The world of programming is an incredibly fast-paced and ever-evolving environment. Both the Java ecosystem and the Java community are growing and developing increasingly.

This is also true about the ways to learn Java for beginners. New tools, courses, and materials on Java programming are released every year while existing ones get improved and updated. This is great, except that this huge diversity often adds headache to the end-users of these products — people trying to learn Java coding skills from scratch.

So I decided now is a good time to make a fresh and up-to-date overview of the best platforms for learning Java. And, not to make this piece just another boring list, I’ll also be sharing tips on how to make the process of learning Java from scratch as effective and fast as possible.

All of this is first-hand knowledge and working tools. And what you need on your end to succeed is consistency in your learning and probably some sort of determination not to give up.

How to make the Java learning process effective?

Here are some recommendations that should help you along this journey.

1. Create a learning plan and code consistently

I’m beginning with the most basic recommendations, but you definitely shouldn’t underestimate their importance. These are fundamentals lying at the core of the learning process. It may sound like a cliche, but it’s much more effective to approach the whole process of learning Java as a journey rather than a destination. Create this kind of attitude, stick to it, and it will pay off.

On a more practical note, you should definitely have a learning plan. By saying ‘learning plan’, I mean consistently planning and organizing your learning process. Begin with listing down your goals — what you want to achieve at the end of the course. When this is done, you can choose a course that aligns with your objectives, as well as your pace of learning and other individual preferences.

2. Don’t just write code; read it as well

One of the fundamental recommendations to beginners that all Java experts would probably agree on is to practice as much as possible. I would go further and advise you not just to write code on a regular basis but to read it as well.

Make reading code on GitHub or StackOverflow your habit. While reading, always try to understand the code. In some cases, reading someone else’s code would inspire you to find your way to solve the problem, different from the one used in the current code. When inspiration strikes you, it is always good to write some code of your own, trying to improve a part of the program. Share your code with the community; this is a great way to receive extra motivation and contribute to your future coding portfolio while still in the process of learning.

3. Learn how to deal with being stuck in the right way

One of the most common problems that developers of any level, from total beginners to experienced senior coders, face in our lives all the time is having to deal with issues and getting stuck in the process. If you don’t know how to deal with this problem, it will make it much more difficult for you to progress, as finding solutions to problems is what developers do.

How to solve a coding problem?

So let me give you an approach, a battle strategy if you will, to slaughter those coding problems left and right.

1. First, you need to understand the condition.

1.1. If you read it a few times and still don’t understand it, go to step 2.

1.2. If you get the condition, do not rush to coding immediately. Build an approximate algorithm of the solution. Use different tools and resources:

  • Debug
  • Read the documentation
  • Move away and try again later
  • Google

1.2.1. Has an algorithm appeared?

1.2.2. If not, go to step 2.

1.2.3. If yes, start to code.

1.4 Still not working? Analyze the algorithm. Try to change it.

1.4.1 If you don’t know what to do, after all, it’s time to go to step 2.

1.4.2 If you know what to do, well, just do it.

2. Ask for help. Use developer communities and forums such as StackOverflow, Reddit, CodeGym’s forum, GitHub.

2.1. If you’ve got help, return to the point where you left the problem. If you haven’t got help, leave this task for now and try to solve another problem.

4. Work one-on-one with other developers any way you can

Another valuable aspect beginners often tend to overlook is that programming is all about collaboration. So you should seek chances to work with other developers as much as possible. Collaboration with experienced developers is the way to get knowledge and motivation from them. The feedback you are receiving from them can be truly priceless and contribute to your growth a lot.

Connect with experienced developers in online communities and forums, Reddit channels.

Specialized programming channels:

  • r/programming
  • r/learnprogramming
  • r/codetogether
  • r/programmingtools
  • r/gamedev
  • r/prograrticles
  • r/webdev
  • r/dailyprogrammer
  • r/java, r/javahelp

General software development channels:

  • Hashtag Developers
  • European Dev Explorer
  • DevOps Chat
  • StackOverflow
  • SitePoint

5. Never stop learning

Successful professional programmers never stop learning. Coding is about learning something new all the time, so I recommend you adopt this kind of attitude right from the start and teach yourself to keep learning new skills in programming while you’re still a beginner and further down the road.
