Everyone, techy or not may have at some point heard of the word, Java. It is one of the most popular programming languages and has been widely used for app development since the 90s. It has also been the most trusted and go-to language for most tech companies, entrepreneurs and developers.
Whether startups or existing, businesses always look forward to achieving dynamic and strong digital capabilities to grow their businesses and stay at the top in the industry. As per the report of Statista, as of 2021, 56 per cent of the respondents use Java, Python, SQL, and HTML/CSS as the top five programming languages in the world.
However, despite it being a popular language, hiring an efficient and well-experienced java developer may be an extreme sport. A thorough check on the skill and quality of work of the developer is a prerequisite to finding the right fit.
In this article, we will explore the skills you should pay attention to before hiring a java developer;
Basic Java skills:
To explain the role of a Java developer in clear terms, She/He is responsible for developing various software from desktop to web to mobile applications. Therefore, no matter what company you may be hiring this developer from, ensure they are familiar with the basic Java skills and technologies. Some of which include: --- Object-oriented programming skills
- Relational databases such as MySQL, PostgresSQL, and MariaDB.
- Design patterns in Java to solve routine problems faced in the software designing cycle
- Popular version control systems like Git and BitBucket
- Web frontend technologies like HTML, CSS, and JQuery
Java Build Tools:
Each programming language has certain tools unique to them which perform different tasks. Having knowledge and efficiency in different Java build tools will increase the chances of Java developers getting hired by growing businesses.
These build tools help to automate the source code applications. A few of these build tools are Apache, Sonatype, Gradle, Nexus, and Cmake.
Java Testing Tools:
Apart from coding, it’s an added benefit if Java developers are proficient in testing tools as well. Testing tools allow the developers to test their code through a separate database without using a web browser.
Tools like TestNG and Selenium allow the Java developers to test multiple processes together and develop a high-quality, powerful application.
Additional Languages and Technologies:
In addition to the language, the most popular Java skills that Java developers should have are Android, Selenium, Spring/Spring Boot, and JPA/Hibernate.
Since different languages and technologies are meant to perform different tasks, being efficient in them will come in handy for a Java developer.
Having knowledge of DevOps tools is considered a must-have among the top Java skills. A Java developer will be much in demand if they regularly update their skills and learns DevOps tools along with Java tools.
Some of the important DevOp tools worth learning are Docker, Kubernetes, Jenkins, Chef, and Maven. Thus, it would be great if the Java developers you hire are knowledgeable about DevOps tools.
