Passing immutable data between objects is one of the most common, but mundane tasks in many Java applications.
Prior to Java 14, this required the creation of a class with boilerplate fields and methods, which were susceptible to trivial mistakes and muddled intentions.
With the release of Java 14, we can now use records to remedy these problems.
In this tutorial, we’ll look at the fundamentals of records, including their purpose, generated methods, and customization techniques.
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.

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.

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.

In this video, we use the this keyword in Java to access an object’s instance variables, invoke an object’s instance methods, and return the current object. Thank you for watching and happy coding!

#keyword #java #using the this keyword in java #what is the this keyword
Static is a reserved keyword in Java. This blog will explain how we can apply a static keyword in Java to various programming aspects, including variables, blocks, methods, and nested classes.
Table of Contents
In Java, when a static member indicates that it belongs to a type itself instead of being an instance of that type. It means that only one instance of a static member is created and shared across all class instances.
The primary method of the class is generally static. The static keyword in Java is used for a constant variable or a method that is the same for all class instances. The keyword is primarily used for memory management. Learn more about Java architecture and components.
