Who Uses Java? Companies That Use Java and What Java Is Used For

Ufuoma Ogono - August 05, 2022

Java is a computer language known to everybody who has ever heard of programming. This is understandable given that it is one of the most widely used programming languages on the planet. In this article, you’ll learn about who uses Java, which companies have available positions for Java experts, and where to find some of the best Java bootcamps .

What Is Java?

Java is a class-based, high-level, object oriented programming language that James Gosling designed in 1995. The multi-paradigm language is one of the most popular programming languages in the world of computing. This is because the programming language was created with the intention of requiring as few dependencies as possible while it is being implemented.

The Java virtual machine (JVM) is the technology that allows Java to be used on every type of computer in the world, irrespective of its underlying infrastructure. Since Java is a high-level programming language, it is compiled in the Java virtual machine and turned into Bytecode, a machine-readable language.

Along with Python and JavaScript, Java is currently one of the most popular programming languages among programmers. The information below shows that developers still use Java as their preferred class-based programming language.

What Is Java Used For?

While the primary use of Java is for programming computer software, there are many other specific uses that are highlighted below. This list will help you choose a career path if you want to learn to code in Java or become a Java developer.

Server-Side or Backend Application Development

Java can be used to create the functional components of an application. Users do not interact with these parts but they are essential for the front end to thrive. Java’s Write Once, Run Anywhere (WORA) philosophy makes it an ideal server-side development tool for all types of operating systems.

In the United States, server-side Java developers earn an average of $121,513 annually, according to ZipRecruiter. Salaries can go as high as $173,500, depending on location and level of experience.

Full Stack Web Application Development

Java can be used to create a variety of applications for the web. As a tool for web development, Java 8 can be applied to design both front end and backend applications. While Java is used as the core technology for full stack web applications , developers will also require knowledge of other web technologies.

If you become a full stack Java developer in the United States, you should expect to earn an average of $119,892 annually, based on data provided by ZipRecruiter. Your salary could range between $63,000 and $167,500.

Distributed Application Development

Java is one of the few programming languages that can be used to build applications either for a single computer network or a distributed system. Distributed Java applications have components spread across various systems rather than a central mainframe.

This is thanks to the Java Intelligent Networking Infrastructure (JINI). According to ZipRecruiter, people who specialize in distributed systems earn up to $134,214 yearly. Salaries may range between $44,000 and $203,500, depending on various factors.

Cloud-Based Application Development

Java is also an ideal programming language for building cloud-based applications. Developers can use Java to create software as a service, popularly known as SaaS. These applications are gaining traction across industries because they are more secure and affordable than traditional systems. Java cloud developers earn $110,645 annually , as ZipRecruiter indicates.

Big Data Engineering

Apart from traditional software development, Java 8 has been applied in big data engineering, particularly big data processing. It is memory-efficient, offers automated memory distribution, and facilitates garbage collection.

According to ZipRecruiter, you should expect to earn an average of $118,943 yearly as a Java big data developer. Depending on the state and your level of experience, salaries could range from as low as $52,500 to as high as $168,000.
