So for someone who wants to start learning Java programing to become a Java software engineer.

What leaning pathway would you recommend?
What books , courses or YouTube videos would you recommend?

Any tips and suggestions would be appreciated

The learning curve is pretty steep and it would take you years to master if you aren't patient enough I would suggest you learn alternative languages like Golang or probably C# which are also quite performant, if you are, start with Java SE, [Basic language syntax, core packages like [utils, lang, streams], generics, the collection framework, lambda expressions, reflections, and annotations, file handling[io/Nio] , exception handling, multithreading, and concurrency], then just have basic understanding of the web container [ web servlets and web servers] and the MVC architecture, Object Mappers like Jackson would come in handy when developing web services, running unit tests using JUnit and Mockito, build tools such as maven or gradle, JDBC to create the persistent layer (this would be abstracted by other libraries such has Hibernate and SpringJDBC when you study further , but the rudiments are still handy ),then you can enter the world of Spring and dive into spring projects ..which can also be overwhelming, alternatively u can decide to focus on reactive services like Micronaut or Vertx

Omo speak English na 😂

Anybody wey no understand wetin the guy talk, should almost definitely not start out learning Java. Or they should be ready to buckle up to do the hard lifting required to gain mastery in the language. Self-led learning for topics that you are not to familiar with can be brutal. There's a software I use at work that I am having to learn now as its required for moving to a more senior role. I first learned about the software two years ago and it all sounded like Greek and Chinese. Two years after, I am beginning to understand the basics (actually "forced" to start understanding the "basics". Self learning is very hard

Pick another language like Python or PHP and learn

just start.
also find someone that is experienced in it that can explain things to you when you get stuck. This will speed up your learning process.

But you have to know that java is very vast

Thanks so much. really appreciate

Thanks for your suggestions but its Java I want to learn. I started out as a Python dev but I feel my calling is in JAVA lol.

I want to base fully on Java.

My advise is this, if you are in Nigeria, change career path to web programming not desktop programming.

If you want to get regular jobs, move to web programming.

Java gigs or hire are very scare .

I was actually planning on going into Mobile dev, building of APIs and AI softwares

Of serious note, I don't even know they use Java for Web 😁

What is like like building web apps or platforms with Java.

What frameworks do they use. Do you have examples of websites built with Java?

If you want to go to Android development while can't you use Kotlin instead of Java. Well, if Java is your wish I wish you success in your tech career
And i hope you have enough food at home. You can't think of writing codes with empty stomach. It hurt and difficult
An alternative source of income to buy yourself all what will sustain you on your journey learning Java.
What about Good machine that can run Android Studio without lagging or hanging?
Steady electricity nko ooooo Make NEPA no frustrates you with their useless power.

The learning path I'm currently following is this below:

For traditional programming
1. Computer science: programming with a purpose. I'll take the part 2 later on too
2. Java programming and Software engineering fundamentals specialization


For Data Structure and Algorithms
1. Algorithm Part 1. I'll take part 2 later on

For Software design and Architecture
1. Software design and Architectures specialization

All courses and specialization are from Coursera. While taking them following timetable, I also make sure I do open source contribution using Java cause learning before doing ain't better enough but learning while doing.

My aim is to be a better software engineer. Though I haven't seen better spring framework and herbinate resources yet to balance it

Please learn computational thinking. Problem solving. Programming languages are just tools.
Mastering a programming language is just time wasting. Learn how to break down a problem into steps that a computer will understand. This is called programming.
Frameworks will not teach you that. Frameworks will always break in the future.

Very true in a way, vast reading that's my step now.

reading helps. It takes time to build your problem solving skills and is the hardest part.

Hi there, seems you're a Java veteran.
I've been hearing a lot about reactive programming in Java of late – esp Quarkus with Vert.x. I haven't looked much into it myself so I was wondering, what makes them superior to SpringBoot?

I think what sets reactive libraries like quarkus, vert.x, and webflux apart, is the fact that they are nonblocking [asynchronous]. Spring boot applications use an embedded Tomcat server which spins a new thread from your thread pool on each concurrent request [Thread per request model ], The number of threads that can be spawned is finite and when they are all in a busy state, any further request would be blocked pending the completion of the other threads, creating idle time, introducing latency, memory overhead. if you are familiar with the nodejs runtime, reactive libraries employ the same approach, I think webflux and vert.x uses Netty [i don't really know about the internal workings].

Java web pages are called jsp (java servlet pages)..

Personally, it is very difficult to be a java programmer, this is only for serious and careful minded programmers.

The web part is even harder, especially connecting to JDBC and co.

Just go the route of php. It's easier, faster and better.
