What Is a Junior Java Developer and How to Become One

By ZipRecruiter Marketplace Research Team

Junior Java developers are entry-level programmers who are part of a team of coders and developers. They work on both front-end and back-end codes to build an application. Being a junior Java developer requires extensive knowledge of coding and the program language JavaScript to develop and troubleshoot products. As a junior Java developer, you run tests to pinpoint errors, migrate code and data, and ensure the program is integrated with other company developments.

Many aspiring junior Java developers start their careers by obtaining a bachelor’s degree in computer science to learn Java coding languages, but some choose to teach themselves Java through online programs and coding academies. Mastering these programs may take weeks or months of study. Practice all aspects of front-end and back-end processes to create applications and become proficient in various Java languages to give you a substantial portfolio and make you a strong candidate for these entry-level positions.

A junior Java developer needs to know the programming languages frequently used on the job. Java is the primary coding language that junior Java developers need to master, but they also need proficiency in other coding languages such as JavaScript, HTML, and CSS. Program implementations such as Oracle HotSpot or the GNU compiler for Java are also useful. Potential job candidates should know SQL queries, database operations, and data structures. To be a great junior Java developer, you need to know how to communicate with your team, ask questions, and learn new skills.
