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"
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!! =)
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)
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.
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.
@@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.
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.
@@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.
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.
@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.
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!
Not to forget: Debugging in IntelliJ (remote and local), How to read Code, learn to code with a the reference doc when you implement against a new framework and don't seach hours for examples/tutorials, find a mentor, learn to concentrate on coding for about 2 x 1,5-2 hours a day without getting distracted.
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.
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.
Great selection of concepts, but I would also add understanding the time complexity of the code is also crucial, especially working with large datasets.
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!
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 very much for your videos. But I disagree with the first point, Eclipse is also an enterprise tool and companies use it. It would be interesting to have a comparison of these tools on a big project, because a lot of articles or videos compare them on personal projects. Does IntelliJ perform better than Eclipse on a big project (with a lot of Maven dependencies, a lot of classes, using Spring, etc ...) ?
Seems like a too broad somewhat uninformed statement. I recently had to switch to eclipse for a large refactoring as intellij is still plagued by a import-organizing bug that wont fix multiple files (open since 2011). Then for other things I switch to Intellij from Eclipse as it is better suited. Bad point overall imo without specific mentions of lacking functionalities.
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.
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.
I am coding in java for a decade now. Used eclipse/sts for a long time, started using intellij. It is really nice IDE but I still use Eclipse/STS along with it. Biggest drawback, you cannot open multiple projects at the same time in IDE, and I hope everyone knows that lot of time we need to load multiple projects. Intellij has lot of issues with maven, caches, memory consumptions. If you have to work with some legacy project, may God help you. I use Intellij, VSCode and Eclipse/STS together. People should try VSCode for java development too.
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...)
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.
I've been using Eclipse since version 1.0, and used IBM VisualAge for Java before that. I can use IntelliJ, but prfer Eclipse. I get too many problems with IntelliJ. Another thing I've learn't is that all the business rules of an application should be testable without any framework (e.g. Spring Boot) being present. This is where very experience software engineers live.
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?
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 🤔🤔

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

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.
An interview prep video for beginners please !
Package structure. Literally file structure seems daunting to a beginner and that affects access levels and all types of other ripple affect stuff.
Really I like you and your videos I'm always waiting for those videos, Please keep it.
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...
