The way you are explaining the logic while writing it is crystal clear even to a beginner. Thanks a lot for sharing all the videos. I have also tried the above program using Set and it worked.

[varshamishra]

I am loving coding only because the way you explain every logic Sir... Thank you🙏

[mohammadsuhail]

TBH your code complexity is more challenging for beginner level coders But seriously it motivates to learn more and more...!! Thank you :)

[Tistasful]

Thank you sharing your knowledge with the whole world, you are doing a great job and you are a role model!

The best channel for Automation. Kudos to you Naveen. Keep up the good work.

To extract all the keys of map I have used Iterator and it’s really nice that it can be achieved using Set as well in simple way.
Thank you so much Naveen Bhayya.

Hi Naveen,
I think this can be solved using Set also, without involving Map, as below:


String[] strArray = inputString.split("\\s");


HashSet<String> set = new HashSet<String>();

for (String arrayElement : strArray)
{
if(!set.add(arrayElement))
{
System.out.println("Duplicate Element is : "+arrayElement);
}
}

Always the best Naveen...you are superb...

[parimalaperiyasamy]

Hello Naveen,
Thanks for your vedio. Its really understandable.Here are my questions, if you find time, please answer and that will help me.


1. What is the role of toLowerCase() method here, Why its not converting upper case in input to Lowercase
2. Can we use entrySet instead of Keyset for traversing the elements?

[anvitaravirajmetri]

Small Suggestion, If you explain the same thing with diagram of array and hashmap would give more clarification

[zakir]

Hi Naveen good explanation, is there any other method to find the duplicate.

[ramupanjala]

Thanks for the video .I am looking count JSON response duplicate ? Can we use this concept in groovy ?

[karthickmohan]

Thank so much bro its very useful for my interview
