Learn how to not have to implement getters, setters, and other methods for your Java applications by only using a few annotations.
Developing in Java can sometimes feel a little bit verbose. As programmers, we are always eager to write more code but wanting to do less at the same time.
Coming from a C## background, when I started programming in Java, I’ve always asked myself: _How can I avoid having to write all these setters and getters? _One day I was introduced to Project Lombok.
Project Lombok is an open-source library that helps you write less code in a few areas. Just to mention a few… you can avoid having to implement:
In this article, I’ll be going over a few of these annotations to help you get a better idea of how Project Lombok might be included as part of your Java application.

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.
In this article, we will be installing OpenJDK on Centos 8.

Having another pair of eyes scan your code is always useful and helps you spot mistakes before you break production. You need not be an expert to review someone’s code. Some experience with the programming language and a review checklist should help you get started. We’ve put together a list of things you should keep in mind when you’re reviewing Java code. Read on!

According to some surveys, such as JetBrains’s great survey, Java 8 is currently the most used version of Java, despite being a 2014 release.
What you are reading is one in a series of articles titled ‘Going beyond Java 8,’ inspired by the contents of my book, Java for Aliens. These articles will guide you step-by-step through the most important features introduced to the language, starting from version 9. The aim is to make you aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.
In this article, we will talk about the most important new feature introduced with Java 10. Officially called local variable type inference, this feature is better known as the **introduction of the word **
var. Despite the complicated name, it is actually quite a simple feature to use. However, some observations need to be made before we can see the impact that the introduction of the word
var has on other pre-existing characteristics.

Everyone makes mistakes, not just beginners, but even professionals. This article goes over a dozen common mistakes that Java newbies and newcomers make and how to avoid them. Have you or your colleagues made any of these common Java mistakes early in your career?
Everyone makes mistakes, not only learners or beginners but professionals. As a programming course, the CodeGym team often collects mistakes of newbies to improve our auto validator. This time we decided to interview experienced programmers about mistakes in Java they made closer to their careers start or noticed them among their young colleagues.
We collected their answers and compiled this list of dozen popular mistakes Java beginners make. The order of errors is random and does not carry any special meaning.

If you’re looking to learn how to code in Java, you should be taking advantage of these resources. Whatever your preferred style of learning, there is something here for you.
In this tweet, I was asked if I had a list of resources for developers who are new to Java. I didn’t at the time, but I’ve spent some time researching, and here is that list.
I’ve listed content that is both free and paid. It’s not that one type is superior; it’s just to give you plenty of choices. These are the resources that I’ve used and do still use to re-learn Java. So, if you’re new to Java or looking to pick it up again after a break, this blog is for you.
The other super important point is that everyone learns differently; some like reading, some like doing, some like watching, and most of us like a bit of a mix of everything. I tend to switch between them depending on what I want to learn about and how I feel. You’re probably similar, so pick an approach that works for you.
