Thank you sir gud explanation 😊

[@sdetpavan]

My pleasure!

[@satyajitsahoo30]

In priority queue insertion order based on default natural sorting, duplicated allowed, hetrogeneous are not allowed , null insertion not possible .

[@kya_karoge_jaanke1607]

We admire your work sir💫💫

[@sdetpavan]

Thanks

[@keyurpatel-r3d]

I have to mention two points.
1) LinkedList implements Deque
2) Insertion order is not maintained in the Priority queue.

[@ಯಾತ್ರಿಕ]

Yes , Insertion order is not maintained in priority queue.

[@chiranjeevishankarn7904]

1) Priority queue maintains natural ordering of the language
2) Priority queue creates default size of 11 in the memory

[@bestjobs9762]

superb and excellent. explained in a very simple manner. remembered my college days.

[@sdetpavan]

Thanks

[@rocked789]

@SDET- QA Automation Techie please correct it ..priority queue will not preserve insertion order

[@jaickey09]

Got few insights, thanks

[@preetamvarun9219]

Thank You!

[@sdetpavan]

Welcome

[@dipakagarwal1538]

You mentioned that offer() method returns false if insertion is not successful, but in the code example, it threw ClassCastException.

[@mvs69]

yes

[@rameshrongala922]

Thanks sir.

[@sdetpavan]

Most welcome

[@icanalsocode]

Sir, in priority queue insertion order is not maintained. Otherwise, I have followed all your video. Your videos are superb,

[@Mysterious_universe601]

Thank you sir

[@sdetpavan]

Welcome

[@umamaheshballa2193]

thank you so much sir given valuable information to us , sir any planing to reaming collection topics

[@ayushjain7555]

cant we use for loop in case of arrayList?

[@icanalsocode]

Yes

[@muttamounika]

sir,in priority queue is insertion order preserved????

[@pavanMudavath822]

sir what about queue interfaces???

[@saurabh_purandare]

Great Explanation!
Just want to confirm 20:40, Is insertion order preserved in PriorityQueue too?
I think the elements are stored based on the priority order which is ascending by default.
can you please confirm?
Thanks

[@bhuvanchandmaddi800]

Yes Insertion order is preserved PriorityQueue too , 8:06

[@charanbudama2601]

Insertion orer is not preserved in priority Queuw

[@sonalkanchan147]

Insertion order is not preserved...que.add("A");
que.add("om");
que.add("Tom");
que.offer("A");
System.out.println(que);
Output:[A, A, Tom, om] @SDET could you confirm?

[@snehamhetre2336]

I also have the same doubt.

[@gokulkrishnan291]

maximum ASCII value will have the highest priority. Output ordered based on ASCII value

[@AppadiEnathandaPesureenga]

Your teaching was excellent sir, but I have doubts, sir if I use element(), peek() will I get the topmost element sir I add 4 elements by using add() like this order K, V, C, B added sir I get the element by using element() and peek() I get the element was 'B' sir... Could you please explain why and what's the reason...

[@jaspal259]

Sir, As you said, insertion order is preserved in the priority queue but it doesn't seem like this as I've tried this one & Insertion order is not getting preserved. Only sorted results will be shown in the console. Could you pls confirm once. ?

[@DheerajKumar-mb9jk]

Insertion order is not preserved . PriorityQueue return elements in ascending order.

[@gauri992]

Thankyou for the collection series sir....

[@sdetpavan]

Welcome

[@kishorep5572]

Sir which algorithm it follow internally.

[@ballaphanindra3422]

I appreciate your teaching but just came to know by seeing comments below i.e., Insertion order is not preserved in PriorityQueue.
I even cross checked, it is not preserved.
Thanks

[@onkardhavale117]

thank you sir for great teaching but i have one little doubt that sir in priority queue hertogeneous data can save in IDE 2021-12 4.22.0 version is depend on version? can please ensure that?

[@AmongUs-qt3uo]

How is insertion Order preserved in priority queue?

[@sachinsonone1823]

Please make video tree set and treemap

[@sweetthirty2]

You are the best sir please reply my mail regarding QA doubt which I have sent

[@kennyi1200]

Thanks

[@sdetpavan]

Welcome

[@srinivasraghupatruni3036]

Sir.. Queue doesn't allow duplicates then how priority queue allows duplicates?

[@jagdishs2870]

Sir.
Priority queue doesn't allow insertion order..

[@vyankateshodilwar]

Sir priorityQueue class implements Queue interface whereas LinkedList class implements deque interface which is child interface of Queue interface but you mentioned LinkedList class implements Queue interface.

[@AmongUs-qt3uo]

ArrayDqeueue implements dequeue interface. LinkedList implements Queue and LIst

[@saarza9991]

❤❤

[@snehamhetre2336]

Hi Sir, I have a question for priority queue, you said it preserves the insertion order but for me it is sorting the queue when I am trying to sys out the same. Can you please explain it?

[@gokulkrishnan291]

maximum ASCII value will have the highest priority.Output ordered based on ASCII value

[@rocked789]

priority queue will not preserve insertion order

[@abdoesam2011]

it was a mistake, priorityQueue does not preserve insertion but Linkedlist does
