In this tutorial, we will walk through installing Java on Debian 9. Java is one of the most popular programming languages used to build different kinds of applications and systems. Applications developed in Java are scalable, flexible, and maintainable.
There are two different Java packages, Java Runtime Environment (JRE) and Java Development Kit (JDK). If you only want to run Java programs, then you need JRE, and if you are Java developer, then you will need JDK, which includes JRE and development/debugging tools and libraries.
There are also two different implementations of Java, OpenJDK and Oracle Java, with almost no differences between them except that Oracle Java has a few additional commercial features.
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.

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.

GIMP is a highly renown open-source image editing application that is available for cross platforms including Windows, Mac OSX, Linux, and more other operating systems. The best part of this application is, developers can change its source codes and distribute the changes to more users as well. For normal users, it offers a wide range of simple and advanced features to manipulate with any image format. Also, it can be used as an image renderer or image format converter.
Steps to install GIMP on Debian Linux versions

On March 16th, 2021, Java 16 was GA. With this new release, tons of new exciting features have been added. Check out the release notes to know more about these changes in detail. This article’s focus will be on Java Records, which got delivered with JEP 395. Records were first introduced in JDK 14 as a preview feature proposed by JEP 359, and with JDK 15, they remained in preview with JEP 384. However, with JDK 16, Records are no longer in preview.
I have picked Records because they are definitely the most favored feature added in Java 16, according to this Twitter poll by Java Champion Mala Gupta.
I also conducted a similar survey, but it was focused on features from Java 8 onwards. The results were not unexpected, as Java 8 is still widely used. Very unfortunate, though, as tons of new features and improvements are added to newer Java versions. But in terms of features, Java 8 was definitely a game-changer from a developer perspective.
So let’s discuss what the fuss is about Java Records.
