How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

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.

Functional Interfaces in Java 8


Functional interface is an interface that consists of one abstract method. These interface can show only one functionality. Beyond Java 8, _lambda expressions _can be used to represent the instance of a functional interface. Functional Interfaces can contain any number of default methods. ConsumerPredicate, Function, Unary Operator, Binary Operator are some of the examples of predefined functional interfaces.

Points to remember which are allowed and which are not allowed in a functional interface:

  • In any functional interface, single abstract method is allowed.
  • In a functional interface, more than one abstract method cannot exist.
  • We can have more than one abstract method if we remove @FunctionalInterface  annotation, but that interface cannot be functional interface.

From functional interface if we remove @FunctionalInterface annotation, it must be valid. We use an annotation so that only single abstract method can be present. In functional interface we can provide implementations as the default methods inside interface.

Lambda Expression in Java 8

In this blog we will understand what is the lambda expression and why we need lambda expression and how we use lambda and about the functional interface.

What is Lambda Expression :
  • It is an anonymous function.
  • Not having name
  • No return type and no modifiers.

The PYPL Popularity of Programming Language Index maintains that Java is the second most popular programming language in the world, after Python.

Although the programming world is fast-evolving, Java has remained a constant in the programming and software development world ever since its inception. It has evolved and upgraded continually to keep pace with the changing software development needs.

Best Ways To Improve Skills In Java and Python Programming

Improving their programming skill is the concern of every JAVA or Python programmer and developer. It is often seen that a better programmer is generally a better developer. Before intruding on the development domain, it is better that you focus on your programming skills. Make your essential core skills, such as Coding, Data Structures and Algorithms, Computer Science Concepts, etc., the best you can before expanding your reach out to the development domain.

Main Focus Targets for Improvement

Brush Up Basics through Books: Basics of the programming languages are the building blocks you use for creating impressive programs and projects. They need to be as firm as possible at all times. They are also excellent sources to be referred for concepts that you may not be sure about. Most books are written by coders who define their own experiences in the books or join best online java training program. These experiences can give you a brand new outlook on certain coding concepts.

Learning Java 8: It is one of the essential skills needed for any JAVA developer. Though one can argue that many latter versions of JAVA are available now, but JAVA 8 is still the best one to train you in your core concepts before you dabble in advanced versions. There are many JAVA coders who, although experts in the basics, can’t still advance in the development field. This is due to them not being clear about the programming practical basics. This can be corrected through extensive coding through JAVA 8 to clear and solidify their concepts. JAVA Skills are now essential in all development jobs and interviews.

Learning Spring Framework: Spring Framework is just as much in demand today as JAVA and Python. It is imperative to add this skill to your repertoire. This is due to the fact the many companies today prefer that the development is done using various Spring frameworks, such as Spring MVC, Spring Boot, and Spring Cloud (When concerned with Web Application). It also helps with the promotion of concepts like Dependency Injection and helps ion the development of testable software. It is necessary for the modern-day software.

Learning Unit Testing: A good and professional code and software developer is obligated to create unit tests for their code. Their code and the unit tests devised to test them act as the true measure of their coding prowess. Today’s coding scenario is much different from earlier. There are several tools available for code and software developers today for help with unit testing, integration testing, and automation testing.

Take-up Lot of Coding Projects: They say practice makes you perfect. That is especially true for the coding world. No amount of theory will make you prepared for challenges the way coding does. Coding gives you exposure to practical problems that crop up in coding tasks. Through repeated coding, you refine your practical coding style, designs, error handling techniques, threading, and take them to their best extent you can. Rather than simply learning to code, you learn to compare outputs even before they occur.
