Java course for beginners

Taking a Java course for beginners at a specialized study center is the best way to get started and be able to assimilate the concepts of this programming language.

But on many occasions, before undertaking a java course for beginners, many students try to learn it on their own, since there are free courses online that can serve as a good base (especially if programming techniques are already mastered) .

However, Java is more complex than it may seem initially, and by studying on your own you may acquire “vices” that are not recommended.

That is why we have decided to share some basic and common mistakes that new students often make when learning Java development , along with the solutions you can adopt to prevent them, whether you decide to train on your own or if you opt for a java course for beginners.

Mistake #1:

TyposMind you: they have nothing to do with your coding or developer skills, and yet they are one of the “dumb” mistakes that will waste your time learning. In the Java course for beginners we insist a lot on the need to be concentrated to write code . In addition, these errors, as they are subtle, can be difficult to detect.

The solution? You can choose or combine these two proposals:

1. Work with a good IDE or specific text editor for Java that marks possible errors.

2. Select very well and simplify the names of the functions or variables so that you can detect any typographical errors. And remember, Java is case sensitive!

Mistake #2: Not formatting the code

You need to make the Java code readable. Not applying formatting to your code means that it is difficult to understand and easy to make mistakes, and it will also make it difficult to maintain later.

Solution: If you do not use an IDE that automatically formats (sometimes ides are complicated to use from the beginning in learning Java) you can use a tool to “beautify” the code, such as uncrustify

Mistake #3: Not modularizing and “doing it all too long”

Although exceptions may occur, long functions are generally not a very good idea. It is necessary to learn to modularize correctly so that they are as clear and precise as possible. Each function must be able to specify and do only one thing, since this makes maintenance and debugging easier. If you follow these tips you will be guiding your steps towards good coding practices .

Solution: If your function has more than ten if’s, reconsider if you can synthesize it.
