10 Deadly Mistakes to Avoid When Learning Java

Here’s what happens when you try to learn to code the ordinary way. All of us are used to study by reading books: the thicker the book, the more knowledge you will get, right? Sorry, this is not the case for programming.

A lack of practice in coding is fatal. Just start coding. Start from the first day of your study and practice every single day. You won’t learn to box or dance by watching videos. And you won’t get confident in coding unless you make it your daily habit.

2. Endless studying without a certain goal

Some students, despite their age, simply love to learn. It’s the process, not the result they aim for. Of course, it’s always great to broaden your scope, but you will probably agree that there’s no point in wasting hundreds (if not thousands of hours) to get a trendy hobby.

In coding, even if sometimes it’s kinda tough for you, you simply love it or not. Developers, that code just to earn more money, won’t get hired to Google or other company with a big name.

Because programming is simply not their vocation. Likewise, if it’s your passion, but you’re not ready to practice every day, programming might also be not for you.

3. Trying to reach too many technologies at once

Software development is a deep ocean of data and tools. If you try to learn everything that pops up and seems interesting, you might get stuck at the beginning totally confused.

This is why you need a certain plan, that in your case should include Java Core, coding projects plus the programming tools. It will also help you avoid the risk of being a lifelong learner and set your education in a defined timeframe.

4. Making gaps in your education

Remember that “code every day” motto of learning Java? Good. Think about it every time you have a lure to skip a few days of education. Taking a break as a beginner is more dangerous than it seems.

You start a new subject and it refers to the previous background which you already don’t remember at all. Such surprising “amnesia” will constantly drag you back, so do your best to move forward without any breaks.

5. Thinking that the only thing you need to start coding is knowing Java language

A language is a tool in the hands of a skilled creator. Some might say that you need to be brilliant at math to learn to code — no, you don’t. But knowing how to write the code won’t make you a programmer, too.

Programming needs plenty of other skills: a strong logic, problem-solving, the ability to visualize the structure and sequence of processes. An experienced programmer doesn’t start to write code before thinking through the logic of the solution.

6. Getting stuck on the tough pieces of theory

Often there’s no direct correlation between the amount of time which you spend on the tasks or research and the successfulness of this action. When you learn Java, persistence is important in solving tasks or making the sense of a fresh topic.

But sometimes you need to move on to get at the heart of your problem (later). A bit of friendly advice: don’t try to memorize code or delve too deep in “how the things work” in coding.

In Java, many processes run automatically, so you can focus on the intuitive feel of programming and getting even more skilled.

7. Ignoring the importance of a readable code

When you learn to programme, your first priority is to make that code work. Here’s why beginners don’t pay much attention to the readable code with clear comments, which could be “decrypted” in the future.

Here’s what most of the experienced programmers come across. When they find their first code, they don’t feel nostalgic. They try to understand, what in the world do those lines mean and exactly were they trying to accomplish. You will learn in a due course how to write readable code, but only if you make efforts.

8. Not testing your code regularly

Sad, but true: your code won’t always work as it was intended to. Be sure to check it regularly and don’t let the subsequent errors pile up. Instead of exhausting debugging and figuring out what and when’s gone wrong, you’ll deal with the smaller amount of problems on each stage.

9. Learning Java all alone

With so many online tools and sources for successful learning, you can easily become a self-educated programmer. One thing that’s missing is real communication. Your education would be much more effective if you join the community as soon as possible.

For example, Coderanch and Stack Overflow forums have large discussion threads for Java programmers. Also, there’s an Oracle Java Community, which prompts newcomers and experienced developers to join the Java Forum and follow updates from Oracle Java bloggers. Java community at Reddit has more than 107k people.

10. Thinking there will be the day when you know everything

Listen to more experienced colleagues as a junior developer and never stop learning. Programming is a profession in a field with constant upgrades, new features, and technologies, which you need to grasp to stay a sought-after specialist.

The revealed secrets of successful Java learning

Now when you know “the demons” you may have to fight with, you’re almost ready to commence. Ok, five more minutes, my friend. Here are some practical bits of advice to “adjust” your learning.[Source]- https://medium.com/javarevisited/10-deadly-mistakes-to-avoid-when-learning-java-aead894e64f4
