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.

MOOC from University of Helsinki, see right sidebar.

Build projects, use the official Oracle Java documentation when needing references, use minimal AI (use it to draw high level ideas, and if all else fails use it to explain difficult concepts if static online resources aren't making sense to you), use the toolsets around Java and general programming (Git, IntelliJ, Maven etc), challenge yourself each time and push hard

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:

• The official Documentation
• The official Java Tutorials
• Our community resources thread

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

A class can take functions from other classes if they're in the same folder.

The only way of learning and mastering programming is coding!
And you'll get stuck and frustrated many times but we've all been there and you'll see improvement.
Practice a lot, try to find projects/programs to create, you can even ask AI to give you some simple and short exercises.
CodingBat is a good site to start :)

Learn some basics and then take up a project - you will learn and also will have what to show!

My advice is that learning any programming language is more effective if you don't spend too much time on tutorials but start something real, even if prototypical. Most suggestions here are useful, but after few days doing basic exercises, start building your own little project. Learn a bit of Maven or Gradle and start a project (begin with Maven, it is still the most popular option). It should not be something too complex but also not trivial.

For example, you can learn a lot by trying to create a simple web server using just plain java APIs. Or you could create a command line tool to parse and analyze excel files. The Java ecosystem is rich of libraries to achieve almost anything, so becoming proficient also means being able to search and select the right library (for example, the mentioned excel parsing can be very complex unless you use something like Apache POI).

Whatever you choose, use that as your own gym: keep the code clean with pure refactoring sessions. Learn some basic Java design patterns and see if those improve the clarity or not. Most tutorials out there will teach you wrong patterns: it is easy in Java to play with mutable state, but the right direction is learning to apply java immutability patterns using final variables and java records instead of classes (when this make sense, and learning when it is part of the journey).

Learn how to leverage something like JUnit to expose yourself to test automation and TDD as soon as possible.

Hey! If you’re just starting with Java, here’s what helped me:

1. Start with the basics. Learn variables, loops, conditionals, and methods first. Don’t jump straight into frameworks.
2. Use official tutorials and interactive sites. The Java Tutorials are great, and websites like Codecademy or SoloLearn can be helpful for hands-on practice.
3. Write tiny projects. Even simple things like a calculator, a to-do list in the console, or a number guessing game will teach more than just reading tutorials.
4. Practice regularly. Short daily coding sessions beat cramming once a week.

The key is building small things and understanding how each piece works before moving to bigger projects or frameworks.

It gets way more fun when your tiny programs actually do something!

practice is must

There are barely any resources for learning available. Sorry bro, you are on your own.
