It’s a good time to be a web developer.

According to the Bureau of Labor Statistics, web development experienced a 30% job growth between 2010 and 2020 – an extraordinary rate when compared to other occupations. No wonder so many people decide to specialize in web development! Today, we’re focusing on Java development in particular, and giving a quick snapshot about why java developer jobs are in hot pursuit.

What is Java?

Developed in 1995 by Sun Microsystems and owned by Oracle today, Java is a class-based, concurrent, and object-oriented language. As one of the oldest programming languages around (and the third most popular), Java is used by about 9 million developers today.

Java-based applications are known for their speed and scalability, which explains their high usage in software, computer games, and mobile apps. Prominent companies such as LinkedIn, Indeed, and Chase, among others, rely on the language for a multitude of tasks.

Even when smaller companies opt to use different languages to build their initial programs, they often end up switching to Java as they grow to a size that requires more speed and sustainability over time. Though Twitter is anything but small, the company falls into this category, as it began using Java while expanding beyond its early stages.

What is a Java developer?

If Java itself sounds intriguing, you might be interested in becoming a Java developer. These developers work with Java to develop, manage, and design applications. Since the language has a wide variety of functions, the work can range from software, to games, web applications, and different utilities for internet and mobile devices.

Most of the time, developers work alone, and on their computers (no surprise there), but will often collaborate with other software developers and engineers, depending on the assignment.

What are Java developer skills and responsibilities?

As with any occupation, a Java developer’s roles and responsibilities will differ depending on the particular company and position. Variability aside, most Java developers are responsible for duties throughout the design, development, and testing processes.

Here are some of the most typical responsibilities:

  • Develop efficient and testable code
  • Test, debug, maintain, and analyze Java application software
  • Identify, recommend, and implement changes to improve the application and process
  • Ensure that the design complies with requirements

Each assignment may differ in scale and scope, but that’s what makes the work exciting!

I’m interested, but am I qualified?

There are a range of qualifications depending on the role you’re interested in. The most common education requirement is a B.S. or M.S. in computer science, computer engineering, mathematics, or a closely related field. Companies often recommend having a professional certification as well.

Studied something different in college? Don’t fret! Knowledge and experience in Java development are the most important considerations. Even a candidate with no formal education, but who has deep knowledge of and experience in Java, will likely be considered for the position.

Personal anecdote – The writer of this article has a good friend who falls into this category. He learned Java via affordable online courses, worked his way into an internship with a large company, and ultimately, into a full-time role. It isn’t easy, but it’s possible!

What’s next for future Java developers?

The future of the Java developer job market is bright. In the past decade, Java has been one of the most desirable programming languages and isn’t likely to lose its popularity anytime soon. Java development is not only one of the fastest growing occupations, but it also has high job demand across industries.

Many organizations are still turning to the language to scale up their web presence and modernize their applications. So, whether you’re a complete beginner or an expert with years of experience, you’ll have plenty of flexibility and opportunities to move up in your career.
