Hello brother, I'd love to get on a project with you. No matter how little. I don't expect to get paid or anything.
Hoping to hear from you.
I can argue memory internal work is critical. You basically need to know how when and where to declare vars.
When we could enjoy the memory java course?
1-IntelliJ
2-Java Memory
3-Java Basics
4-Data Structures
5-Testing
3-classes,abstract classes,objects,inheritance especially interfaces
4-list,maps
Thanks
Thank you
I like the fact that you are focusing on teaching us how to become better programmers and not just how to program. Thank you for that! 🙂
That is true he is good that way-i like this guy-very personable
I totally agree. I have more then a decade of java dev behind me and through this foundations you can achieve anything. Thanks for clear explanation!
Your videos are clear, always up-to-date, and just easy to follow along, a blessing!
Exception handling might be added, multithreading also. Clean code and java code convention defenitly MUST to know
Nah, multithreading is not that important. In real world projects all that stuff is happening underground. Anyways as a newbie you won't understand it good enough to actually apply to anything meaningful. So not worth to spend your time
@@chillappreciator885 idk about that, I agree that beginners shouldn’t dive too deep into concurrency, but it absolutely helps to at least know about race conditions or know how thread pools work at a high level, most industry level applications involve some type of parallel and/or concurrent execution.
@@chillappreciator885 agree, not for beginners
I am not an english speaker (i am brasilian), but i love your videos because you pronounce the words correctly, without slang and abbreviations and it helps me to understand. thanks!! =)
I'm a Java Developer. These tech talks are awesome. Having a coffee and talking Java, literally two of my favorite things! Great video brother.
Hi sir!! i want to ask something,I'm a college student and I chose Java as the language I want to study, and I enjoy it, but my friends recommend learning other than Java because they say it's rarely used in industry? is this true? thanks in advance
@@achmadsyarif5129 This is not true. How much industry experience do your college friends have. I went to college for 4 years and have been in the industry for 3. Java has a SDK (software development kit) for almost every major technology. Here’s a short list: Adobe Experience Manager (uses Java exclusively on the backend and pays well), Salesforce, AWS (the largest cloud provider contains a large Java SDK to write lambda functions, interact with EC2 instances, S3 buckets, security groups and so on), Spring framework is a massive web framework (uses Java and pays handsomely), and the list goes on. Java is a strong language of choose for web development, mobile application development, and desktop development. If you’re interested in big data, Apache Spark has a large Java SDK which can be used for data engineering, ML and data analytics (as well as AWS). Of course, language is just a tool. Maybe Python would be better in other situations or you may need to use JavaScript. Either language or knowing all three is ideal. But if we’re just talking about Java, you cannot go wrong as is used extensively throughout industry. Java is used extensively for interviews when writing data structures and algorithms because it’s not a very hard language to learn and it’s truly object oriented. Trust me, knowing Java well can provide a great career for years to come.
@@WisomofHal I'm a little hesitant because most of my friends study web development, they learn php, laravel and so on, besides that maybe I still haven't seen the concrete form of learning java results, unlike web development.
thank you very much sir, your answer really strengthens my determination to really explore java, and it is possible to also learn other tech stacks while learning java, hopefully you are always healthy.
Thank a lot for your videos! Dont you plan create courses explaining "deep spring"? How annotations works, how beans initialize, how to inspect context, what happens when we work with AOP (aspect), how to deal with all of this, etc. Something like "Understanding Spring not for beginners"
This would be great actually. People suck at explaining this stuff lol
Absolutely! Would be a super help if you made a video on that
Amazing video as always... with important core concepts and not just teaching motivation aswell.... amazing tutor... and friend :)
I'm sooo glad I found your channel. Your information is very concise and well thought out. Thank you so much for your work. It is VERY much appreciated.
Can't wait to see the second part ^^
Thank you for everything :D
Your videos are absolutely amazing man. You focus on really important concepts, pretty much anything I come across I can find a video about it here.
I think that you are the best one I have ever listen to him about programming in general and java programming you really teaching how to be a real software developer
....just keep going
I really appreciate this video
I recently got my first job as software engineer for the minister of defense here in Seattle waghinston.
I am taking your java courses since they focused more on java , react, docker and other tool.
as junior developer , they told me to focus more on java
to be honest I really love your courses.
they are lots of things I didn't understand in JavaScript and now I really understand it in java.
Man, the content you create is amazing. thank you
1 - Intelli j and shortcuts
2 - How JVM works (Heap, Stack, String pool, Garbage Collector etc)
3 - Know the basics (Classes, Objects, Inheritance)
4 - Data structures (Most important: List and Map)
5 - Testing (Especially Unit testing and Mocking)
Asc Nelson, thanks for your clarification, and it really opens my eyes to what should I have to focus on.
