Java developers are computer software programmers using the Java language to develop computer applications, web development and meet various server and client requirements. A Java developer is primarily responsible for designing, developing, and maintaining Java-based programs. As a Java developer, you’re most likely to be a part of the IT department of an organization and work closely with one or multiple teams based on the company requirements.
Roles and Responsibilities of Java Developers
Java developers develop complex web applications, such as animated drop-down menus or sounds that get played on clicking the mouse. Java is widely used over e-commerce websites for aggregating user data and validating user information. It’s the responsibility of Java developers to utilize this scripting language for altering the design and functionality of websites as per the client's requirements. Java developers may be involved in writing programs for themselves or updating existing applications. Furthermore, they look for scope for fine-tuning and optimizing Java-based web applications. Java developers often test programs to ensure that they are on the right track. This task primarily involves solving technical issues with the help of debugging, research and investigation. Also, Java developers can be seen mentoring and providing technical guidance to junior-level professionals requiring expert-level knowledge for doing specific tasks. For a clear idea of the roles and responsibilities of a Java developer, you can consider seeking Java training in Hyderabad and seek lucrative opportunities as it being the second-largest IT hub in India.
Java Developer Skills
Here we bring the top ten skills required for becoming a Java developer:
Basic Java Skills: To be an efficient Java developer, you’ll be required to have the following skills:
Object-oriented programming (OOP): This Java skill is used for combining objects for enhancing the safety and stability of a code.
Design pattern abilities: These are coding blueprints used for resolving problems in a software development module.
Abstract classes: It is used in OOP for simplification of coding.
Serialization: It helps in converting items into byte streams that help in transporting objects between Java virtual machines.
Java build tools: Java developers use these tools for operating course code applications. A few examples of such Java build tools are:
Apache
Sonatype
Gradle
Bazel
Nexus
CMake
3. Java EE components: Java developers need to have knowledge of developing server-side applications using the technology of EE components like Java Beans, Java Server Pages, and Servlets.
4. Spring framework 5: It is used for developing Java applications using annotations. Java developers should be proficient in it given its exceptional object injection capability, elegant syntax, and simplicity.
5. Unit testing: With the growing size of the application, it becomes pretty difficult to look after its maintenance and write automated tests. This is where unit testing tools such as JUnit and TestNg are used for pacing up automation test writing by offering an easy syntax.
6. Java Virtual Machine: This abstract machine is used to load, execute, and verify code or create a runtime environment. Therefore Java developers must be efficient in running this machine.
7. Web Technologies: A Java developer must know how to use web technologies for communicating from one computer system to another utilizing markup languages such as CSS, HTML, or JQuery.
8. Advanced JavaScript frameworks: Java programmers need to know in detail about DevOps processes such as CI/CD and tools like Jenkins, Kubernetes, Docker, Chef, and Maven.
9. Machine learning or Artificial Intelligence: Knowledge of machine learning or artificial intelligence helps Java developers easily process large amounts of data.
10. Soft Skills: In addition to technical skills, Java developers need to possess soft skills like the ability to work in a team, time management, effective communication skills, and the ability to pay attention to details.
This article brought to you the top ten skills that are a must for any Java developer. Every Java developer needs to work hard to acquire these skills to have a rewarding career and manage the tasks efficiently.
