Very informative video... It would be helpful if you could explain while making video about the scenarios where we can use these concepts in web testing...

Second method is more useful and kindof update to the market standards ✊🏼

both are very good approach and I have no doubt on that ..I applied this on both HashSet an LinkedHashSet and it works .The difference is only insertion order where LinkedHashSet preserve insertion order .but why you mention only LinkedHashSet why not both??? is there any other issue Mr Naveen ??thank you very much.

Hello Naveen, Thanks a lot for sharing your knowledge. Just one query I have one.. any specific reason for choosing LinkedHashSet over HashSet, as this can be done using HashSet as well. Kindly let me know.. Thanks in Advance!!

//Using distinct and iterator() List list = new ArrayList(Arrays.asList(1,34,2,67,1,9,2,56,34,11,55)); Iterator it =list.stream().distinct().iterator(); while(it.hasNext()) { System.out.println(it.next()); }

Thank you Naveen If we print object of linkedhashset even then we are about to remove duplicate values. Why do we create new arraylist again ?

@chetandhiman4735 2 жыл бұрын

Its because we want array list at the end after remove value

First of all super content . Learn something new everytime i start a playlist :) I faced the same question in hacker rank . i used 2 for loops to iterate and remove the duplicate elements from the Integer arrayList , but the code could only pass 7 out of 10 data input scenarios . But if i use the any of 2 methods in video all 10 data input scenarios are passed . Could you please explain as to how using these 2 methods would handle any sort of input as compared to using regular for loops .

I have a query. why use LinkedHashSet. why not HashSet ? hashset has better performance in retrieving elements. Any specific reason ?

do we have to use LinkedHashSet, or can we just use HashSet?

@sagarnayak3628 3 жыл бұрын

If order is not of concern, you can use HashSet. LinkedHashSet maintains original(insertion) order.

@SameerKumar-yu1xi 2 жыл бұрын

Hello Naveen.... In 1st approach we can also use HashSet right .. The only purpose of using LinkedHashSet is to maintain output in ordered....right? Or any other reason are there?

@gugapriyaramasamy6200 Жыл бұрын

Both HashSet and LinkedHashSet maintains the order

without creating arraylist after linkedhashset,we are geeting result in sysout.

@user-su1pt5eu5e 3 жыл бұрын

Sir here as we use LInkedHashSet on ArrayList Should the order be maintained or not?

Hi Brother, Just one query why can't we create an object of HashSet... I mean: ArrayList remduplicate = new ArrayList(Arrays.asList(1,2,3,4,5,1,2,3,4)); Set uniqset = new HashSet(remduplicate); ArrayList uniqueArlist = new ArrayList(uniqset); System.out.println("Unique value in array list " + uniqueArlist); Any specific reason to create an object of LinkedHashSet??

@hetshah1440 3 жыл бұрын

If you create a HashSet then it might be possible that output is not in the form of order which you insert.

@priyotoshmaji2859 3 жыл бұрын

But why linkedhashset not only hashset can you explain pls?

@blablagswjsvsns134 3 жыл бұрын

We can use hashmap . It's not better than these 2 ways but we can use that too.😀

@django4084 3 жыл бұрын

How? What's the key here? the numbers? Seems too much of a workaround.

@poojarajput827 7 ай бұрын

Hashset internally use hashmap to remove duplicates.

@barunpundhir2898 4 ай бұрын

in the LinkedHashSet...why we are not printing linkedHasSet it will give array list with no duplicate value. we are printing extra line "ArrayList numbersListWithoutDuplicates = new ArrayList(linkedHashSet);" @naveen