Jazakallahu khayran! I am learning a lot from your tutorials and other videos. What you are doing is sadaqatul jariyah, in shaa Allah.
Brilliant content as always,with a very important concepts. Keep Going Bro 💪 Baraka Allahu Fik 🙏🌸
Great selection of concepts, but I would also add understanding the time complexity of the code is also crucial, especially working with large datasets.
Nelson with the clutch message!!! Thank you bro! I am taking this to heart to become better and grow!!
Ramadan moubarek bro :) thanks jazaka alaho khyran
شكرا جزيلا أخي جمال على مجهوداتك الرائعة.
One big problem with IntelliJ: There's a lot of legacy projects out there that are still maintained in eclipse and are not easily portable to another IDE.
in my case it's netbeans lol
I am using Eclipse for a long time. ALso Eclipse + STS. And in my opinion, for spring boot Eclipse + STS is wheey better than inteli...
Not only for legacy projects I would say... no Java IDE will ever come CLOSE to what Eclipse can offer for the developers.
Companies that work with closed source software will use it to have internal plugins (any of the big tech companies with a Java and/or C/C++ stack), and big companies that want to offer a professional environment to attract developers will use it to provide a truly immersive and evolved experience (STS).
IntelliJ is cool, yes, it's very good, it's amazing. But Eclipse is much better and is the standard when we talk about Java development.
JetBrains has other amazing tools that are the standard, but IntelliJ is certainly not one of them.
WTF are you all talking about? source code is always independent of what IDE you're using... ¯\_(ツ)_/¯
you can load up any java project in any java compatible IDE.
just dont expect IDE specific settings to be picked up by the IDE.
@@PutsOnSneakers Hate to break it to you, but that's not true in practice. In theory, yes. But in practice, you very often have weird interdependent projects and things like completely non-standard build configurations that only really get picked up by a single IDE. This is especially true in big and old codebases. I've seen that multiple times.
Hey Nelson! Thanks for your advise, I'm a software engineer, and I think the software architecture concepts are really important.. hope you can talk about someday about it! Best!
We can hardly wait for the new Java course! Keep up the good work!
So true with testing because I hate writing test but it has saved me time and discover new errors! So true
Please make more of such videos for Java. I really love your content
@Amigoscode. I would really like to see a complete tutorial on Data Structures and Algorithms using Java on your Channel. I am beginning my preparation for Software Engineering Interviews and I think a Tutorial as well as It's Implementation on a Few LeetCode Problems would be amazing. Thanks. P.S. I love all the content you put out.
Testing is not about finding bugs or making sure the code works. A test is your first user of your code.
Thinking about your tests can really help you create better and cleaner code, it puts you in the mind of the client rather than author of the code.
"Test your software, or your users will" The pragmatic programmer by David Thomas and Andrew Hunt
I agree with you on that one-unit testing id essential but few instructors do it
That's a really good way to put it
Peace unto you, too! We benefit greatly from you sharing your knowledge!
Thank you for the inspiring videos. I would also like to see a video/course on refactoring to the patterns
Muito obrigado, amigo. Espero que nos traga mais conteúdos similares.
tks for sharing, I would add generics, streams and functional !!
Os cursos são incríveis, sempre recomendo ao pessoal da universidade porém eu só consigo assistir pelo UA-cam,pois tem a opção de tradução automática. Seria legal se tivesse no website a opção.
Great video and i feel happy that i've already been working on them long time ago
That first question really hit hard!
Brilliant question! and the answer is: Never…. I've been refreshing and re-learning lots of concepts. Also excited about the GoLand and CLion Courses coming up!
That's amazing explanation about this concepts, but i don't love tests,OMG!!! Congrats!!
Thank you! I look forward your new videos about memory and use interfaces. You are cool 🙂
Gracias amigo, solo por ti me gusta java xD lo vendes muy bien!!!
Greetings from Bolivia, thanks for your amazing vídeos!
Love from Greece! Great videos!
This is a neat educational talk on Java. Thanks. I would like to learn more about the Java community as opposed to only about the technical and conceptual coding; although the latter is very important. I would point out that in most cases there are diplomatic garbage collection/disposal methods.
I learn Englesh and programming from your videos. Thank's for your work 👍
Walaikum assalam brother
Thank you so much Amigo for realising me that skipping testing is bad idea of my development part.
You have quite the talent for explaining things, brother! May Allah bless you!
Thanks mate...I would suggest next is about Interview Q/A.
Really I like you and your videos I'm always waiting for those videos, Please keep it.
can't wait for the java memory tutorials
Wow i do work with eclipse for a long time. actually it was the first IDE that I ever use
Thank you for the information 😊
Assalmu alikum I've subscribed to your channel! Great content here and Ramadan mubarak!
