@ruishizhang1159]

List won't work if there is a tripled number
