A Java Developer is responsible for designing, implementing, and maintaining Java-based software and applications, contributing to all stages of the software development lifecycle. They thoroughly analyze user requirements, envision system features, and define application functionality. Besides, a Java Developer also proposes changes to the current Java infrastructure of the legacy applications.
JVM (Java Virtual Machine) is an abstract computing machine enabling a computer to run a Java program. It converts Java bytecode into machine language, making Java a platform-independent language. java developer course This resource will help you develop an onboarding checklist for new hires.

Core Java Developer
Java developers are responsible for designing, coding, and testing software programs. This is not just limited to the development of software but also includes the development of mobile apps, web pages, websites, and more. Java developers are in high demand these days because they have a wide range of skills that can be applied to many different fields. Before we dive into the specifics of a Java developer role, let’s start with the basics. Java is a programming language, widely considered to be one of the most popular in the world. Not to be confused with JavaScript, Java itself is also a platform for application development, which many programming languages are not.
As a Java developer, you’ll likely be part of the IT team within an organization. Depending how your enterprise is structured, there could be a single IT team, or many smaller IT teams that works on individual projects. Being a Java Developer opens many great opportunities for you in the IT industry, from established roles to transformative and highly evolving ones. Are you still uncertain of whether you have the right mix of skills for landing a job as a Java Developer?
Time management
The Bureau of Labor Statistics has predicted 30% job growth in the software development industry between 2010 and 2020. The professional level certification is the foundation for most higher level certifications. As candidates progress beyond the professional level, the certification process begins to mimic the activities of a real world developer more closely. High level certification entails completing a design project and an essay exam. An ideal Java developer can have a range of background requirements. Hands-on software development experience, particularly in Java, would augment a candidacy; significant experience could replace the need for formal education.
These specialized programmers may collaborate with fellow engineers and web developers to create business applications and websites using said language. It’s essential to be meticulous in executing Java commands properly. However, most employers require applicants to have a degree in computer science, information systems, mathematics, or any other related field.

If it seems like a lot, you might be surprised to learn that the figure falls short. Three billion devices — that’s what the Java Setup executable stated when you installed the Java client… in 2013. Since then, every metric suggests that the compiled-and-interpreted language has kept growing, both in devices and in users. In 2023, a whole decade after Java claimed to dwell in 3 billion devices, 85% of the world’s smartphones rely on an OS developed on Java. With GitHub estimating that, in 2023, there are 100 million developers worldwide, we can safely estimate that at least a third of them are Java developers. In the US, the average yearly salary of a Java developer is around $97,000, which includes base pay and bonuses.
- Backend development with Java involves creating and managing server-side applications and services that power web and mobile applications.
- Users choose it for web development, mobile development (especially for Android apps with Kotlin), desktop applications, embedded systems, and big data processing, and more.
- If the role requires knowledge of other tools, such as Docker or SQLite, make sure you ask about these too.
- Frameworks are collections of libraries, functions, and code that enable programmers to code faster without “reinventing the wheel” each time.

Become a Software Development Professional
Understanding these terms will allow Java developers to navigate through the development process smoothly, enabling them to build efficient, robust, and scalable applications. Spring Framework is a comprehensive framework for developing Java applications. It provides infrastructure support, so developers can focus on application development instead of routine system-level processes. Java developers, like other software professionals, need to understand a host of technical terms and jargon. However, there are some specific terms that are central to Java development. Familiarity with these will boost your proficiency and help you effectively communicate with team members and stakeholders.
Even if Steve Jobs pronounced it defunct in 2007, this extraordinary piece of tech has remained a stalwart in the world of programming languages since its debut in 1995. It is a versatile, object-oriented, and platform-independent language that can run on any device that supports the Java Virtual Machine (JVM). Because it is a compiled language, Java development requires a separate installation — hence the installation file we referred to. But because its source code is initially turned into a binary byte code, Java can be considered a compiled and interpreted language.
Version control systems (VCS) enable developers to work together on the same projects simultaneously, managing and merging changes from different contributors. Tracking all changes also helps with identifying issues and debugging programs. Java developers are professionals who build, maintain, and troubleshoot programs using Java. Most employers want Java developers with projects under their belts. That means you need hands-on experience to build a portfolio and get a job. However, many employers value bachelor’s and master’s degrees as well.
