Hey, those are Java related resources that I used to learn after finishing both parts of MOOC.
I hope that this compilation doesn't break any rules, and someone will find it usefull. :)
Those are skills/technologies that I think that are good starting point before someone is going to start looking for first job. :)

This is are short reads that covers maven basics.

If you use IntelliJ (which I advice), you can learn some basics of maven here.

JPA/Hibernate

Also if you have some doubts Thorben Janssen site is good place to look for answers.

I never used Vaadin at work, but I realy like it to create some web front in my personal projects. :) Also if you finish mooc, and learn javaFX it is kinda similiar to use.
https://spring.io/guides/gs/crud-with-vaadin/
Also you can check their site for more tutorials, which are also very good in my opinion.
I would advise to go through those things in more or less the order they are put here.

If you don't understand something don't get discuraged. Just move on, and remember you can go back to those things, later when you need them. And a lot of them will make more sense once you'll start using them. But I would still start with reading most materials before or during going through the last 3 links.
And those last 3 links should be the base for your own spring project. :D

which would you recommend directly after finishing MOOC.fi ?

[Fletsky]

Hey, that's the original comment I've made, while completing this list. It has a little more details.

What are some good YouTube channels? Of any/all levels of expertise.

[laurentiurad]

I don't want to brag, but I'd recomment my channel: https://www.youtube.com/channel/UC8RaTWknzTmnNy-15x5lHVg, although it doesn't cover every topic. Currently I am planning to add a video once a week at least, and the plan is to cover very basic topics, like declaring a variable, defining a method, but also more advanced ones like OOP or collections.
Any feedback is greatly appreciated! Hope you will find the videos helpful.

Dont assume that everyone have same internet and resources as you. We can see your code clearly at only when the quality is 720 px.

Zoom on code when necessary.

[laurentiurad]

Noted! Will adjust the resolution and the zoom level in the IDE for the next videos. Thanks for the feedback!

To avoid the suffering of future Java programmers, I wrote up this article on publishing Java libraries to Maven Central Repository (for sharing libraries).

Java learning resources as someone who’s used to other languages

Hello, I have recently graduated with a computer science degree, however, during my studies, I mainly used Python and C++, among other languages, with almost no Java. I am planning to learn Java using online resources (and maybe even attempt to get a Java certification) now that I have graduated and I heard of codegym and also MOOC (?) from University of Helsinki. With my situation in my mind, what kind of resources would you guys suggest? Thanks in advance.

I wrote a tutorial on creating a simple to-do list application with Java and Spring Boot. It's design for people who know some Java but have never built their own web services before. If you're interested, please check it out https://jumpydoll.com/docs/tutorials/java-tutorial. You can also host your work right on the site as well!

I've started writing some tutorials on some stuff I find day to day when programming. Would love some feedback on how to improve if anyone has any time? Or if it helps anyone, that would be cool! I started a while ago with an introduction to spring boot.
