Top 5 Java Developer Skills that are high in demand in 2023

Table of Contents [show]

Introduction

Because of its speed and dependability, Java is one of the most widely used programming languages, and businesses of all sizes employ it in their technological stacks.Uber, Netflix, Spotify, Google, and Amazon are just a few examples of companies that employ Java. Java developers are therefore in great demand. There are numerous factors that make it one of the top five languages used by software developers today:

• Platform independence and versatility. 
• Java is used for various applications across industries, from Android apps to robotics, cloud computing, and computer games like Minecraft.

So if you are fluent in Java, you are in a great position to boost your career. There are currently thousands of open roles for developers with Java skills, but which ones will get you to the top of a recruiter's "must-have-interview" pile?

Basic knowledge of the Java language

What does a Java developer do? They create various software: from desktop and web applications to cloud and mobile applications. Java's capabilities extend to big data applications along with Python.

If you want to succeed in your career as a Java developer, consider our list of Java technologies:

• Principles of Object Oriented Programming (OOP) because Java is an OOP language.
• Relational databases such as MySQL, PostgreSQL, and MariaDB. Writing MySQL queries will also come in handy.
• Popular version control systems like Git and BitBucket.
• Employing an IDE, such as IntelliJ IDEA, for software development.
• Web interface technologies such as HTML, CSS, and JQuery.

Top 5 Java Developer Skills in 2023

1. DevOps

This is one area where I saw a lot of traction last year as more and more companies moved to DevOps and embraced continuous integration and deployment.

DevOps is vast, and you must learn many tools and principles. This is what overwhelms many developers, but don't worry. I have shared a DevOps RoadMap that you can follow to learn and master DevOps at your own speed.

If you are a skilled Java programmer who is enthusiastic about environment management, automation, and improving the overall structure, you could become a DevOps Engineer.

2. Docker and Kubernetes

You've probably heard about the buzz surrounding Docker and Kubernetes and their impact on DevOps teams. You may initially assume, "Oh, another new technology to learn," but we will emphasise that Docker is not just another technology; it actually changes the game.

Along with Kubernetes, it is one of the most important tools to learn and will stay with you throughout your career.

Today, almost all development teams—whether they work for a huge corporation or a tiny startup—use Docker and Kubernetes. It's safe to bet that if you're starting your career now, Docker will probably come up at some time.

In short, whether you're a junior Java developer or a seasoned veteran with years of experience, knowing Docker and Kubernetes is essential for your career progression and job change.

3. Microservices

Microservices are merely RESTful web service extensions with the primary objective of decomposing your code into discrete, distributed services for improved development, deployment, and management.

Microservices architecture, which emphasises elastic scaling with on-demand resources, is perfect for the public cloud. However, it necessitates thorough planning and thoughtful design.

Fortunately, Spring Boot and Spring Cloud make it easier to create microservice applications by offering shared functionality and freeing you up to concentrate on business logic by taking care of the specifics needed for cloud development.

4. Cloud (AWS)

Besides containers, the cloud is another thing that I think every software developer and data scientist should learn in 2023. Companies of all sizes and domains are now moving their environments to the cloud to save costs and have better scalability, which means that they need to work with cloud-native applications sooner or later.

Learning cloud platforms such as Amazon Web Service (AWS), Google Cloud Platform (GCP), or Microsoft Azure will put you one step ahead of your competitors in your current work and your next post. You don't have to learn them all; once you learn one, you'll have a good idea of the others.

5. Spring

It is one of the best and easy to use Java frameworks widely used in various Java projects. This lightweight open-source framework enables Java developers to build reliable and scalable enterprise applications. Aspect-Oriented Programming (AOP), Dependency Injection, Transaction Management, and many more aspects that make Spring more useful are also included. And yes, it can be considered a collection of sub-frameworks like Spring Web Flow, Spring Object-Relational Mapping (Spring ORM), etc.

What is the future of Java developers in software development?

As far as the most widely used programming language, Java is still in the lead.

A big and developed ecology and its popularity will undoubtedly keep things as they are for the foreseeable future. Java is one of the most popular programming languages, being used on more than 3 billion devices. It most likely won't disappear in a few years. Java is used to create web, mobile, and desktop applications. Java will be more receptive to emerging trends in development and user demands. With the implementation of a quick release cycle and increased reference build support, Oracle has adopted a hybrid strategy that combines stability and flexibility in a way that is unmatched. 

As they release new programmes and developments, Java developers must be ready to continuously update their knowledge and skills.

In addition, it has applications in the cloud and the AI sector, so the possibilities are comprehensive and ready for the future. The future of Java programmers is shaping up very positively and gives them real chances for a stable and well-paid job.

Conclusion

Well, these are probably the best skills a Java programmer can learn today if they want to elevate their career in 2023. You may know some of them, but trust us, these skill sets are highly trending for Java developers. Besides, you are not expected to learn each of them, all you need is to be good at some of them, and based on your taste and interest, you are good to go for a bright future!
