Widely popular programming language, Java, is the high-level programming and a platform independent language. It is the lifeline of all developments today and requires its interference in almost every development curated by developers. While people may consider Java as simply a programming language, it has its own set of use cases.
We are here to burst the bubble and take you through the uses of Java language in various fields. We are sure by the end of the blog, you would be surprised by how Java has its fair share of involvement in almost everything you use. Let’s get started.
1. Desktop Applications
To begin with, we shall take you to the most basic use of Java programming language. Java enables development of the desktop application, but not just any applications, it supports in the development of Graphical User Interface (GUI) applications. It uses various tools available in Java like:
- Abstract Windowing Toolkit (AWT): It consists of components that are already built and available, like buttons menus, lists, and loads of third-party components,
- Swing: It is a widget toolkit that provides advanced toolkits like scroll panes, tables, trees, lists, and tabbed panels.
- JavaFX: It is basically a group of media and graphics packages
2. Android apps
You should know that Java is used to built Android mobile apps. Yes, if you are using an Android device then you surely are using apps that are built on Java programming language. With the advent of the Android operating system, demand of Java development has been increased in manifolds. Android app development companies seek to hire Java Developers for different types of application development projects. Although recently Kotlin has been announced as an official Android programming language yet the many tools and frameworks of Android is not compatible with Java.
3. Internet of Things
The latest vogue in the industry is IoT. Everybody is talking about it since it’s all about connectivity and enterprises are looking at ways to implement IoT into their system. From smart sensors in industries to smart homes in public, IoT is everywhere.
Java has smartly touched the base of IoT as well. The very popular Nest thermostat is the combination of Java language and Artificial Intelligence. On the other hand, smart vending machines are Java based. It uses software that tracks inventory, temperature, humidity, and location. Another interesting point not to be missed is that many wearable device applications are built in Java too.
4. Healthcare Industry
It may sound surprising, but Java has played an important role in the healthcare industry too. The booming and technology-driven healthcare industry is all about doctors connecting with patients digitally. Chatbots have played an important role in ensuring connectivity between doctors and patients despite their location.
One such project – Doctor Online, has Java enabled system that has used suites of Java modules that has made doctors and patients interaction convenient and hassle-free.
Likewise, e-commerce industry too has taken the advantage of Java modules in building chatbots that track the shipment, connects with customer support, chooses the right material giving the user a more personalized experience.
5. Data Analysis
Data analysis these days is an important profession as we have loads of adapt to process and forecast user’s behavior etc. Data analysis techniques are used to discover new outlines in large extents of data and understand complex processes involved.
Java language is used for many data analytics tasks, most likely in Extract/Transform/Load processes. There are a wide variety of tools in Java that are used to perform data analysis which includes libraries and frameworks.
6. Financial Service Industry
Java has elated the financial industry as well. There are many global Investment banks like Goldman Sachs, Barclays, Standard Charted and others who are using Java language to write:
- Front and back office electronic trading system,
- Settlement and confirmation systems,
- Data processing projects
- Stock market trading system projects
7. Web Applications
Not to miss, Java had traded its importance in the development of web applications too. Java language provides an easy way to program web applications with the help of via Struts, Servlets or JSPs. They also offer a very high level of security as well. This has eventually pushed many government applications to be built on the Java programming language. Other industries have also utilized this benefit and have web applications created for healthcare, education, defense, social security, insurance and more.
8. Space Applications
Java language is being utilized to develop interesting applications for space. Nasa has realized the potential of Java and has been involved in curating applications for space.
For instance – Nasa built World Wind which is a software development kit that lets scientists zoom in from outer space and explore any location on earth easily from space.
To explore more on the topic, there’s a blog post on developing NASA’s mission software with Java, which will give you in-depth details of the usage of Java in a space mission.
9. Self-Driven Cars
Future we are looking towards is self-driven cars. There would be tons of other technologies included in the development of self-driven cars like robotics to steer wheels, sensors to avoid collisions and more. However, before allowing the cars to place on roads for testing, Java would be needed to combine all these technologies into a package that guarantees extreme reliability and support.
10. Building Games
Not to be missed that most of the digital games that we play today are built on Java language. Plus, with the increasing popularity of mobile phones, Java language is extensively used to build games. The Open JavaFX (OpenJFX) graphics package available in Java eases the burden of curating images that enhances the view of any game. Other than this, there are gaming development sites, such as Java-Gaming.org, that is specifically for Java game developers to fulfill their needs and interests in building the game.
In the end note, it’s obvious to say that you name a segment and you will find Java somehow involved in it. The horizon of Java has expanded to all segments due to its rich features and functionalities that all developers think Java before they think of any development. The use cases surely are going to be in expansive mode since we are sure to see Java in other segments very soon.
