Backend Developer Skills in Java Definition, Languages & Examples
Backend Developer Skills collectively empower a backend developer with the ability to develop robust web applications that scale. But do you want to read more about this? It is time for Backend developer skills in Java.
Have you ever wondered what it takes to become a perfect backend developer? Though coding and technical skills are essential, soft skills are also necessary.
These hidden powerhouses operate in the background to generate the many different experiences you can enjoy daily on the Internet.
Good backend developer skills in Java include how to architect robust applications and databases and how to work with front-end engineers and product managers to help create digital solutions that could solve actual problems for their users.
So, what are we referring to here regarding backend developer skills? Let’s learn about it.
Backend Java Development Skills in Java
The skills of a backend developer who works with Java include the development of server-side applications effectively.
Here is an in-depth overview of the essential skills for a Java backend developer:
1) Java Programming
A core requirement for a backend developer is a good understanding of the Java programming language.
They must be well-versed in core Java concepts, including data types, control structures, exception handling, and multithreading.
2) Spring Framework
The Spring Framework is the whole framework for Java Development. To build enterprise-level applications, backend developers need knowledge of Spring Core, Model-View-Controller, Spring MVC, and Spring Boot.
3) Hibernate
Hibernate is the OR Mapping (ORM) toolkit for Java. It represents the interaction with databases by mapping Java objects to table-based databases.
To manipulate databases effectively, backend developers must have expertise in Hibernate.
4) Web Technologies (Servlets and JSP)
Servlets and JavaServer Pages (JSP) are key technologies used in building dynamic web applications in Java.
A backend developer should know how to handle HTTP requests and generate dynamic web content.
5) RESTful Web Services
Knowing how to create RESTful APIs is essential with the increasing requirement for scalable and interoperable web services.
Backend developers should be good at designing and implementing RESTful services using Spring REST frameworks.
6) Database Management
Database working skill: All backend developers must know SQL queries for the database operation, using MySQL, PostgreSQL, Oracle, etc.
7) Unit Testing (JUnit)
Unit testing is best known as a development process during the software development phase.
Knowledge of the widely adopted JUnit testing method is necessary to ensure high reliability and correctness in developed code.
8) Version Control Systems
Systems like Git can help in code collaboration and management. Knowledge of Git is a must for any backend developer, as it allows for versioning, branching, and collaboration with others.
9) Build Tools (Maven/Gradle)
Build tools, such as Maven or Gradle, help backend developers automatically build their projects and manage dependencies. Simply speaking, they help configure and manage a project.
10) Containerization
Applications have started to use containerization for deployment and management.
The backend developer can use Docker knowledge to develop, deploy, and run the application in an isolated environment.
11) Web / Application Servers:
Backend developers should also understand a web or application server. The Java application will be deployed using Apache Tomcat or WildFly servers.
12) Security Practices
Backend developers should be knowledgeable about security best practices, common security vulnerabilities, and secure coding practices. They must also be familiar with code analysis and security audit tools.
Collectively, these skills confer power to the Java application developer in building scalable applications that are efficient and secure, which leads to modern software.
That is why continuous updates to learn about recent improvements in Java and associated modern technologies are the heart and soul of a developing professional.
