You summarized a whole one semester in just 15 minutes and I understand everything than my lecturer did. Awesome!

This is a semester? I hope that's just comedic exaggeration.

[@ifetayoali7187]

I’ve been in class for like a month and somehow you have explained everything far better than the lectures. This is the first time I’ve understood Java

[@annakoso8218]

I agree I think he made it a lil clearer I’m trying to crash course Java as well !

[@LisaCoppola]

I cannot believe how nicely you simplified three weeks of confusion for me. Thank you so much!

[@christianegbo3260]

lol so funny

[@tonyg5132]

You've explained static / not static in the most clear concise way where it finally clicked for me. This whole entire video was well said. I had low expectations when I saw 15 minutes but you really did an extremely good job.

[@iseeawindow]

Agreed. Awesome job John, really.

[@shynoobi7580]

I think this is one of the best crash course that I've watched! I have been binge watching Java videos for beginners and yours had cleared questions that I have. Thank you!

[@AdrianTregoning]

This is absolute gold. I'm doing two online courses and they haven't explained this as well. Thank you John!

[@taljones4844]

I've been coding for a bit but need Java for work for the first time, this was a really helpful introduction, thanks for the video!

[@valentin-sl2nr]

I rarely write any comments but this was really really useful. No any unnecessary information, not too prolonged with too many details that are unneeded. Just the basic things we're looking for. Huge thanks!!

[@maryp1131]

I wish we had such professors! Short explanation and exactly what is needed. Thank you!

[@taraporter8005]

Your videos are very helpful. After taking an 8 week course, this 15 minute video just explains it all so well. Great review and even helps me both recall and retain the concepts so much better than just the course by itself. I wish I had watched this when first learning Java and feeling like it true was a foriegn language I could never pick up.

[@Kira-tz1bs]

This is one of the best crash course video I've ever seen in KZbin. Keep up the good work, John!

[@yunheecho2270]

5 years ago, when I first studied Java, I had no clue and gave up after a few try. Now I find your videos, I now realise it is a quite intuitive language!! I find your examples so entertaining as well :D Thank you so much for putting so much of your effort and time in these videos

[@MarkWesley]

13:19 Your explanation of 'static' is most excellent. Thank you! Edit: I bounce back and forth between your videos and my college book by Walter Savitch. Please keep posting these great videos.

[@_joejoe_7863]

This is literally the perfect refresher for my CS class, thank you so much man

[@Naz-ei6be]

Great video. Took time off programming for a couple months and this is a great refresher.

[@banulalakwindu568]

Love this... Now I remember all forgot things about Java. Thank you.

[@64imma]

I'm a beginner programmer and I've been learning python actually for about 3 weeks now, but I am interested in learning about Java too. Gotta say compared to a simple print("Hello World") in python, the way to print hello world in java seemed way more complicated. this video helped me to have a better understanding of how python scripts work.

[@jakesegal]

I have been watching your videos recently and they are super informative. This is a very great youtube channel, and possibly the best java instructional channel out there.

[@Krakenman123]

got class in a few minutes so literally refreshing using this video, thanks!

[@nikkehtine]

Didn't expect to come across a video explaining Java of all things so concisely. You're awesome

[@norannoran2296]

The best feature of your videos is the short period of time. You help us to understand a large amount of information within minutes. Thank you!

[@Samharris-kx6fx]

For real!! I've been trying to understand this for months now. Thanks so much

[@artificialhits]

This is simply amazing. I don't know if it's just the fact that it's been about 8 years since I started my programming journey, but I don't recall any other moment where Java actually made sense to me. Just realized that I already knew pretty much everything that was talked here, just not in the right order

[@humerusdoc4189]

Great VIDEO! I'm in a boot camp and this was super helpful just to summaries a lot of things we flew through way too fast

[@dearsomeonerandom744]

Thank you so much for this! Freaking out over my AP exam and this helps a lot!

[@petoquius11]

subscribed, you literally explained in 15 min what I learned in a month in my programming class so simple and clear

[@kelleyannbart8348]

It sounds really clear to follow than listening to lectures in a lecture theatre for beginners like myself who has no basic background knowledge. Thank you.

[@jessicar5549]

Subscribed. Bro explaining it to us like we’re 5. Literally what I needed, thank you John!!

[@dshaf7]

Awesome review for me! My last Java class was 2 years ago and I haven’t touched it since. Thank you!

[@NarfiRef]

I’m in my second time through the same intro course, and this simple video has explained so much more to me than the hours of lectures and reading I’ve suffered through. Thank you.

[@johnbarbour5258]

This was really helpful in trying to brush back up on my former coding instruction! Thank you.

[@ghassanalkaraan]

Wow John, I love your videos, keep making these crash courses. Thanks

[@samsepiol3268]

I have been binging on java videos for over three weeks and I just came across this one... Instantly subscribed.. You explain things in a way NOBODY ELSE can get me to understand. Totes.

[@TheGrimPhreaker]

I start Java this week and wanted to get a head start on what I would be learning. I can see this will be fairly easy once I get used to things. Thank you!!

[@Roe124]

Man You're so good. Not just for the tutoring, but the use of language is perfect. Like you really understand the audience (some beginners) you are speaking to

[@thoughtscreate7068]

Excellent, I am a conceptual learner and this really help pull some unknowns together. Thank you!

[@aaronbarragan8339]

Oh my goodness sir, I think you have just changed my whole life as I finally understand Java. Thank You.

[@johndrowned7170]

To be honest, in my 3 years of experience, I hadn't come across a very straightforward and understandable explanation of Static vs Non-Static. Whenever people try to explain it, they tend to prioritize either time or quality, sacrificing one over the other. But in this case, you managed to provide a nice explanation without compromising on either time or quality. Great job! ( I was really struggling to explain this to a friend)

[@malamaiti2866]

You actually helped me for comp exam, best crash course i've watched. Thanks dude

[@maksh569]

Thank you for this video. I'm starting my first OOP classes next week and this helped me a lot! I'll make sure to check out your other stuff too!

[@kurs0r339]

The oop section was particularly enlightening, thank you! I'd recommend this video to people learning languages other than java as well!

You are a great teacher John. Thanks

[@hakimayoola9593]

You dissected the mountainous Java into shredds in minutes. You a life saver thank you. Please do more on all the complexities surrounding how to build an app and desktop softwares with Java. You handle it so well that you'll win the world with your approach. Thank you.❤❤

[@paulleon3343]

Exactly what I needed to refresh, it can get complicated when there are objects and parameters that are type objects. I wanted to refresh and get the concepts straight to understand my code. Thank you 😊

This was a really helpful overview to get me started, thank you! :)

wow Thanks John, I was so afraid to try Java as people use to say it's so hard. but this took away my fear. Many Thanks again.

[@ReasonableRadio]

This format is very helpful for people who have to "code switch" back and forth between another language and Java

[@paulsullivan8629]

Really excellent introduction, thanks John. This was helpful to me as someone with a basic to intermediate level of programming knowledge in general, but 0 Java knowledge. Hit on all the high points and differences from other languages.

Good Lord am I glad I found your channel!!! My class is taking Java and turning it into an ongoing lesson in torture! I expect programming to be challenging, but I was really dreading every week. You turn learning this into a session of listening to a positive and encouraging friend walk you through things! Many thanks, you've got another subscriber!
