What is Java?

Java is a widely used programming language which can create everything from mobile and web apps to games, enterprise software and much more.  It has been around for over 25 years and has been a popular choice with developers since it was first launched.  

The Java website describes it as a programming language and computing platform. This is due to the way Java works, allowing developers to code an application in the language, which is then translated by the platform (or compiler) into machine computer code called “bytecode” that operating systems can understand.  

This means that any device or system that can support the language by means of an installation called Java Virtual Machine (JVM) can run the resulting program.  JVM’s can be installed almost anywhere. This means that despite the slight barrier to use, many devices and operating systems have one pre-installed.

Java is open-source technology that allows developers to create an enormous amount of software applications for a huge range of devices such as mobile phones, TVs, and games consoles to name just a few.  Software developers gravitate to Java as an invaluable tool for creating software as it is based on the C++ programming language, meaning it is familiar to programmers as soon as they begin to use it.

There is a much repeated slogan of Java that is “Write Once, Run Anywhere” meaning that it can be written for one operating system but can also be run on another.  This is because of the aforementioned machine code that is read by the computer running the application.

Java therefore is an object oriented programming language that is incredibly popular with software developers across the world. The 2022 Toibe index shows it as one of the top 3 most used programming languages. Part of that success is likely due to its portability and platform independence, making it an almost default choice for many enterprise level businesses.

A brief history of Java

Java first appeared in 1995 and was produced by Sun Microsystems.  Initially proprietary software it is now an open-source project backed by Oracle.

Java was able to rapidly excel in creating software that could run on any device. This acceleration was helped by the growing number of devices used by businesses and people during the 1990s. In the 5 years following its initial release in 1996, Java gained over 2.5 million active developers. 

It is estimated that there are now between 8 and 9 million Java developers creating and powering everything from games to mobile operating systems and much more.

Today Java is everywhere. Oracle, who now oversees Java, reports that there are 51 Billion Java Virtual Machines  (JVMs) globally powering a huge range of products and services such as…

  • Mobile Apps – Spotify, Wikipedia & Twitter among others.
  • Web Apps – LinkedIn for instance.
  • Games – Minecraft or Runescape anyone?
  • Scientific Software – Nasa Worldwind and Mars Rover Controller use Java.
  • Internet of Things (IoT) – Everything from Smart TV’s to Electric Vehicles.

With 51 billion JVMs this list doesn’t begin to cover the possible uses.

Why Use Java?

Java is a tried, tested and mature programming toolset that has stood the test of time and extensive use.  After almost a quarter of a century Java is still one of the most popular software development tools in existence, used and loved by millions, and well supported by Oracle, as well as its own open-source community. Java is now almost 30 years old and has been in continual development for all that time. 

A short list of the reasons for, and benefits of using Java include…


Java is considered easy to learn with superb documentation and a host of learning resources.  There is a development kit that provides all the tools required to write programs and a runtime environment to execute the programs.  

Libraries have been built up over 25 years that provide functionality to achieve almost anything much easier than starting from scratch.


Java is multi platform, applications created for a particular device can easily be run on a different device or operating system, meaning there is no need for a rewrite. 

The versatility of Java means programming applications for web, mobile, desktop or other platforms can be achieved using a platform other than the intended one.  For instance, developing a windows app can be done using linux and the app will still run.

Java features such as dynamic coding, platform independence and network centric programming just add to it’s flexibility and versatility.


Java is secure.  Even if a user were to have some untrusted code from a network it can be run in a secure environment ensuring the best possible environment to avoid harm or infection in the program.  Security and access levels also exist. These can be configured for each application or part of a program, with specific access rules eliminating many security risks.

Open Source

An open-source project of this maturity has an enormous community behind it.  Fully supported by Oracle, Java is stable, secure and in continual development.  With literally millions of developers in the community flagging up bugs and vulnerabilities continually, any threats are swiftly identified and eliminated.

These are just some of the benefits of using Java in a software development project.  In a crowded market sometimes the stability and comprehensiveness of a mature project like Java is more attractive than the latest new, shiny thing.

Why Hire Java Developers?

Java developers design and develop software and other applications that use Java programming language and computing platform, using the Java Development Kit (JDK), which provides the necessary tools for creating, debugging, and deploying applications.  In addition, the JDK contains a Java Runtime Environment (JRE) that allows developers to run and test applications.

A skilled and accredited Java developer is fluent in coding with the required toolsets and libraries.  While other object oriented programming (OOP) developers will find the language familiar, they will not be competent enough to develop successful Java projects. 

The additional learning curve and costs involved in upskilling an OOP developer to being competent in Java is generally not a good option when it comes to finding the most cost effective and time efficient development solution. 

A fully vetted and certified Java developer provides additional value to projects by leveraging the full power of Java, and associated tools and platform. Highly skilled, experienced developers are able to ensure that the build and management of software applications for any platform runs smoothly and effectively. This ensures you can get outstanding results at the end of your project regardless of any dependencies and integrations required. 

The same expert can also help overcome many project management challenges. By fully understanding the software in use and the desired deliverables, they can help predict, more accurately, how challenging and time consuming the project will be and the likely roadblocks to completion. 

In order to ensure a successful outcome for your Java project it's important to work with a developer who is fully versed in the language and toolset, as well as its libraries and nuances. While Java developers’ number in the millions, so do the projects and businesses they work for. Therefore, finding the right Java developer for your project can be as challenging as it is essential.

Why use Deazy to hire Java developers? 

Java is in huge demand for software projects small and large, enterprise applications, mobile and web apps and more.  As more businesses and organisations adopt Java for the development of their software projects demand to hire Java developers is high. 

Since Java has a few moving parts that work together, developers need to be competent in the full toolset.  Finding a suitably qualified and experienced Java developer may not always be as simple as it seems.

Due to Java’s popularity and use in millions of projects across web, mobile, gaming, Internet of Things and other areas, the competition to find skilled developers is high. Companies of all sizes, from small app development projects to large enterprise level and government backed organisations have their entire organisations and offering based in Java.

With a limited pool of certified developers and massive demand for the skillset, hiring high quality Java certified developers is not only a time-consuming task but can also be an expensive affair.  Attracting the best talent from the available pool is absolutely crucial to the success of an ambitious development roadmap.
