You summarized a whole one semester in just 15 minutes and I understand everything than my lecturer did. Awesome!
Are you cs student
@@basavanagowdaraju8815 no :)
@@basavanagowdaraju8815 yes
Your lecturer should be fired asap
This is a semester? I hope that's just comedic exaggeration.
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
I agree I think he made it a lil clearer I’m trying to crash course Java as well !
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.
Agreed. Awesome job John, really.
I cannot believe how nicely you simplified three weeks of confusion for me. Thank you so much!
lol so funny
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!
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!
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.
This is absolute gold. I'm doing two online courses and they haven't explained this as well. Thank you John!
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!!
I wish we had such professors! Short explanation and exactly what is needed. Thank you!
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.
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
This is one of the best crash course video I've ever seen in TH-cam. Keep up the good work, John!
Subscribed.
Bro explaining it to us like we’re 5. Literally what I needed, thank you John!!
subscribed, you literally explained in 15 min what I learned in a month in my programming class so simple and clear
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.
For real!! I've been trying to understand this for months now.
Thanks so much
This is so good, thank you. Just started my course and its really helped me connect the dots.
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!!
Didn't expect to come across a video explaining Java of all things so concisely. You're awesome
Great video. Took time off programming for a couple months and this is a great refresher.
Love this... Now I remember all forgot things about Java. Thank you.
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.
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.
This is literally the perfect refresher for my CS class, thank you so much man
got class in a few minutes so literally refreshing using this video, thanks!
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.
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
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!
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
Awesome review for me! My last Java class was 2 years ago and I haven’t touched it since. Thank you!
Thank you so much for this! Freaking out over my AP exam and this helps a lot!
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
omg thank u so much, i've been strugling with my college, i do love studying but i have some family issues and working alone in a massive comic (story and drawings by me) so having a instructive channel like this that doenst have much "filler" is amazing (since i dont have a lotta time)
This was really helpful in trying to brush back up on my former coding instruction! Thank you.
Great thanks! I love the speed at which you speak, because it goes at the same speed as my mind (regarding this topic)!
Oh my goodness sir, I think you have just changed my whole life as I finally understand Java. Thank You.
The oop section was particularly enlightening, thank you! I'd recommend this video to people learning languages other than java as well!
I probably got more information on this video than in my whole study week!!! You are nice, mate!
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!
Where were you these many days ,finally found the best channel for java bigginers your awesome john👏👏
Excellent, I am a conceptual learner and this really help pull some unknowns together. Thank you!
Oh God! I've watched the whole video and understood every single thing he explained for 15 mins straight. You did a wonderful work. Thank you sir!!
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.
You actually helped me for comp exam, best crash course i've watched. Thanks dude
Thank you so much for making this video! You make what is complex - easy!
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.
What a nice video. Preety summarized, very intuitive, simple to understans. Learned a lot of basics wathcing this.
Congratz.... you earned a new viewer lol!
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.❤❤
greatest crash course clearing all the doubts that I had moving from javascript to java
WOW!!! This is pure gold. PURE GOLD. I just discovered you. You are sharing PURE GOLD with the world. Thank YOU!!!
You are a hero for explaining that static stuff. Like a hero
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! :)
Many thanks and very happy please I nned to watch more of your video since I having difficulties in programming.
Thanks
I can't believe that you finished my entire semester in 15 minutes 😯. I finally understand this . Thank you
Bro thank you so much 😭 never knew Java could be taught like this very simple and easy to understand (why doesn't this video have million views why??)
This was a great repetition for me ! I don't even thing I understood these as well the first time I took a course.
Thank you a lot!
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)
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!
Thank you for the "static" keyword explanation. Just awesome. :D
This is hands down the best Java video on TH-cam. Thank you thank you thank you!
Wow John, I love your videos, keep making these crash courses. Thanks
I haven't seen Java in years...this video helped refresh everything I learned in 2 years!
Thanks for your work, John! Well done!
This video intro actually grasped what I needed. Some comfort from everyone else seems like they get everything done so quickly in terms of coding and I'm the only one falling behind and still wondering what a String is.
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.
This is the best Java in one video for beginners!! Thank you for making it for everyone!
Best Tutorial ever.. started learning java today with hardly any coding experience will update month by month of where i stand. ! GoodLuck Guys!
Thank you. Great guide in simple words
this was a really great video for helping me begin to understand static and not static
This is the best tutorial ive seen everything is way easy to understand thank you
This is amazing and so clear and easy to understand!! What is this wizardry 🤯
Incredible content! Strong communication is hard to come by and you have it in spades!
Thanks sir i have been struggling with these basic concepts. after watching your video its all clear . very thank u
Thank you so much, I can comprehend on Java and it makes so much scence
I needed a course refresher thank you very much!
This was all I need, thanks!
You are a great teacher John. Thanks
Wonderful video! I'm looking forward to exploring more of your channel.
what an amazing teacher wow ! Honestly loved this you got yourself a follow
Thanks alot for your videos it's been helping me through school. This was a great refresher. I had to take off school due to medical reasons but I'm going back soon and needed a refresher. 6 months left and done with software dev.
I have a Java test this Monday and yesterday I broke down and cried myself to sleep because I was so frustrated and confused with my lectures, now things seem way, way simpler for me. I understood in 15 minutes what I have tried to understand a whole semester. Thank you thank you thank you!
Good luck on your test, just keep coding and practicing!
I absolutely love this video! Thanks for it!
Please make more videos like this and try to speak slowly. It`s a lot of new information (for me) and it`s hard to follow.
thx for that static explanation, i was needing that 🤧😀🙂
this knowledge is enough to dash a interview if people has knowledge on other languages before ,nice work
This format is very helpful for people who have to "code switch" back and forth between another language and Java
Great video! going for the java gig these days, and this really helped!
i love how u explained the Cat Class, the concept is what im struggling with most
Thanks a lot you explained in a way more understandable and digestible manner than my professor, I was having a lot of trouble but this explained it a way I actually understood
👍👍 Great tutorial and great way to introduce things. Thanks so much John!
I needed a java refresher before diving into Algorithms 1 course by princeton. This video is perfect.
Thanks for the "static" explanation at the end 👍
I congratulate because your video is great for the startup with Java. Keep publishing.
thank you for this, finally understand Java, the best crash course ever.
I love this so much I'v been looking at tons of videos and yours are def the best ones
This helped a lot thank you!
I am very grateful for this video, because Im not very good in english and your explanation made me understand a really complex thing in a simple way. Thank you very much!!
This was so helpful! I’m in week 3 of class and feel like I haven’t even started yet. I literally just signed up for a tutor, but wanted to find YT video to help in the meantime. You definitely made some of it make sense…like I get the feel of what is actually going on now. Versus looking at a bunch of codes just doing what I can to follow along. I was like why I am even writing this, why does it have to go here, what is one line doing for the other, etc.. I was feeling like I needed an “Intro to Introduction to Java” class 🤣.
Thanks for the video. Coming from python this video very quickly helped me understand all the (seemingly) gibberish syntax in the java language.
