Java OOP in 10 Minutes (Java Object Oriented Programming) #95

[@alexlorenlee]

If you’re new to programming but want a career in tech, I HIGHLY RECOMMEND applying to one of Springboard’s online coding bootcamps (use code ALEXLEE for $1,000 off): bit.ly/3HX970h

The music at the beginning of the video was very distracting.

thx!

2:26 Overriding, not overwriting.

For those who are confused , methods are called functions in c++

we had this and more in just one lecture

This guy teached me Java OOP in 10 min while my professor took 4 months just to confuse me.

[@terrapin-yob]

It's funny how teachers in general treat you like you are stupid and take forever to explain things that are really simple. Like, "HoW dO YoU KnOw iT Is A TrIaNgLe" or some shit when it's like, we both know why so like wtf.

[@branpod]

@@terrapin-yob understand why you know it’s a triangle is important though. Obviously you can recognize a triangle in a simple geometric situations, but in more complex situations where things don’t present themselves to you, you need to know what to look for.

[@terrapin-yob]

@@branpod I know, but I've seen questions like that in middle school when it's not anything new- it's just straight up stand alone shapes

[@branpod]

@@terrapin-yob Yeah, there's definitely times where that style of teaching is unreasonable, but as an introduction to a topic, it's often worth the little bit of extra time to get a complete understanding of why, and not just how

[@terrapin-yob]

​@@branpod Yes, but I have experience times when it was just in the middle of no where- very simple things that everyone understands if you're above the age of 12.

These “in 10 min” and “in 14 min” videos are great reviews for someone who knows some Java but took a semester off. Thanks for keeping it simple, dude.

[@michaelcdarby]

It’s been a year since I’ve had to take a programming course so this was a great refresher

[@karanpolobotu5593]

This is the greatest Java OOP tutorial of all time. You've managed to break things down in such an understandable way!!! My prof has a Ph.D from MIT, and he can't teach me this stuff!! Ur WAYYY better than him at this. Thank you so much!!

[@djuka8121]

hahaha true, mine too

[@tfh5575]

wow, this is a great overview. i have two interviews this week for software engineer positions (finishing bootcamp in 13 days) and i really felt overwhelmed reviewing so much material. this was super concise and helped clear up a couple concepts i was still having a little trouble talking about. thank you!

[@adhel-estebanriverarodrigu2234]

Bravo and kudos to you, sir Alex! I'm just starting my new semester and had to refresh OOP and learn Java at the same time, and you taught all of this under 10 minutes! I'm sharing this with my entire class. Bravo Alex! 👏

[@CrypticManu]

HAHAHA WHAT A TIMING DUDE we literally just had a lecture about OOP and I wanted to watch some of your vids to make sure I understood everything :D

[@alexlorenlee]

:D

[@michaellieberman114]

This was very concise and well explained. I learned OOP and did a lot of projects/homeworks earlier this year in a class and I always tell people "any concept, specifically in CS, is simplifiable", but school doesn't do an amazing job at concise. I had a wonderful professor for OOP but in general teachers make things more complex and drag on lessons. 2 things that would have perfected this video: 1 if you had prepared a full class with variables and functions, like a full 40 line class with edge case checking for constructors and setters. 2 split the screen between "class containing main method where objects r created" and "actual class/blueprint of object" that way people can visualize things much better. for a quick intro to OOP, this was very good. even for a review for test.

[@ArnoldPerez]

"Universities hate him for teaching one semester in 10 minutes." lol thank you so much for this!

[@angledcoathanger]

Wish I had such a tidy and quick explanation on hand when I was first learning Java. Great stuff.

[@willianvinagre3338]

holy shit dude... i always struggled trying to figure out OOP concepts but these explanations are really good! it all seems a lot easier now! thanks!

[@piggiesgosqueal8066]

Willian Vinagre same. I am coming from C++ and Java OOP was making no sense. Now I realize it is very similar just a bit different syntax.

[@jasonking1284]

Nice, a compact tutorial with no going off on a tangent for 10 minutes every 5 minutes but just stays focussed on the subject. Very good video. 👍👍👍

[@manjunathadharagond9322]

Wowowowowowowwww!!!! You're the god of OOPs tutorials🎉

What a great tutorial man, this will help me in my OOP course more than my class lectures!

[@crosskrade6658]

Thank you I am currently studying Computer Science at University and I have learned so much from this channel what my lecturers cannot seem to explain, keep it up.

[@prashanttiwari7008]

Crystal clear and easy example . Precisely on point , nothing extra .

[@Videosvoorwebsites]

I've been studying from my books for the past few days, everything was made so unclear. You just cleared everything up in 10 minutes, awesome video thanks!

[@nakadelnat3030]

you just made my life easier. God! I should be thanking youtube for this video suggestion! I am a teacher and want to teach my students java. I will add your videos on our book as reference ;)

[@SoruNoSensei]

Hey Alex, this video was very well explained. I feel like I learned a lot in a very short amount of time. Keep up the great work. I'm a new subscriber based off of this video alone.

[@titivermeesch]

I've already a few years of experience with Java but this is actually the best explanation of OOP that I ever found online.

[@pufflesrock09]

Our Java class went from basic loops straight into OOP without even mentioning what a method is, I guess it's lucky I have some experience with it already. Great video!

[@omarzidan4055]

my class is doing that rn and I got no clue wtf is happening

[@simiiv5021]

Thanks for existing ALEX. you saved me! I was never so confident in OOP and kinda mugged it up. You've made coding fun for me!

[@rittenbrake1613]

This is SUPER CLEAR ! This made everything much easy to grab !

[@Cablur]

Mate, you are so incredibly awesome 🤩 I know, I repeat my self in like every comment I leave under your videos, but this is only due I can not find any better words to describe how infinitely good you are explaining stuff! Thank you so so much for your videos ❤️‍🔥

[@leahlilyrose]

you are LITERALLY THE BEST Java teacher ever, I finally understood Arrays, now I need to know about Objects, Constructors, and Inheritance I think

[@serotonin5607]

Man... this explains my whole semester... and this video helped me more than my school. Thanks man you earned a new subscriber.

[@PlGGS]

Great video! Just want to add that getter and setter methods make getting and setting variables easier for users, because the original developer(you) is(are) able to retrieve and replace the variable in different ways depending on what the user submits as a parameter to each method. Mainly, if the original dev(you) wants(want) to make sure users don't accidentally set a variable to certain values down the line, getters and setter methods can perform checks and do much more than simply *get* and *set* the variable in question when the user calls them

[@alexdien]

Helped me understand Java for my new job in 10 minutes. Many thanks!

[@og403]

Its amazing that while im sick and not really even able to focus you still made me understand better than my professor or my 250 book

I really cannot be more thankful! You made everything so clear, thanks!

[@mattnemeth1333]

This video literally saved me from my interview. You see im more of an output guy and I have problems with definitions when interviewers asked me about definitions of something, having trouble on finding the right terms to describe it that sometime I want to "just give me a computer and ill show it to you". Thanks!

[@pengwuchen3095]

This is a very good guidance for intermediate learner, but not absolute beginner. My java professor only talks about how to use different kind of method to achieve a goal, but never tell me the concept of a class, a method, or how to relate them as a whole.
