Where Java is Used

Java has been the backbone of developing Macintosh, Windows, and even UNIX systems. Oracle acquired Sun Microsystems in 2010 and later announced that Java now runs on more than 3 billion devices.

The main Java Applications 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 many functions that are particularly geared towards the development of graphical interfaces. There are special packages like Abstract Windowing Toolkit, JavaFX, and Swing that help developers put together various GUI components like window windows and toolbars to create smooth and responsive user interfaces. Swing is a bit advanced and includes options for developing progressive GUI elements like trees, tables, tabs, and lists.

2. Applications for Mobiles

Whenever you need to develop Android apps, this is the Goto IDE. Java still has the monopoly of being the most widely used language for mobile application development. It’s even compatible with Kotlin. The reason Java is the language for Android development is that Android apps use Dalvik virtual machines. Java, on the other hand, uses Java Virtual Machines, so it’s easy to develop and package class variables in Java. It becomes completely platform­independent. They are even included in the Android Application Package (APK). Java’s object­oriented principles make it easier and more efficient to develop individual components of an application.

3. Embedded Systems

Electromechanical applications use onboard systems such as microchips and minicomputers to perform dedicated tasks in a system. SIM cards and televisions, still use Java as their building blocks. Java acts as a kernel for TV devices and Blu­Ray disc players.

4.Web Applications of Java

Java is also useful for web development. Java has built­in packages like Servlets, Struts, and JSP. These packets are easy to code and understand at the same time. These technologies also provide high levels of security and allow the development of applications in health, social security, education, etc.

5. Application Servers and web servers

After all, what is an application server? Simply put, it is a framework that assists and provides the development of a server and application environment for the web. It has several components that developers can access through a predefined API for this platform. In Java application servers case, the server operates as an extended virtual machine.

It manages connections to the database on the one hand and the affected web client on the other. Java is also widely used in commercial application services such as WebLogic and WebSphere. However, when we talk about a web server, it is a software/hardware server that responds to client requests on the WWW (World Wide Web). Your task is to register, process, and deliver web pages to clients/users. Communication takes place via an HTTP request.

6. Java Applications for Enterprises

What are companies? Well, put simply, if a company is focused on profit even though it is associated with business ventures, it can be called a business. You can think of a company as any for­profit company. Many companies are now using applications that use Java. For example, Muriel is a high­frequency trading application developed entirely by Java EE (Enterprise Edition). It is responsible for providing runtimes and APIs for running and scripting enterprise software.

7. Scientific Applications of Java

MATLAB is one of the popular scientific applications involving the use of Java. They use Java for both the UI and the mainframe. Why? Because Java has great portability and low maintenance. Therefore, applications are fast, reliable, and can work with a large amount of data. MATLAB is one of the popular scientific applications that use Java.

8. Big Data Technologies

Fast, reliable, and robust, Java is useful for many applications to manipulate and examine big data. With the help of frameworks like Apache Mahout, Apache Spark, Java JFreechart useful for working on big data, Java keeps its place as a valuable language for big data applications. One of the main reasons Java is the base language for many of these technologies is that Java is rooted in open source communities.

9. Business Applications of Java

However, Java EE provides APIs, development models, and runtimes that make it easy to develop these applications. When building business­oriented applications, Java EE Edition is useful for building large, tiered, scalable, and secure network applications. The security and reliability requirements of a business application make them complex.

10. Distributed Applications

Distributed applications are dynamic across the platforms on which they operate. They have several common requirements, like the environment, which is distributed and dynamic. They also need to be equally effective on whatever platform they work on. Furthermore, they support all types of processors, making them versatile. JINI (Java Intelligent Networking Infrastructure) is an indispensable plug­and­play tool. This means that any device connected to a network can immediately provide its services. Distributed services are used by other nodes on the network as needed. Javaspaces is an application that uses this concept. It’s essentially an online bulletin board made up of multiple contributors. It is a repository of objects that can be accessed over the network.
