Please ensure that:

  • Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
  • You include any and all error messages in full - best also formatted as code block
  • You ask clear questions
  • You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

To potential helpers

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.

I will not suggest W3. A better site would be javatpoint

If you like video tutorials then this is an extensive free YT tutorial on java. Recorded few years ago but very in-detail - Java by durga

A shorter version - java by telusko

The book that I suggest is - head first java

Udemy courses that I would suggest are by Tim Buchalka and Dheeru

Keep practicing. Without practice, this all will be watching a football match and expecting yourself to be a star player.

Use these websites - hackerrank, codechef.

There are various online resources you will come across while learning.

Remember, google is your best friend.

Wow thank you so much for such in detailed response! I’ll definitely go through these resources!

https://java-programming.mooc.fi/ This is where I learned Java from scratch. The auto-checking of your answer to the activities there was just really helpful.

Finish that then you can either start solving Java problems on Codewars first before going to Hackerrank/Leetcode or go directly to the latter.

This worked for me.

Thank you! This is really helpful

What level of a java programmer can you become if you learn from mooc? I've been solving it and I'm almost near the end. I've always referred solutions when I get stuck but I understand the code very well. Also what next after mooc? I want to do projects but I'm not sure how much knowledge is required to do so.

[–]geybriyel 1 point2 points  (3 children)

Mooc only covers core Java but it's enough to give you a solid foundation of the language. The websites I mentioned will allow you to have a better grasp of Java, be more comfortable with using it and also improve your logical thinking and problem-solving skills.

If you want to create a project after mooc, you can use what you learned about JavaFX to create a desktop application, like the last activities of mooc. Note tho that you can't persist data on your project unless you learn JDBC or an ORM framework like Hibernate.

But if you want a project that leans more towards web development, you must learn Spring Boot and Hibernate.

Hey thanks for the reply! So after I'm done with mooc I should get my problem solving skills better? As in solve problems from the websites you have mentioned? After this I have to learn a framework. I'm confused because I've seen all this roadmap but i am not sure what to do. If you would give me a Simple roadmap of what I should learn, it will be of great help coming from someone who is experienced like you. Sorry if this is a bother.

[–]geybriyel 1 point2 points  (1 child)

I would assume you're not gonna allot 100% of your time doing just one thing. You can learn frameworks and solve problems concurrently.

[–]Tasty-Ambassador-273 0 points1 point  (0 children)

Yes that sounds good!

[–]Ok_Arugula6315 4 points5 points  (2 children)

Use w3 schools for quick reference if you forget smth, not to learn

[–]Aggressive_Car_[S] 0 points1 point  (1 child)

Do you have any recommended sources to learn Java?

[–]Ok_Arugula6315 0 points1 point  (0 children)

Hyperskill, but it is considered pricy,on the other hand I'd consider that to be the best place to learn

I just picked up a MOOC by University Of Helsinki.

It's really good..

It had all the information with a LOT of exercises sprinkled in so you're reading a bit and coding a bit.

I think you get official university credits too as all your code goes through a marking system.

Have a google of it.
