[@bates950]

Awesome video, Alex. Thank you! Please what is the title of the background song in the beginning of the video?

[@Randomlolstudios]

I think I learned more about constructors in this tutorial than the last few weeks of my cs course in college, thank you for making it.

[@Dennou85]

I have to agree, I felt exactly the same way.

[@jeremydutton193]

Ditto

[@kplwijkpl6273]

I agree , he just made a rhetorical explanation - My feeling is that he himself is struggling with this concept ~

[@RitaTheCuteFox]

I disagree, this is completely WRONG. EVERYTHING is fucking STATIC.... this has nothing to do with objects or constructors.. the constructor in this video is completely unneccesary. He didn't mention the "this" keyword and didn't even manage to encapsulate the class. Yeah you may think you understand this. Because it's completely wrong. If you use constructors and classes like this then enjoy your F in your college cs course.

[@VivianHuangSnowy]

Your way of teaching is so stress-relieving and easy to understand :') Thank you so much

[@jonathanphillips5915]

Big facts 🔥

[@thaminduKavinda]

Yeah, that's true

[@saswataroy1699]

Yeah when I see his tutorials it seems like a friend is teaching to me which helps me to understand the topics in better and easy way...

[@iliasi.4004]

not when u put it on double-speed

[@bardock7885]

Bruh did you even subscribe

[@suyogb7325]

4 java books and multiple online courses on java, yet whenever I have a java doubt I re-watch your video. Thank You.

[@AN-nk5yl]

Univeristies are missing out by not having you as a professor.

[@jordanbrown2173]

Honestly might cry, I've been completely lost in this course over the past few weeks and finally am starting to understand it thanks to these videos. Thank you

[@TheStewie96]

If my prof would explain it like you do, my life would be way more easy and I wouldnt waste so much time. Im so glad Ive found your channel. Love you

[@cosminionut5521]

Hello! I recently discovered you but it seems pretty straight forward and to the point the way you teach. Hope you won't stop doing tutorials because for small students who struggle to learn extra stuff beside school is really helpfull.

[@tressaortiz2078]

I always read my notes, read the book, then I go on KZbin and type in the subject + "Alex Lee". So thankful for the way you explain things that professors and books tend to miss the mark on

[@mantub1901]

Your simplicity in teaching, amazing man!! Concept grips with the examples make more interesting and understand in-depth, and a person learning won't forget!

[@tobbykem8241]

I love the way you explain each concepts with the recap at the end. Your videos is more helpful in my study in Java programming.

[@khakramsidiqi9731]

I love the way you teach java concepts and mix them with practical coding, it is more fun! keep up great work, bro!

[@AbhinavKumar-dr4ef]

You teach from the basics and how to think like a beginner. Awesome. Thank you.

[@13guile]

3:10 you can just type "sout" then press tab. You're welcome guys

[@13guile]

that hotkey is for NetBeans IDE, im sorry

[@manuelramos1912]

Thank you!! it worked with my NetBeans IDE.

[@bubboydarker9030]

in eclipse: type "sout" then press ctrl + space

[@Srk_Cambodia]

eclipse : you can try "sysout" then press (ctrl+space).

[@awhr0350]

your positive and encouraging way of explaining things is a relief from the monotonous and depressing type of education I receive at university. Thanks alot!

[@email677]

I like how he explains. I had never understood the Java „constructor“ topic until I‘ve seen Alexs video tutorial.

[@awesomezebra]

My instructor chose to use your videos for our class, and I see why, this was so easy to follow, thank you so much!!

[@generalzt2886]

I love how you explained this I have a final tomorrow and this was really helpful. The best part is how I also use eclipse to write code so all these tips are super nice.

[@alexisforbes3322]

Eye-opening!!!!! Thank you so much!!! Your explanation on constructors, passing parameters and giving it a reason behind it just makes your way of teaching, best!

[@davidmelbye949]

Literally better than my lessons in college. Bravo! Can't thank you enough!

[@StreakyFly]

Great tutorial! In 15 minutes I learnt more than what I did in 150 minutes in university.

[@TheChaosRainbow]

This has been the simplest and most thorough lesson I have ever come across. Thank you for sharing and being amazing :')

[@shubhamb2547]

Such a mild and relaxed way of explanation you got there, your videos are always a great help whenever i have a doubt. Thank you sooo much Alex!!

[@carolinaheredia7926]

I've been stuck on this for the past week in class! thank you so much!

[@YouSoRusso]

This was awesome dude. Thanks 👍 Semaphores, Concurrency, Multithreading would be some useful lessons but whatever you do I'll be a new student for some revision. Keep it up bro. Love the peaceful vibe.

[@linuxworld3686]

Man, I can't image I am learning 2 hours lectures in 10 minutes. WOW keep the good work.

[@Aleksei_Zukovski]

I have strated to learn Java and i have my first test on the 27th of octobre. I always watch your videos to really understand what i have to do. Thank you really much from the Netherlands!!

