🙏🙏🙏 understandable to anyone. Making it simple and easy, may be this is what all professionals need. Awesome explanation. Thank you very much sir. Make more videos on important stuff like this.

[@analogylibrary]

Just to add something to the List implementation especially to ArrayList. And if we try to add element to a negative index i.e. list.add(-1,30), this will compile fine but at runtime we will get IndexOutOfBoundException.

Hi Sir ,I was just watching the "Java Collections Interview Questions and Answers" I want to know how can i download the PPT which are you displaying , purport is to make my learning comfortable

[@vutukurukrishna5016]

I like the way explaining the topics so I took u r spring boot cource on Udemy but I received different video on Udemy it's completely fraud by udemy.any suggestions on this issue.pls

[@AkanshaGrowArts]

Thanks for the awesome video

[@kirtisingh3234]

What is difference between map & hashmap

[@costinbalan251]

The Map is the interface, a HashMap is an implementation of the Map interface. you Can't write this : Map sexyMap = new Map(); but you can write this: Map sexyMap = new HashMap() Think of the definition for a Car(it has doors, wheels, a motor, etc) as the Map and the definition of the Ford Mustang Shelby gt500 as the HashMap, it is a real car not just a concept.

[@kirtisingh3234]

Costin Balan thanks

[@annomarica5413]

I checked the HashSet example with integers and it saves values in any order, while strings are being ordered . I checked it on exactly the same example as yours. Could you explain me please, what's the reason of it could be? Thank you in advance

[@harshitpandey470]

now cleared or still doubt is there?

[@shambhukadariya5821]

Nice video,Thanks a lot!

[@vimalsagar8079]

CompareTo lessthan and greather than are not returning proper valuesl. Lessthan has to return -1 and greater than has to return 1. Which is reversed in the example

[@TheRaviManikandan]

Theivame 🙏

[@dhruvkaushik7062]

HI...pls provide the java files that you are using in the videos....it will be difficult to recall otherwise...and making notes for each would take so much time....

[@ofcoursetamil8876]

nice ..but viewers don't use headphone to watch this video

[@sushantpawar5872]

i have doubt how collection interface is getting extended it shold implement in first 5 mins its like collection interface is getting extended how?

[@kuldipshah]

Interface can extend other interface

[@deepikasharma048]

It is legal because one interface can extend another interface.

[@josephkumar9112]

Thank you. Can I get the PDF..???

[@esvaramoorthyvipisanan292]

is the collection framework have Map interface?

[@SatheeshkumarNprogramming]

Map Interface is fall under collection framework in Java.. but it's not actually extended from Collection Interface.

[@SaifKhan-gl6sm]

where can i get this code

[@minhazurrahman8252]

for someone who is looking for sources: github.com/in28minutes/JavaInterviewQuestionsAndAnswers

[@abibalan3340]

Most of the time video coming as blur condition

[@infamouspy]

interface is implemented not extended

[@manvendrasingh2210]

An Interface can extends another Interface. A class can only "implement" an interface. A class only "extends" a class. Likewise, an interface can extend another interface.

[@satishkadyan1]

It can do both depends if super one is interface or class

[@tvrao123]

Please donot repeat

[@greg77389]
