[@farhadhabibullah548]

You are a freaking legend! everything you said makes sense, your logic is very clear. you are the "go to guy" after my java class at school, you always make everything crystal clear and easy to understand. Thank you so much for your hard work.

[@rameshbangaru2710]

Sir...interviewres asking..mostly asking HashMap and Hash table, Hashset..

[@vyavahareaditya5936]

Very good lecture sir , it was very understandable ❤️

[@sdetpavan]

Thanks

[@Harishkumar_24]

Everything is good neat and clear sir, but this "retainsAll, containsAll, removeAll" methods are available for List Interface also, because they are part of Collection Interface(So Please add this as a Note in your video Sir so that it will be helpful for us also)..!!

[@sdetpavan]

Welcome

[@Aditya-kumar-129]

During the 30:00-35:00 interval we have printed many times and each time we get the output in sequential manner.
Is it the coincidence or we get actually in sequential manner because in the beginning of video u tell that the sequence is not maintained in a hash

[@shahenshasha1507]

Excellent.....

[@sdetpavan]

Thanks

[@syedabdul2669]

Sir i have a question as you said
1. In case of ArrayList initial size is 10, when we are 11th element new ArrayList is created then what will be the size of new ArrayList, reason for asking is what will happen we try to insert 12th element into new arrayList, 12th element will be added into new arrayList or again new arrayList will be created
2. Same question what will be size of new Hashset when load factor has reached

[@saicharan4081]

Array list increase intialsize+half of its initial size. Suppose arraylist intial size 10 then 10+5(half of its initial size)=15 is the new size of arraylist.
This is the difference between arraylist and vector. Vector increase the size double of its initial size means 10(intial size)+10(adding intial size)= 20(double of its initial size).
Hashset also increase its double of its initial capacity when the 75% of intial capacity is filled.

[@syedabdul2669]

@@saicharan4081 Thanks for the input

[@selvakumara4051]

Thanks you so much sir

[@sdetpavan]

Most welcome

[@subbareddy2119]

how to get the particular element from the data by using set interface

[@pradeeprockzzz]

how come insertion order of the elements is preserved in Hashset? Everytime I print, it prints in same order as I inserted

[@ajasbakran6559]

load factor for arraylist is 0.75

[@AbhiSingh-ji4ge]

Please correct your video at 43 minutes. retainAll will not give intersection. ex: set1 { 1,2,3,4,5} and set2 {3,4,5,6} then set.addall(set2) will make set1 as {1,2,3,4,5,6} but set1.retainall(set2) will give {3,4,5,6} which is not an intersection between 1st set1 and set2.

[@krishnajayag8073]

if you comment out the addAll code and try retainAll you will get the intersection result as shown in the video. retainAll() method retains from set1 all of its elements that are contained in the specified collection set2.

[@gottepavani1838]

35:39 seconds out put the order in which u have entered in the same order v r getting

[@gottepavani1838]

U said hashset doesn't maintain any order but at 35 mits

[@kennyi1200]

Thanks

[@sdetpavan]

Welcome

[@aashiq-g6l]

removeall and retainAll is not union and intersection

[@yogeshkuthe8920]

Where is Stack implementation?

[@palyammanoj9104]

If we need 100 data items . how we need to add everytime is we need to use the "add" keyword??

[@amitkumarmohapatra8531]

Yes...

[@ruchitadhunna5381]

You have missed out a type "Sorted Set" here.

[@shruthiravula9203]

Hi sir plz provide pdf notes too sir 🙏