[@ilejovcevski79]

P.S. For anyone still experimenting with constructors, once you make your own custom constructor that takes parameters, but you still want to use the default constructor for the same class for some reason, you MUST make the default (empty constructor) as well. Otherwise it will no longer be available, and you' ll always have to enter custom parameters when you create objects of that class.

[@wesldf]

Equal Alex made on the video, got it. Thanks for calling attention for this.

[@ilejovcevski79]

@@wesldf my pleasure mate!

[@jcferreras]

Every time that I don't understand any tutorial from the web, I always go to this channel and everything seems easy to understand now. Thank you!

[@theedxqboi]

Thank you for your videos. I'm still learning Java, and these videos have been much food for thought!

[@jettsenweber6944]

thank you for breaking it down as simple as possible...subscribed

[@tomino133]

I'm switching teams at work from Web (React + Node) to Cloud (Java) and your channel has been helping me a ton so...thanks man!

[@Murga_Mutton]

More than the teaching, your videos are calm and ASMR like. It soothes my nerves when I watch the video.

[@dworuch1]

Very straightforward and informing. I follow easily! Thanks!

[@TheBaldr]

Brilliant, this totally made more sense than 2 chapters and 2 lectures I've taken.

[@leonardpcs08]

Your videos are great. I'm re-learning Java now and these videos make it possible. I joined Code with Mosh's Java course -- and when I need another explanation to his topics , I turn to your videos and they compliment really well, and I suggest everyone to do the same. Thank you, Alex!

[@peterrock5560]

i'm new to java and tbh you help me soooo much with your videos! Thank you man , hope you're good and everything is going great!

[@dav_queue]

Shout out to your channel and videos. You do a good job simplifying the explanation of all these Java concepts. Definitely a big help. Keep up the good work man!

[@xx_sanch_xx]

I just want to say thank you for making easy to follow content I learned more from watching your videos than I have all semester from a paid instructor!

[@Josip9888]

Thank you Alex for all this tutorials you share. They are very helpfull and intertaining.

[@susanajimenez4599]

I discovered Alex, a few weeks ago. Oh boy, you do know how to explain! Loved the content, definitely not the regular teacher 😀 Thanks, thanks!

[@Unlucky13ification]

I like how you explained the concepts without using all the Java terms that I heard in other tutorials. Like how you said that a constructor creates objects. Or that a constructor is a method. That stuff is easy for me to comprehend.

[@emanuelalecsa8407]

thanks, man! The way you explain is so smooth and down to Earth! Keep it up!

[@alexlorenlee]

Thank you :) I will!

[@Blarnix]

I can't tell you how amazing you are for this. You're probably the only reason I might pass this class.

[@yaturkeyneck7130]

THANK YOU! This really answered a lot of questions for me.

[@drs356]

Extremely clear and succinct. Well done and thank you for the great video!

[@kenaida22]

The way you explanation this really improved my way of viewing the constructor object.

[@jakobdonathellmann7192]

Thank you! Learning Java through you now every day :)

[@hundimbuero]

You're saving my CS first year course which I dropped, I wish I found you earlier.

[@leev9406]

very easy to understand thank you i was looking for the answer as to why we need it

[@oyskateboard5355]

Omg bro, I love you and your amazing analogy and voice. I love how you explain and explore everything simplistically. You just saved me from a semester of failure!

[@vishy]

Awesome tutorial as always!! Thanks

[@potatoostudies2881]

This Java Tutorial is easy to understand than other tutorials in yt haha. Thank you so much!

[@kevinsuriel8935]

So far best video for people on the internet. Could of saved me a lot of time back in college, just here to refresh my memory.

[@DONTKNOW602]

Thank you for this .this helps so much simplifying words used in my texts, especially since its 100 online classes.

[@lukemalonis8533]

You should be proud man, I watched about 30 different videos on this, and this video is what finally made me understand 😂.

[@richardofredemption]

Thank you for this life saving video Alex.

[@imunoriginal382]

People really need to know about you. You explained it well in the simplest way using real life objects. I'm also in need of learning implementation of linkedlist using classes, so if possible I'm eager to learn it more from you because my professor is using words we've never heard of :D

[@akhileshkumbar4864]

Really helpful, thanks for making this video

[@shern7865]

My lecturer took 4hours to explain this but you made me understand this completely in 12mins..

[@zacho9670]

Thank you so much for this and all your videos. Extremely helpful.

[@MRHashesha]

I was struggling with understanding Constructors until I watched this video :) , Thanks a lot for your explanation :)

[@emmanuelasirifi352]

I love how you walk through an example of each concept and not just spit definitions at us. Appreciate you posting these videos, makes learning java and coding much easier and less stressful.

[@CosmonautCoding]

I spent 3 hours reading Java notes and got nowhere. Watched this video twice and suddenly it all makes sense. Thank you!

[@theophilus33]

Incredibly helpful, college professor's explanation made no sense but this was very clear and easy to follow. Thank you!
