Expecting more on this content especially your explanation on limit(),skip() gives me clear picture on usage of such methods and it is really different from my point of understanding what i read from websites with examples.Thanks a lot team and it will good if you do on peek(),reduce() and also on parallel streams etc.

[@ravindracharyvadyarapu]

Nice explanation.. I have faced these questions in the interview. Can you also list employees in sorting order based on name and salary.

[@CodeDecode]

Thanks Ravindra. Sure we will include these too In same question 👍🙂😃

[@ravindracharyvadyarapu]

@@CodeDecode I have used Comparator.comparing().thenComparing(). Please let us know if any alternate solution available.

[@ajaykrishna441]

That question was already covered in this channel. Once go through all videos.

[@slowstarter5720]

Thank you for putting efforts in providing the awesome content with in detailed explanation & demo. As far as this video's concerned, usage of skip & limit as a combination is something that is missed I guess(which might be useful for getting nth highest salary ).
Could you please make a tutorial or interview questions video(s) for MyBatis as well in near future.
Thanks

[@CodeDecode]

Sure thanks 👍🙂

[@komalagrawal5597]

I have a question, For last problem what if some employee have the same salary. then how we can fetch ?

[@harshavardhanpasumarthi4249]

I too have the same doubt. Not only in the last case, In case of first 3 highest salaried employees also, we can't get expected output with limit and skip. How to overcome this problem. Please explain @CodeDecode

[@karthikeyanrm3446]

Code decode Team - Because of your content even today I cleared interview of a very good company, have got so many offers. You guys are really awesome - no words to appreciate 🙂

[@alok7485]

//Please explain how to Write Java 8 program to return word as a list value and its length as a key in descending sorting
order from below sentence, -Input => String statement = "Hello World My name is Jane and I hate Mango Fruit";
Output=> {5 = [“Hello”, “World”, “Mango”, “Fruit”], 4 = [“name”, “Jane”, “hate”],
3 = [“and”], 2 = [“My”, “is”], 1 = [“I”]}

[@CodeDecode]

Pseudo code :
Split string by space, create list from array of string.
Open stream on list
Group by string's length n values will become list of all strings of that length👍

[@CodeDecode]

That's pseudo code. If you want we will create a video on this👍
