Good explanation sir I like your videos and please upload more videos on logical programming and please help us to devolope our logical programming skills sir.

[vaibhavsrivastava]

We are still ending up with writing boilerplate code like isPresent() etc. Then what's wrong with writing null checking code on the object itself. Please explain as i don't see any benefit of using Optional class until i am answered. Thanks..

[sanketh]

The same thing can be done by checking if s[2] == null . This does not add much value

[akbarmdmca]

why optional i need ti use, we can do the samething by writing if else also

[DeepakPandey-ijbz]

Should optional to be used for other collections in Java? Please suggest.

[goku]

ArrayList<String> list=new ArrayList<>();
list.add("Mango");
list.add("Apple");
list.add("Banana");
list.add("Grapes");

Optional<ArrayList<String>>

list1.filter((item)->{ System.out.println(item); return true;}) or ist1.map((item)->{ System.out.println(item); return item;})

is there any way with filter and map of optional to iterate one by one on array element when i using this it returning me the whole array.
