By far the best video on OOP, this is pretty much what our faculty taught us throughout a whole 4 months long semester where this guy has presented the fundamentals and building blocks of OOP for java in just an hour.
bhaiya aise hi OS, CN, DBMS, System Design ye sab ke liye b koi series nikal djiye.. basically revision series jo banda last moment dkh k chala jae interview dene
Bhaiya ap meri problem guess kar lete ho lagta h ...har time ap aisi video post karte ho jo hm 1week se sochte h ...aur ap post karte ho maja aa jata h ...bahut help milti h video se thank u
After so many years of boring explanations which other courses have ,when we see this where things are explained easily and practically ,a deep respect comes for you!!!
I disagree, only basics have been covered, this video is only for refreshing the basic OOPs concepts. Interview mein WHY & HOW poochte hain. Like HOW is run time polymorphism acheived, WHY do we need Abstract Classes, etc.
Thank-you very much, for the last three year I have been reading the defination without understanding the oops concept because no one was explaining the way you explained. Thank-you 😊
Just completed java tutorial and oops tutorial. Both exactly covered what I wanted, can you please make video on java 8?Also looking forward for DSA tutorials😍
I new these concepts before u thought. But I really wondered where are those concepts used. Especially, abstraction concept. Now it is cleared. Thank you!!!
Everyone uses the same syntax to teach but "This person is amazing the way he is explaning is directly stroing in my mind he is teaching in a layman language which is easiest for anyone to grab".
I was trying to clear OOPS concepts from last one year I tried multiple resources like books, websites, RU-vid but nothing worked and finally today this video cleared my all concepts. Thanks Anuj bhaiyya keep making quality videos.
Fantastic video sir. You cleared the OOPs concepts so easily that no else could do. I would share this video and recommend this video to the guys who are struggling in OOPs concept. Thank You
Bhaiyya I'm in 2nd year right now...But when I complete my final and get placed !! God's sake if someone asked me who is the motivation,pillar,teacher it will not be any college faculty but ANUJ KUMAR SHARMA(anuj bhaiyya)👍💯💓
Really nice video. well explained. I think order of execution of constructors, SIB and IIB is also one of the important topic asked in interviews. :) Good work btw, please keep going!! :)
Must say, the way you explain the concepts is amazing... I have completed the playlist of Java DS algo taught by you in 3 days only because I enjoyed the way you explained all concepts...Thanks a lot.. Can you please make videos on advanced java data structures for placement preparation.. It would be really very helpful !!
You started beautifully about why OOPs in any programming language. (To denote/depicts real world objects in programming we use oops concepts I mean each thing around you has some properties and behaviours for example Vehicle can have properties like name, noOfGears, noOfTyres etc and behaviour like Start, Stop, Accelerate, LightOn, LigthOf)
In last android app I was getting volley not authorised error please tell what is the problem The same problem occurred when I downloaded your source code
you have to redownload your resource file bhai i was facing same issue on volley at first i thought its some difficult issue but it was just an internet issue believe me it works .
I have one doubt. this keyword can be used to call a constructor of the respective class from being inside another constructor. What if the class contains another constructor? Like, public Person(){ count++; sysout("something"); } public Person(int age2){ . . . } public Person(int age, String name){ this(); this.name = name; this.age = age; } Since both the constructors are from same class, this keyword calls first person constructor from third person constructor (i.e which is with arguments). My question is what if the class contains another constructor. Now using this() keyword which constructor will be called??
Best OOPS concepts video ever, not just for Java but for any language in general ! I have a C++ background and this video helped me learn OOPS for Java and C++ as well ! Key Learnings-> 1. Runtime polymorphism - happens at runtime because the program goes in an upward heirarchy to find the method. 2. Abstract class - Needed because the parent class might be just a concept in its own and making an object of it might not make sense! [Awesome explanation]! 3. Interface - methods are by default public abstract. 4. Abs Class vs Interface - Can't define methods in interfaces whereas can in abstract class. - Abs class -> extends interface -> implements. Thanks!
Sir honestly speaking i understood till 18.20 min. Then you just used static keyword out of nowhere. I was thinking about why you used it and how ? Afterthat i was unable to get the things that you were saying.. and sir we all love you , we all watch your videos . You don't need to be so fast toh end up entire topic of oops in 1 hr. You can take more time for that. And please take time , and be a little slow when you explain things to us.. especially imp. ones. It's a humble request. ❤️
