Thank you so much for such a wonderful content, We use Optional classes to check NullpointerExceptions but I have doubt that instead of null check we are converting that data/value as Optional object and we are checking whether the value is there are not and then we are doing rest of the operation its almost similar like doing "NULL" checks so what is the advantage of using Optional on top of NULL checks

[SurajYadav-ydcu]

Nice video, Just a small point to add, Optionals in java is entirely to notify that a method can return a null or empty value and also to have some ease of null exceptions.
We must always avoid to make a local variables having Optionals as its type, it creates over head for the system with an extra wrapping of class, making more work for compilers and GC's.
Thus we must know the use case of Optionals<E>
Open for discussions

Thanks