Thank you so much Bro, i got many insight from you, may Allah blessing you bro...🙏🙏
Waaleykum assalom brother, Maa shaa Allah, good to hear salaam in the begining of video, God bless you
Well, this video is a great improvement in title and thumbnail!!
I’m learning java now and this video came at the PERFECT time, thank you so much
Hey I’m learning java too I’m 5 months in its intense. How far in are you?
@@in-thegarden i am going to start lear ing java but i am stock on where and what kind of java to learn. Could you suggest ?
@@eltorocornal2649 I’m not sure I can advice you on that as a novice myself. Perhaps someone at a more advanced level can help here. I’m learning java 11 and 17 . 17 because it’s the latest one the last time I checked and 11 because I’m getting ready for a certification along the way.
Thank a lot for your video!
It's a great lecture. Thank you! 🥰
Can't wait for the JVM and interface video I really need it because I took 2 java courses before covid and remembered nothing
I have a question that either I don't know enough technical terms to be able to search for the solution, or I'm not phrasing it right when I search. So, maybe someone in your community can help. Class A takes object X's information and writes it to a file with a string variable from object X as the file name. It then passes it off to Class B who checks user input info against the what's on file, it sees that it's valid and passes off to Class C who apparently has amnesia. It can't find the file because it knows nothing about object X's string variable to look for said named file. I say Class A, B, and C, but they're really frames. Frame C won't open unless Frame B says it's okay. How is it that Frame B is able to read the file written out by Frame A, but Frame C can't so it just writes to an empty named file (eg: instead of file.txt, it writes to .txt)? I have it such that the file is tied to the object so that another instance of said object can't have access to it, but it can have it's own.
Thanks bro, great advises
I watched your Intellij tutorial and it made all the diference.
Gracias por este video, muy importante, muchas gracias
I love your videos. Can create a video of practical coding java? I learn java program for 3 years and I have never create a gui with java. Please could create video based on a real world application. ✌
Thank you brother for what you do 😊😊
May Allāh bless you. I'm a CS student and you're my number 1 youtube mentor
I appreciate your effort and time to build java community, Inshalla we will get there .
Please can you inclued to explain how java virtual machine works in our code?
Wa'alaykum Asalaam Akhi! Bless you for the help with these videos🤲
Better than that, How people build a mental model about Java ? I think this is really the must.
Amazing Video :) thanks ..!
walaykum salam my brother thank you so much for your efforts and ramadan mobarak!
thanks bro. This is very informative!
Sir please make a video for when to use interface and when to use abstract classes..
Wa alaikum salam brother. I really like this intro and your content is the best !
Good content,always helpful your videos,are you a Mouride ( your hat makes me think it) ?
WAS brother. Thanks for the good content.
Amigos brother, do you think I could use vscode for java and spring instead of IDEA? Why would I use/buy IDEA over vscode?
Great vid as always
Yes testing is important. Unit and integration tests are important for any project. Also too use the right tools for that specific test cases. Ive seen using mocking the calls in integration tests and I'm like 🤔🤔
An interview prep video for beginners please !
Jazak Allah khair brother mashaAllah good video.
Could you possibly do videos on some programming principles with examples? Like SOLID?
he did one, check his latest videos
I don't know what's that thing you did at the end of the video but it was funny I had to hit the like button...
Package structure. Literally file structure seems daunting to a beginner and that affects access levels and all types of other ripple affect stuff.
I'm just so used to use VS Code that it feels really hard to change for anything else ;/ (even tho Java on VS Code doesn't feel too good, tbh, with the intellisense just stopping working from time to time or the maven packages not being found sometimes too...)
i broke my femur trying to use vs code with java. But i also broke my other femur trying to learn eclipse :(
Mashallah what a great video!
Jazakom Allah Khairan
Salam brother great effort JazakAllah. When is the Bootcamp launching? super thanks
great content man
Do you think vs code is a decent IDE? I'm new to Java and using that IDE but I'm not sure if it's a good choice in the long run
Hello Amigoscode, can we expect any discount for courses during easter weekend? I am mainly looking for k8s course.
Very important question for me, can modern JavaScript eg. Nodejs …program spring framework as Java does? I searched around but find nothing.
Best as always!
Assalamualaikum, hi bro.
Please make video tutorials for simple applications (such as phonebook crud), from the development process to deployment to the production server. To get a complete picture of everything needed in making an application using java, until the application is in production. Thanks.
Waiting for your next video 🤞
As always - first like, then watch the video and not regret it in a single bit
Yes, I enjoyed your video. :)
Hi amigo, do you have a video about how different java versions evolved, what are features adding or updated?
You missed the biggest concept of all - OOP. It is the unifying technology of all the main programming languages. However, you did mention inheritance as a sub-concept.
Some, please, can we tell me: How did he named the video about lists and maps that he mentioned in this one? ?. Thanks for your videos and good teaching technique, also the greatest attitude ever.
