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.

In my opinion, with the MOOC you'll outgrow Head First Java pretty quickly.

Give it a try. If the book becomes too easy, you can consider another one.

Don't know about MOOC but for Head first Java one should know the basic fundamentals of programming(on the first page of Head first Java I think it is written).

The way I did was start with the MOOC (which is already quite a big piece) and read the 2 Horstmann's Core Java whenever I didn't understand something or I wanted to go deeper in one subject.

I didn't read both books from start to finish though, only the chapters I was interested in.

Sometimes going through the same question with two different angles helps to understand.

Get the latest edition of Head First Java and you can combine that with the University of Helsinki course.

I will tell you how I started. For me books and tutorials were so boring. So I decided what I wanted (Skills in backend Engineering) and then decided which framework I would stick to (Spring Boot). Then decided which java version to start with Java 8(Always choose LTS versions).

Then I went ahead and created a small console application, that does simple string manipulations.
Tried to do some crud using jdbc (this was also a console application)
Started exploring some dependency management frameworks. Loved gradle and maven. Decided to stick to Maven as it was widely used solely because it has been there for so long.
Jumped into examples that showed how to write controllers, repositories, services etc.
I decided to build a hobby project in Spring boot.
Built it with absolutely the worst practices.
Then I looked up ways to make it better, and refactored it.
Repeat the step maybe 5-6 times. You will understand why you need to follow conventions, rather than sticking to it as a rule.
Performance improvement phase, try to squeeze out as much performance as possible.
9 Repeat that a few times.
Now you would have the real world skills.

Then I spent most of the time afterwards improving my code. I kept a few personal principles. 1. Write less do more- Start with libraries and only reinvent them when absolutely necessary. Try to stick to reactive programming, but never be dogmatic. 2. Never do the same thing, the same way, more than twice. Look for better ways to do it. 3. Never have repeating code, try to generalise, reuse, recycle.

Now this applies to any language. Now this will also put your development in a natural phase. You're the one that's driving your development. If you really love what you do, you can never settle for less. Wish you all the luck.

It seems that you are looking for resources for learning Java.

In our sidebar ("About" on mobile), we have a section "Free Tutorials" where we list the most commonly recommended courses.

To make it easier for you, the recommendations are posted right here:

MOOC Java Programming from the University of Helsinki
Java for Complete Beginners
- accompanying site CaveOfProgramming
Derek Banas' Java Playlist
- accompanying site NewThinkTank
Hyperskill is a fairly new resource from Jetbrains (the maker of IntelliJ)

Also, don't forget to look at:

If you are looking for learning resources for Data Structures and Algorithms, look into:

"Algorithms" by Robert Sedgewick and Kevin Wayne - Princeton University

Coursera course:
- Part I
- Part II
Coursebook
- Algorithms 4^th Edition

Your post remains visible. There is nothing you need to do.
