10 Astonishing Applications of Java – Where Java is Used in Real World?

Sun Microsystems brought Java to the world of programming in 1995. Yeah we learnt that Java contains a plethora of features but where are they used? Where do such features bond together to complete beautiful softwares which benefits people from all over the world? Java has been a prime component for developing a plethora of real time applications, embedded systems web apps and a lot more.
We are going to learn about them here in this article,so gear up!

Java has been the backbone for developing Macintosh, Windows and even UNIX based systems. Oracle acquired Sun Microsystems in 2010 after which they revealed that Java was now running on more than 3 billion devices.

Applications of Java

Some of the many applications of Java are:

  • Desktop GUI
  • Applications for Mobiles
  • Embedded Systems
  • Web Applications
  • Application Servers
  • Web Servers
  • Applications for Enterprises
  • Scientific Applications
  • Big Data Technologies
  • Business Applications

1. Desktop GUI

Java has a lot of features which are particularly inclined towards GUI development. There are special packages such as Abstract Windowing Toolkit, JavaFX and Swing which aid developers to stitch together various components of GUI such as window panes, toolbars to create fluid and responsive interfaces for the users. Swing is a little bit advanced containing options for developing progressional GUI elements such as trees, tables, tabbed panels and lists.

2. Applications for Mobiles

Whenever there is a need for developing applications for android what is the goto IDE we all talk about? Yes, Android Studio. However after the advent of Flutter, mobile applications can also be developed by Dart. But Java still has the monopoly of being the most used language for developing mobile apps. It is even compatible with Kotlin. The reason for Java being the language for android development is that android applications use Dalvik Virtual Machines .

On the other hand Java uses Java Virtual Machines, hence its easy to develop and bundle the class variables in Java. It becomes entirely platform independent. These are further bundled into Android Application Package(APK).

Java’s Object Oriented Principles make it simpler and more effective for developing individual components of an application.

3. Embedded Systems

A lot of electro mechanical applications use embedded systems like microchips and mini computers to perform dedicated tasks in a system.
Several systems such as SIM cards and televisions still use Java as their building blocks.

Java acts as a core for TV devices and Blu-Ray disc players .

4. Web Applications of Java

Java is also useful for web development. Java has inbuilt packages such as Servlets,Struts and JSPs. These packages are easy to code in and grasp at the same time. These technologies also provide high security, allowing the development of applications pertaining to health,social security, education etc.

BroadLeaf, which is a huge open-source eCommerce website, involves the use of Java.

5. Application Servers and web servers

What is an application server in the first place? Well simply put, its a framework which helps and provides in developing a server environment and applications for the web. It has a set of components which are accessible to developers through an API predefined for that platform. In the case of Java Application servers, the server acts like an extended virtual machine. It handles database connections on one hand and the assigned web client on another.

Java also finds its immense application in commercial application services like WebLogic,WebSphere

However, speaking of a web server, it’s a server software/hardware which satisfies the client requests on the WWW(World Wide Web). It has the job of storing, processing and delivering web pages to clients/users. The communication takes place by using a HTTP request.

Some very popular web server applications such as Tomcat, Simpoe,Rimfaxe Web Server are all developed using Java.

6. Java Applications for Enterprises

What are enterprises? Well, simply put, if a company is aimed for profit whilst being associated with entrepreneurial ventures, it can be called as an enterprise. You can think of an Enterprise as any company which runs for profit.

Now, a lot of enterprises use applications which use Java. For example, Muriel is a high frequency trading application designed entirely by Java EE(Enterprise edition). It is responsible for providing runtime environments and APIs for running and scripting enterprise softwares.

7. Scientific Applications of Java

MATLAB is one of the popular scientific applications which involve the use ofJava .They use Java for both the UI and the core system. Why? Because Java has high portability and low maintenance. Hence the applications are fast and reliable they are able to work with a large amount of data at hand.

8. Big Data Technologies

Java being fast, reliable and robust is useful for many applications to manipulate and study Big Data. With the help of frameworks like Apache Mahout, Apache Spark,Java JFreechart which are useful while working on big data, Java reserves its place as a valuable language for Big Data applications.

One of the main reasons for Java being the core language for a lot of these technologies is that Java is ingrained with Open source communities.

9. Business Applications of Java

However Java’s EE provides API, development models and runtime environments which makes the development of these applications relatively easy.

During the building of business oriented applications, Java’s EE edition is useful in order to create large scale, multi tier, scalable and secure network applications. The security and reliability requirements of a business application make it complex.

10. Distributed Applications

Distributed applications are such that they are dynamic on the platforms they are working on. They have several common requirements like the environment being distributed and dynamic at the same time. They also have to be equally efficient on whatever platform they are working on. Also, they have support for all kinds of processors which makes them versatile.

The JINI(Java Intelligent Networking Infrastructure) is an essential tool which features plug and play. It means that whenever a device is plugged into a network, it can immediately provide its services. The distributed services are used by other nodes on the network as and when required. Javaspaces is an application which uses this concept. It’s basically an online bulletin board of multiple collaborators. It’s a network accessible repository for objects. Kind of like facebook for business. If you have an apple to sell, you put it up there and the interested buyer mentions his price there and so on.

Summary

Java is hugely popular, hence there are so many applications of Java from which we did observe a few in this article. As we progress through the DataFlair Java Tutorial series, we would come to know a lot more about the intricacies of Java which paves the way to great applications which are dynamic,fluid, and easy to use at the same time.
