Learning Java and becoming proficient in software development requires dedication, practice, and continuous learning, but with the right resources and perseverance, it is achievable for many. 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. Popular for its versatility and ability to create a wide variety of applications, learning Java opens up your possibilities when coding. With it, you’ll be able to develop large systems, software, and mobile applications — and even create mobile apps for Android.
- While developers often choose to specialize in one of the two, it helps to have an understanding of both.
- Qualified professionals from various backgrounds can develop a java developer skillset to become successful Java developers.
- It can be used to create server-side applications, mobile apps, and games, or to equip home appliances with basic features.
- As Java developers and software developers have similar roles and skills, many professionals transition between the two roles for variety, a new challenge, or to learn new skills.
A new Java Developer should expect to put just as much time into maintenance and optimization as they do into program architecture, perhaps more. This might include working closely with a stakeholder, Project Manager, or Senior Java Developer, and many times includes all three. Discussions likely revolve around prioritizing important tasks first, determining overall scope of work and course of action. The Java developer may report to a senior project manager or overall IT manager, who then reports up the chain to the CIO or an otherwise senior leader in IT. Interestingly, PHP, a Java descendant, is used in over 82% of websites whose server-side programming is known.
What Is Object-Oriented Programming?
Java is old enough to make people roll their eyes, but still relevant enough to get a slew of new features now and then. 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.
Java developers use various tools, libraries, and frameworks to create software solutions for different industries, even for software engineers or web developers. The role of a Java backend developer extends to creating and linking different layers, including the web server, application server, and database. This includes using web technologies such as Java Server Pages (JSP), Servlets, and Java Server Faces (JSF) to generate dynamic content and foster interactive user interfaces. Java developers can be software engineers, mobile developers, or backend developers.
What Does a Java Developer Do?
Many seasoned Java programmers think of NetBeans, Eclipse and IntelliJ IDEA as the top three IDEs for enterprise application development. But there are cases where a more lightweight IDE such as DrJava, BlueJ, JCreator, or Eclipse Che is the best choice. As more companies use connected devices, machine learning algorithms and cloud solutions, the demand for skilled developers continues to grow. Many analysts foresee a scarcity of senior-level programmers in the near future, making it difficult to staff new software initiatives. Demand for mobile app developers could soon easily exceed the available supply. Java’s rich ecosystem of libraries and tools helps developers create flexible and scalable APIs, enabling different parts of an application to communicate seamlessly.
By securing feedback from testers and visionaries, the Senior Java Developer can add, remove, and debug features necessary to the project’s overall success. They are also viewed as a team leader who may delegate these tasks to other developers who focus solely on program architecture. However, it would be a mistake to view Java only in terms of legacy applications. The Java java developer course language forms the heart of the Android operating system, which powers by far the largest share of the world’s smartphones. Java is also among the most popular languages for machine learning and data science applications. Its robustness, ease of use, cross-platform capabilities and security make Java the language of choice for internet solutions in many enterprise shops.

According to our survey results, more organizations are turning to Java as the language of choice to help modernize their applications. Not surprisingly, demand for Java Developers is expected to grow between now and 2024 by up to 19%. The median salary for US-based Java Developers is over $70,000 and goes up depending on career level, experience, and location. An Oracle Certified Master, Java SE 6 Developer certification requires 12 months of being an Oracle Certified Professional Java Programmer. Applicants must also satisfactorily complete a programming assignment over a 12-month period where they write code for a small business system according to technical requirements.
Qualified professionals from various backgrounds can develop a java developer skillset to become successful Java developers. Bachelor’s Degree or Master’s degree in Computer Science, Computer Engineering or related field is preferred by many employers. Hands-on software development experience, especially in Java, will boost your chances of bagging a high-paying Java developer job.
Responsibilities:
Soft skills help people succeed at work and include communication, problem-solving, and teamwork skills. The JavaScript programming language allows you, as a Java developer, to create dynamic and interactive web applications, significantly enhancing the overall user experience on a website. As a feature-packed JavaScript library, jQuery helps you streamline your web development tasks, such as designing drop-down menus.
RESTful APIs and WebSockets are some popular Java-based technologies used for API development. The whole microservices buzz made frameworks such as Spring Boot very popular. 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).
Types of IT Teams
Developers primarily use Java for server-side development and JavaScript for client-side projects. The front end and back end are essential components in the makeup of any web application. While developers often choose to specialize in one of the two, it helps to have an understanding of both.
You will be part of a talented software team that works on mission-critical applications. Java developer roles and responsibilities include managing Java/Java EE application development while providing expertise in the full software development lifecycle, from concept and design to testing. We are seeking a skilled Java Developer to join our development team.
