I can argue memory internal work is critical. You basically need to know how when and where to declare vars.

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!
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"

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
@WisomofHal

@@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.
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
Great selection of concepts, but I would also add understanding the time complexity of the code is also crucial, especially working with large datasets.
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
Jazakallahu khayran! I am learning a lot from your tutorials and other videos. What you are doing is sadaqatul jariyah, in shaa Allah.
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.
Brilliant content as always,with a very important concepts. Keep Going Bro 💪 Baraka Allahu Fik 🙏🌸
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!
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.
Nelson with the clutch message!!! Thank you bro! I am taking this to heart to become better and grow!!
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.

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.
@lukasjacobs2358

@@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.
Asc Nelson, thanks for your clarification, and it really opens my eyes to what should I have to focus on.
@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.
Man, the content you create is amazing. thank you
Muito obrigado, amigo. Espero que nos traga mais conteúdos similares.
We can hardly wait for the new Java course! Keep up the good work!
Thank you for the inspiring videos. I would also like to see a video/course on refactoring to the patterns
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.

Please make more of such videos for Java. I really love your content
Great video and i feel happy that i've already been working on them long time ago
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!
So true with testing because I hate writing test but it has saved me time and discover new errors! So true
Peace unto you, too! We benefit greatly from you sharing your knowledge!
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!
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)
Ramadan moubarek bro :) thanks jazaka alaho khyran
That's amazing explanation about this concepts, but i don't love tests,OMG!!! Congrats!!
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 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.
Walaikum assalam brother Thank you so much Amigo for realising me that skipping testing is bad idea of my development part.
It's a great lecture. Thank you! 🥰

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 🤔🤔
That first question really hit hard!

Assalamalekoum, can we have a video about lambda, like all the add methode and tool we have in Java 11 since Java 6 ?
Thanks bro, great advises
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.
tks for sharing, I would add generics, streams and functional !!
Better than that, How people build a mental model about Java ? I think this is really the must.
can't wait for the java memory tutorials

Package structure. Literally file structure seems daunting to a beginner and that affects access levels and all types of other ripple affect stuff.
