thank you

Appreciate it brother! thanks

[@jabsha8405]

Thanks buddy..❤️

[@anandjat5326]

I am learning Java by Udemy and Plural sight but your way of teaching in this OOPS concept is pretty impressive. Thanks for Sharing your Lecture here. Highly appriciated.

[@hafizaramshamushtaq673]

I'm learning java from udemy . After watching udemy videos regarding inheritance and polymorphism my concepts were vague but after watching your video my concepts became crystal clear.You are doing an awesome job man ,your way of teaching is very simple and easy . Keep making more videos .Thumbs up (y)

Delhi is still far dear😂

[@felixkimutai8478]

You're the best tutor so far, I like the way you're explaining the basics, thanks

[@pst4rock]

39:43 public static void int getCount(){ //return this.count; - don't work return Vehicle.count; // it's work }

[@timothymeagher6445]

39:43 Either of these functions work. Do not use void public static int getCount(){ return count; } public static int getCount(){ return Vehicle.count; } System.out.println(Vehicle.getCount()); //output: 1 or 2 System.out.println(Vehicle.count()); //output: 1 or 2

[@JupiiPP]

Best video about OOP I saw, very clearly explained , thx :)

[@Ujjal.0011]

You can declare the static variable in the Vehicle class like - private static int numberOfVehicles = 0; and use the method like- public static int getNumberOfVehicles() { return numberOfVehicles; } You can call the method in main() like- System.out.println(Vehicle.getNumberOfVehicles());

[@adrianb3507]

I don't what he said at 41:00, but you can certainly create a getter method for static variables, instead of returning this.count, just return count. I liked the video, mostly! =}

[@ihsandag7405]

Bro, thanks! I assure everyone so that this is the best video to understand OOP by seeing codes.

I am looking for java project u make my task very esy thanks bro.....

[@edisyldz]

I am student in a university my teacher told me many thing about OOP but it was not benefit for me like your tutorial thank you man

[@mohammadrafi2908]

you can set and get the values by going to source on the top left and clicking on generate getters and setters instead of typing it out. Select all the properties you want to have getters and setters.

[@amangoswamifitlife]

it is the best oops tutorial on the entire youtube channel

[@tikarobinson9335]

Thank you so much for making this video, I understand it so much better

[@erikageorgia5956]

The explanations is good. Need in enhancing in abstract and interface. Very insightful video.

[@Daniiel-AR]

I'm Mexican. I'm learning Programmation and I reprobated a exam. This video could save me.

[@shrangisoni8758]

This was amazing and so clear..thanks i needed this

[@zanastumasonis]

one of the best java explanations out there

[@ralphruiz2120]

My friend the way you showed these concepts was awesome, everything made sense. Sorry posting really late xD

[@ashutoshpatil26]

I have read many Articles to understand this concept but you rocked it man thnks

Thank you so much. You save my day.

[@d4r13n_9]

Great video, I learned quite a lot ..

[@torabchotu3422]

Very nice video understood almost everything...

[@igihara2662]

58:08 seem doesn' work for me.. I can't call this method back .. :( it shows error: "getLedScreen() is undefined for the type Vehicle" in main.java anyway.. i learn Java for 3 weeks now.. thanks for effort plus good work Mirza!!

Dear sir what is best way to create online ticket booking or online bank transition where is very heavy traffic comes and how to maintain synchronization and multiple thread comes.

[@soufianghalb8679]

Thank you so much, this tutorial is very clear

[@AwaisMirza1]

Glad to hear that!

[@harshaljogdand8237]

Thanks for giving this knowledge 🙏

[@uzairbinbaber6164]

thank you very much this help me a lot...

[@selvaganesh9791]

Contents are so clear but i want to know about aggregation in oop

[@sweetsisters8164]

Sir if write Vehicle2.count??then it will be reflected or not?

[@陈瀚龙]

I'm not using my ide, but shouldn't matter. I have a package oop. Inside, the public class main.java with boiler plate and Vehicle object created. I have Vehicle.java with same public fields, public constructor, BUT if I declare these files as part of the oop package, it still can't find Vehicle. If I remove it, the code compiles and runs fine. What am I missing! It only works if I don't add package oop; at the beginning.

[@avimehta5819]

Thank you so much! helped a lot

[@SalihAbi1]

That was very helpful. Thanks a lot! I appriciated.

[@markdanielbisac2320]

Sir, what is the software application that you used in this java oop?

[@sharifmusa714]

this was amazing and so clear thanks i date this

[@adrianb3507]

Also, some of the stuff towards the end is just wrong. From Oracle's Java Documentation: An abstract class is a class that is declared abstract-it may or may not include abstract methods. Abstract classes cannot be instantiated, but they can be subclassed.

[@whatsapwhatsapp662]

very true

[@susantanandaofknow6040]

i like your teaching.

[@Naturally_Aesthetics]

Now, from where can i find more questions on oop to practice...can you share some link ...

[@prateeksinghal630]

Great Video!

[@adrianb3507]

Although his speech is clear and the content is good, he misses important points about OOP. The information someone is looking to learn when they search for OOP is not here. He shows the mechanics, but does not explain the reason. For example, do you know why you use 'getters' and 'setters rather than just accessing the fields in the class directly?: He only said 'security'... Actually he can add: Allows code to be maintained and changed. The implementation details in the class can be changed, and the getter can change to accomodate this. This means the file with the main would not need any changes.

[@Ved3sten]

Ya the "security" thing is something that my professors in Data Structures also said. My only understanding is that having designated getters and setters makes code more understandable since you won't be the only person working with a specific Class or file. Look at it this way: If you had a massive program that pulled Classes from 4 different files, rather than witch hunting at trying to go through each file to change reference and member variables, getters and setters allow you to make these changes without messing something up.

[@isurumaldeniya2463]

it is better if you can add a time map

The best solution is to download the video and watch it offline no disturbance

@@abdulhafeez6355 Thank you!

[@kandarppatel3407]

Why do we use interface

[@cristianhoyos4767]

Basically just to implement a way of inversion of control that is called dependency inversion whose implementation allows us to decouple our code. That is our code depend over abstractions rather than concrete classes.

[@farmanzia8078]

nice way and impressive

the program itself is difficult making it difficult to understand.. 1 or two classes would be better..
