Learning Java is much more than just expanding your knowledge base; it can give you a much-needed boost in your career.
Even when it comes to a programming language, like Java, which requires low learning ability, there are many hidden aspects for beginners.
What mistakes should one avoid?
Let’s go through a few that you could avoid during your learning process.
The theory is good for laying the foundation, but avoid too much theory at the expense of exercise. Reading a lot of Java books won’t help you actually code programs and Android apps.
For a beginner, it is much better to solve a set of small and simple problems, along with a few more challenging ones. I’d say, a good ratio would be one difficult task for 10–20 simple tasks.
Some students don’t want to ask anything, but no question is stupid.
So, something went wrong, well, what do we do? Ask a question!
Debugging in today’s IDE is very simple.
Learn how to do it once, and you will gain a pearl of skill for your training and future work! Start debugging by the end of the first month of training, at the latest.
If you are facing a problem and do not find an answer immediately, before continuing with the code, think about what you are going to do.
Your program not only when writing the code, but also when you are developing the solution. Write down an approximate algorithm on paper.
That is very typical for self-taught students or students who are learning in a group and lag behind.
What to do in this case?
You need to understand that programming is not rocket science. Almost everyone can do this if he or she practices enough and has a sufficient amount of patience.
The most logical way to start learning Java is to start with fundamental concepts and then immediately immerse yourself into practicing them.
Studying Java programming is a step-by-step process. First, you should be clear on the basics. To simplify your work, I made a list of basic concepts of Java programming in the following sequence:
Among the various IDEs, IntelliJ IDEA and Eclipse are undoubtedly the best.
Start reading books written by experienced Java programmers and professionals. That will help you tap into the coding process, as experienced programmers do.
Put the theory that you have learned into practice. Therefore, use the knowledge you have gained and start creating simple applications (aka pet projects).
Programming as pretty much any skill can only be learned with much practice.
No one will learn to swim without actually trying it. You need an explanation, but above all, you need to get straight into the action.
Only a large amount of practice will teach you to cope with the everyday problems of programmers. For example, you will naturally create the habit of regularly checking your code and not letting issues related to it accumulate.
You will also start with the most straightforward solutions. Then move on to more sophisticated ones, continually working on improving your code.
And most importantly, you’ll get used to coding on a day to day basis.
The awesome part about it is the possibility to friend with other developers and get a job.
Nowadays, it has become one of the largest platforms that offer many online courses including a few programming languages such as Java, C++, and C.
It provides free video tutorials on how to start programming in Java. These tutorials help students learn more about Java concepts, which are much easier than other tutorials.
They also teach and guide you to work with the code in Java. Therefore, it is more of a mixture of theory and practice. You read the theory, and then you apply it.
Codewars is another online platform, which offers a ton of practice.
It’s possible to code in a browser and compare your solution with others. Each kata has a rank, and each kata is a challenge for other programmers. When you solve more complex tasks, you will receive more sophisticated tasks to improve your coding skills.
This platform differs from other platforms because it allows you to learn and practice in a group.
You are now armed and equipped with strategies and methods to help you learn Java correctly. Generally, the key to learning Java is practice and consistency.
I highly recommend that you start your journey by enrolling for an online course so that you can try it out before proceeding to the next steps of your curriculum.
