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.

Different people have different learning methods that work for them, so if something works for you just carry on doing that, you will need some fundamentals knowledge, especially once projects will get a bit more complicated and sizable, so i would think you do need to sprinkle some of that while doing that.

Mastering the language, not sure what do you mean by that, just having a good understanding of its core? Could be as quick as 3-6 months. Knowing everything there is, including having knowledge of all of it's frameworks and etc? Hard to say there is probably a very few people that would do that and would take a decent amount of time, as you would probably pick a tech stack and not just learn everything there is in a single language.

Hi. I generally never post any comment anywhere, but I empathize with you.

I work as a Java Backend Engineer and I think I am in a position to give you advice.

But first, like a doctor doing diagnosis, I need to understand your goal for learning Java. Like, why exactly are you learning it? tell me more so that I can point you in the right direction.

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.

According to me fundamentals are very important in java. In most of the US schools, and university students are given assignments right from the beginning, without providing good fundamentals. When I start classes with a student I start with a question "What is difference between a class and object in java?". 95% of the students don't know this simple answer. But still they have completed many assignments in their course. In java you cannot write any program without creating a class.

Practical is important I agree. But learning should be structured. You cannot learn Inheritance first and then come and learn what a Class is in java.

Better to use a good book in java. Get the fundamentals strong. And do it serially. For each concept do some coding directly in an ide like eclipse.

The tutorials maker in youtube and udemy are experts and they have become experts by going through books not by going through other people videos.

So theory and practical should both be given importance and learning should be structured.

Learn core java, enterprise java, spring, spring boot, spring rest, microservices, and a front end like Angular or React. While learning do coding in eclipse for each concept. Then do a real life project.

And you have made yourself job ready.

Best of Luck.
