[@snehilsinha4689]

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!

[@d4devotion]

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)

[@Aman-rw7rk]

[@sakshi07222]

you're really a saver either its dsa or oops or other java concepts

[@comradepeter87]

Apart from OOP just being the norm around the industry because it appeared right around the tech boom, is it really that efficient for large-scale software? It results in a lot of boilerplate, factories, builders, and unnecessary thinking required to structure hierarchies where they don't exist. Should I pass a message as a Message object or simply as a String? Maybe I might need to add on more info later so I should make it a Message, but probably not, and I would just have a shell class with a String inside till then. Forced OOP like Java's fool you into thinking you're productive, when you're just thinking about these OOP-specific problem and not getting your actual work done. Atleast that's what I think from my limited experience.

[@kalwardin3510]

Why do i feel like i have read this before?(in reddit)

[@AnujBhaiya]

Writing boilerplate code with builders, factories and OOPS concepts has several benefits: 1. Provides uniformity, makes the code more readable and maintainable 2. For already known problems, it's easier to use solutions provided by OOPS then to reinvent the wheel. 3. Modular code, easy to reuse, extend. 4. Writing Unit test cases is easier. These benefits more than compensate the cold start problem and this is the reason enterprises use OOPS in their codebase. Basically it's better to take more time and write quality code than to take spend a lot more time debugging and maintaining. I hope this answers 😊

[@comradepeter87]

@@AnujBhaiya Modular code and uniformity are not a product of OOP, but yes they were introduced to the wider programming audience by OOP. What we really wanted was namespaces, and visibility specifiers. Naked functions in a file, but inside a namespace and having the ability to be public/private most of the times fills in the required void. That's why a lot of modern non-OOP languages do exactly this.

[@comradepeter87]

@@AnujBhaiya Unit tests target a single function/method on a per-file basis anyways, so I don't think OOP helps. Any language with ability to write tests and functions can do this.

[@comradepeter87]

@@AnujBhaiya Good quality codebase in any paradigm will require less debugging and maintaining. But I'll go ahead and say that out of all poorly maintained codebases, the second worst time I've had debugging is in OOP codebases (especially the ones that just inherit for saving writing a method but there's no meaningful relations b/w the two classes), the worst being a C codebase in an embedded system. All these projects were open-source that I tried while I was still in school (just passed out recently).
