In 2021, the Java programming language turned 26. The Java language is evolving to keep up with tech innovations and software development trends. It is commonly used in various segments of software development, including web and mobile development, and such trending techs as big data, IoT (Internet of Things), blockchain and artificial intelligence (AI). From space exploration to genomics, from reverse compilers to robotic controllers, Java is at the heart of today’s world. 

Naturally, the number of jobs for Java developers globally continues to grow. Today, there are nearly 8 million Java programmers worldwide. And this is one of the main reasons why many organizations opt for this language in their development projects. An extensive workforce offer makes it easy for businesses to find well-qualified yet affordable Java developers.


Real-World Java Applications

There are many places where Java is used in the real world, starting from a commercial e-commerce website to android apps, from scientific application to financial applications like electronic trading systems, from games like Minecraft to desktop applications like Eclipse, Netbeans, and IntelliJ, from an open-source library to J2ME apps, etc.

Java Web applications

Java provides high security and simple coding, two elements that attract web application developers. Java is crucial in the E-commerce and web application space. There are a lot of  RESTful services being created using Spring MVC, Struts 2.0, and similar frameworks. Even simple Servlet, JSP, and Struts based web applications are quite popular on various government projects. Furthermore, open-source e-commerce platforms like Broadleaf makes designing e-commerce apps a simple task. Many governments, healthcare, insurance, education, defense, and several other departments have their web application built in Java.

Java Mobile Applications

It should be pointed out that the Android OS is closely based on Java, and that Android phones consistently garner a market share of over 85%. Add to this, the fact that most mobile app developers call Java their official programming language. Java is compatible with app designing software such as Kotlin and Android Studio. Java Platform, Micro Edition (alternately called Java ME or J2ME) functions as a cross-platform framework for creating applications that work across all Java-support devices.In addition, remember that mobile computing is outpacing desktop computing today, and you can see how you can’t escape Java.

According to the IoT Developer Survey, developers of embedded software solutions for IoT devices choose Java as the most important programming language in this field. One of the main reasons for that resides in the high portability of the Java language.

Java Desktop GUI Applications

GUI stands for Graphic User Interface, and Java enables GUI development through resources like Abstract Windowing Toolkit (AWT), JavaFX, and Swing. AWT features several pre-made components such as button, list, menu, and several third-party components. JavaFX is composed of a set of graphics and media packages, providing Swing interoperability and 3D graphics features. Swing is a GUI widget that offers advanced elements such as lists, scroll panes, tables, tabbed panels, and trees.

Financial Services Industry

Java is also very important in Financial Services. A lot of global Investment banks like Goldman Sachs, Citigroup, Barclays, Standard Charted, and other banks use Java for writing front and back office electronic trading systems, writing settlement and confirmation systems, data processing projects, and several others.

Java Scientific Applications

Science-related mathematical operations and calculations require developing apps that are extremely fast, highly secure, easily maintained, and highly portable. Java fills this need nicely. Powerful scientific applications like MATLAB rely on Java as part of the core system and interacting user interfaces.

Java Gaming Applications

Java and the gaming industry are a match made in heaven. Java supports the jMonkey engine, one of the most potent 3D engines available today. And 2D games are a snap too; just couple Java with CSS, and you’re good to go. So, no matter what kind of games developers are designing, Java has them covered.

Enterprise Applications

Java is the first choice of many software developers for writing applications and Java Enterprise Edition (Java EE) is a very popular platform that provides API and runtime environment for scripting. It also includes network applications and web-services. JavaEE is also considered as the backbone for a variety of banking applications which have Java running on the UI to back server end.

Software Tools

Many useful software and development tools are written and developed in Java e.g., Eclipse, IntelliJ Idea, and NetBeans IDE.

Big Data technologies

Hadoop and other big data technologies are also using Java in one way or other e.g., Apache’s Java-based HBase and Accumulo (open source) and  ElasticSearch as well. Additionally, Scala, a competing programming language, owes its origins to Java. Scala was created to address some of Java’s drawbacks.

Java Business Applications

Big enterprises have big problems. That is why these organizations turn to the Java EE platform to develop large-scale, multi-tiered network applications that are scalable, reliable, and secure. Java offers features that deliver a powerful app that is less complex by providing tools like a development model, API, and runtime environment. These features free up developers to concentrate more on the app’s functionality.

Cloud-Based Applications

Cloud computing means on-demand delivery of IT resources via the internet with pay-as-you-go pricing. It provides a solution for IT infrastructure at a low cost. Java provides you with features that can help you build applications meaning that it can be used in the SaaS, IaaS and PaaS development. It can serve the companies to build their applications remotely or help companies share data with others, whatever the requirement. 

Cloud-Based Applications

We come to know that Java is a “blue-collared” language, touching every field of software development. It can be used according to business needs. With these applications, we realize the need for Java in the real-world.
