Java is ranked as the world’s most popular coding language according to TIOBE’s Index. Although popularity is a limited metric, the TIOBE Index does give a certain idea as to how the development community appreciates Java’s ease and appropriateness of use, and for good reasons. Java allows building apps that perform at large-scale, are secure, scalable, and reliable.

There has been a great demand for Java developers since Java’s appearance more than two decades ago. At Koombea we’ve mostly used Java Enterprise Edition (Java EE), a collection of APIs that are part of the Oracle family of products. This version of Java provides an adequate runtime environment for developing and running all sorts of network applications, particularly those used by large companies.
Whether you are a large company or a small startup, we believe there are many reasons to develop your app in Java. This post discusses some of Java’s key uses for app development.
Object-oriented programming allows the code to work in terms of classes and individual objects (instances). Additionally, it allows reusing parts of the code, saving time and money throughout the development process. Java was not the first coding language to focus on the importance of object-oriented programming, nor has it been the last. Its importance on this matter can be explained in part because it came out at the right moment and had the right tools.
Java has helped make object-oriented programming popular throughout the world thanks to its data-oriented tools. It aids developers and programmers to think first about the data, making it an indispensable tool for almost anyone who works in data-related fields. This, paired up with its rich libraries, frameworks, and APIs, has helped position it as an industry standard for many object-oriented functionalities.
Let’s make one thing clear: Java is actually more than a coding language, it is a technology. Although most people think of it only as a language, Java is also a platform where applications run. Because it uses a virtual machine, it does not matter what operating system it runs on. This allows it to be a powerful tool for server-side based applications. Applications built on Java are able to run on a single computer or throughout various servers and clients in a network.
The fact that Java runs on a virtual machine also has other implications, like the fact that it can use bytecode rather than source code. As a result, one of the most important uses of Java is to develop code that will be accepted across different operating systems, making it a portable coding language. This means that the same code can be used across computers or servers with different operating systems.
Desktop & Mobile Apps
Thanks to its portability, Java can be used to develop apps for desktop computers as well as for mobile devices. This last has been one of Java’s strongest markets, particularly since its adoption in 2007 as Android’s preferred app coding language. Although other languages like Kotlin are currently fighting for the Android app market, Java still stands as a dominant player.
Java’s portability and server-side strength allow building strong web apps. As for desktop and mobile apps, Java web apps can run on different operating systems. Many important web-based applications across various industries are built on Java. The perfect example of a web app built with Java is Gmail. Websites like those of YouTube and Amazon also use Java.
Big companies have specific needs to run their business. Java offers a whole range of tools for this purpose. One of these tools is the already mentioned Java EE. By using its power developers can build apps that are tailored to specific organizational needs. Thanks to its active community, Java developers can access ample documentation on a wide variety of topics. Java EE’s APIs allow developers to use popular design patterns and the industry’s best practices in an easy way. Lastly, Java EE makes it easy to map the data that is being used in a given program. This is very important for companies that rely heavily on their data.
In-between App Communication
With an ever-growing universe of coding languages, apps, and operating systems, developers face the complex challenge of making every component communicate in an adequate way. Java Message Service (JMS) solves this problem by offering a standard API for enterprise messaging, solving communication problems without having to be restrained to a single API provider. The use of JMS minimizes the knowledge a Java developer needs while maintaining portability.
IoT & Cloud Development
Java has been gaining popularity within IoT and cloud development. It is expected that more devices adopt Java as their go-to-language for these purposes.
Code According to a Project’s Needs
Different versions of Java exist, each targeted for different needs. Besides Java EE, there are also available the Java Standard Edition (Java SE), Java Micro Edition (Java ME), and Java FX.
Java is a complete technology that offers not only a strong code language but also considerable portability between different devices and operating systems. It can deliver great results depending on what needs to be done.
