Technology evolution is here, there, and everywhere. It wouldn’t be incorrect to say that Java is also continuously evolving. Its been fifteen fruitful years that we have seen Java programming language progressing and advancing at an unprecedented speed. In research by Statista, it has been proved that Java ranks among the top 5 languages and has been helping enterprises to accomplish their business goals. Equally, as there are companies who are looking to hire Java developers or companies for their business.
Therefore, we see a lot of developers pursuing a career as Java developers. Companies can gain a competitive advantage if they want to pace up with a current market. Undoubtedly, there is a multitude of java developers and freelancers transcending in the same league. On the other hand, a leading company like TatvaSoft excels in developing cutting-edge Java applications.
So to make the decision-making process easier for companies and for developers to know what should they possess. In our new blog post, we’ll share eight Java developer skills your business needs to hire java developers and every demanded professional must-have.

1. Skills Required for Java Developers
The potential of Java has been the talk of many companies. For the fact, Java has been in use in almost every company, whether they be small companies or big tech giant companies like Google, Amazon, etc. On the other hand, there are many other companies that are looking to hire Java developers for their business. But since not many know how to hire. Let us start with the basic skills.
1.1 Basic Java Skills
The basic needs of Java mean the basic understanding of how Java works. What are the frameworks involved and what type of tools are used and finally what exactly does a Java programmer do? It may quite interest you to know that any business can leverage the benefits of outsourcing Java services. All they require to do is choose the right team of Java developers.
Java is a versatile, resilient, and all-rounding development language that helps to create a wide range of software, including desktop and web applications, cloud services, and mobile apps. Along with Python, Java’s capabilities extend to Big Data Applications. These are the skills every java developer should have
Consider the following Java technologies if you wish to excel as a Java developer:
- Java is an OOP language, it follows object-oriented programming (OOP) principles.
- MySQL, PostgreSQL, and MariaDB are relational databases. Writing using MySQL queries.
- Git and BitBucket are two popular version control systems.
- Using IntelliJ IDEA as an integrated development environment (IDE).
- HTML, CSS, and JQuery are examples of web frontend technologies.
1.2 Java Build Language, Tools, and Frameworks
When you are completely drowning in Java, there are few things that your developers must know about Java. In Java there is Java SE and Java EE, these are the two types of framework where your developers need to have expertise. Also, there are other tools and technology framework that is making a difference. Like Spring frameworks such as Spring Boot, Spring MVC, and Spring Cloud for developing web applications. And there is Hibernate framework too which is another popular framework used for projects that also helps you establish popular domain frameworks. Other than these frameworks, tour business should also understand about
- JavaServer pages (JSP) and servlets.
- Web frameworks (e.g., Struts and Spring)
- Service-oriented architecture/web services (SOAP/REST)
- Markup languages like XML and JSON.
- Object-oriented programming (OOP) concepts and patterns.
With all the basic understanding and features, we now know what Java- as a popular programming language is capable to offer. It is ideally fit for all types of development platforms. Enterprise can also use it for cross-platform app development and customized enterprise solution. In the next section, we will see what are the version controlling with Java.
1.3 Version Control
Although you might have developed something fantastic, but wouldn’t suffice to current market trends then the agenda of development is failed. Having version control as an ability would allow you to keep track of and control any modifications to your source code, ensuring that the original code is not harmed. Also, in the process of developing if something went wrong along the way and you had to start again.
The version control here is important for Java developers to be aware of all technology changes occurring in each technology and checking what makes a difference and how. As each version would demand to enhance their skills and knowledge to imply it in the current application.
1.4 Android + Kotlin
Often when you develop applications for the Android or iOS platform, It is equally essential for Java developers to have the skills required for the app development process. The required skills will help developers in the web development process. And in favor, it will help developers to create smartphone applications. Knowing how to build Android apps in Kotlin would make you stand out from the crowd.
In reality, the Android platform is gradually migrating to Kotlin, a modified Java language. Hence the Java developer must have the expertise of both Android and Kotlin to understand the engineering of the developing application.
1.5 Unit Testing
This is an area where there is a lot to learn. If you devote some time to improving your unit testing skills, then not only will your coding skills improve, but you will also become a more professional developer, which is something that every employer seeks.
Unit testing has numerous Mockito and PowerMock for mocking objects, Robot Framework and Cucumber for automated integration tests, and of course the new and dazzling JUnit 5 library are just a few of the new frameworks and tools available for Java programmers to unit test and integration test their applications.
1.6 Spring Framework5
Spring Framework is one of the popular names in Java development technology. There are researchers who say that more than 2000 websites are build using Spring framework. You basically generate objects of the classes, call the methods, and get the desired result when you use a library.
Spring makes an effort to avoid close connectivity (when classes explicitly focus on other classes and interfaces in the framework) by relying on annotations. It is currently built on the Model-View-Controller (MVC) architecture, which divides processes, sectors, and representations. Spring is popular among developers because of its excellent object injection capability, elegant syntax, accessibility, automation testing tools such as Junit 5, and low entry barrier that works well for new developers of Java.
1.7 React or Angular
1.8 DevOps Technology
As more companies move toward DevOps and implement continuous integration and deployment, this is one area where there is a lot of traction. DevOps is large, and you’ll need to master a lot of tools and techniques, which can be overwhelming for some engineers. Here are some of the reasons together with a DevOps.
Continuous integration (CI), continuous deployment (CD), and Jenkins’ position in all phases are all important concepts for a competent developer to understand.You can use it to learn and master DevOps on your own time. There are experienced Java developers who understand the technology in depth simultaneously and imply it within their business. Development and operations go hand in hand in DevOps. It will automate the overall process, structure and you can become a DevOps engineer.
Microservices is a new addition to this list. It is a RESTful web server extension, this is integrated into the application with the goal of breaking up your code into a lightweight, dispersed, and autonomous application. This allows easier creation, deployment, and management of new features with security.
With its emphasis on elastic scaling and on-demand infrastructure, the Microservices model is perfect for the public cloud. It does, however, necessitate careful planning and extensive preparation. The spring-based tools support the job of microservices by enabling simpler extraction from cloud-based applications. The features get more enhanced and improved.
2. Is Outsourcing a Good Option or Utilize In-House Java Developer Skills?
Ideally, if this shouldn’t be your question. Because there is hardly any company you don’t look to hire java developers. Java is a valuable skill to master, and the best thing is that the internet provides some of the best tools for learning Java, from the fundamentals to advanced programming. The learning from the Java development process will boost the overall performance of the application. We can address all the requirements and fulfill them with Java.
