Learn Java OOP (with code examples)

Показать описание

Learn everything about object-oriented programming in Java. This is part 2 to the world's shortest Java course that I created out of pure spite, because no Java course is complete with talking about OOP.

So here it is, an OOP course for a programming language that'll actually get you a job.

0:00 Overview
0:28 Encapsulation w/ Classes & Objects
7:53 Inheritance
12:30 Polymorphism (Runtime)
16:40 Polymorphism (Compile Time)
22:04 Abstraction (Classes & Methods)
25:06 Abstraction (Interface)
28:47 Build Something Yourself

Don't know why you'd want to follow me on other socials. I don't even post. But here you go.

Sir, I'm a java developer too, haha I love how you show the true power of this, bunch of people are triggered!! not knowing that almost all the things they are using for entertainment or utilities for the day-by-day, are written in java, like it or not!
This shows how many people are coding without clean architecture/proper modeling, I wish I could give you thumbs up twice!

This is really helpful! Many highschool curriculums such as the IB (and pretty sure AP) heavily lean towards java.

I am about to take a course on Advanced Object Oriented Programming using Java for school and am trying to get as far ahead as possible so I don't have to struggle through it like I have in the past. I've got a feeling this video is going to teach me a ton, so thanks in advance!

Very clear and concise and most importantly, enjoyable to watch. Good job

Damn your course is brilliant.
No boring, generic examples, but perfectly understandable references. Have consumed x courses and books alongside my education, but this video tops everything I've seen so far. Feel honored and thank you very much!

Your tutorial style is great for beginners and experienced alike. Clear concise, and slow enough for beginners.
That being said don't be afraid to rewind and rewatch as many times as it takes if you are just learning.
Thank you for your effort.

on the topic of OOP, i think a really cool thing would be to show the performance and power of java by doing a small little game with libgdx or something. I love java, all my backend friends love java, but every time i try learning it i get overwhelmed. my max on language complexity seems to be c#.(i use javascript, python, and c#)

Please do something like this for Android :) Love the channel btw

This is really helpful and I like your perspective on how to go about these concepts in java 😊

I want to learn java and i think it would be pretty good if u create a Udemy Java course 🙏🏿🙏🏿

the polymorphism example was just bad but i loved it, lol! another thing is i've never used interfaces, ever! maybe its because i'm still a learner but i've never found a case where i need to use it
