To become a junior Java developer, you need to learn the basics of Java through formal education or self-teaching, complete internships and personal projects, and contribute to open source projects. Job interviews will test your problem-solving skills and ability to apply concepts to programming problems. Previous experience working on Java projects is also important.
As a junior Java developer, you will contribute work to software engineering projects being developed in the Java programming language. This should give you practice applying basic Java principles to create real-life software, and a chance to learn the programming craft from experienced developers. To become a junior Java developer, you typically need to demonstrate that you’ve learned the basics of the language and are able to creatively apply that knowledge to create new software.
You can usually learn the basics of Java by completing a formal computer science program at the graduate or undergraduate levels or by teaching yourself through the variety of resources available in print and online media. Earning a degree in computer science typically offers a structured series of classes to learn the Java language, as well as mathematical and software engineering concepts to help you program more efficiently. You can also learn Java through books, free online tutorials, and forums that allow you to ask programmers technical questions.
After learning the basics of Java, you must take steps to highlight your programming skills in your application to become a junior Java developer. You can do this by completing internships and undertaking personal programming projects. It is generally easier for computer science students to find unpaid programming internships, and they are often able to complete personal programming projects for class credit. Contributing source code to open source projects, whether you are a computer science student or a self-taught programmer, is another way to bolster your resume and programming credentials. The competition can be tough to become a junior Java developer, but if your resume impresses a company’s human resources department, they’ll call you in for an interview.
A job interview to become a junior Java developer is usually part interview and part audition. Companies often expect junior developers to have a basic competency in the mechanics of programming and to learn how to become skilled programmers from a combination of on-the-job experience and guidance from senior developers. To that end, interviewing for a junior Java developer position will likely not only examine your academic knowledge of language mechanics, but also how you can apply these concepts to produce novel solutions to a variety of programming problems.
Employers often consider your ability to solve problems as a reflection of your aptitude for growth as a developer. This can be a big factor in deciding whether or not to hire you as a junior developer. Previous experience working on Java projects, not just doing homework for programming classes, can help you get to this last step in the hiring process and give you the hands-on experience to successfully answer any programming questions.
