What Is Java Used For: 12 Real World Java Applications

The language has been the foundation of millions of applications since Sun Microsystems’ development in 1995 and in subsequent years.

Oracle claims about three billion devices use Java for development independent of their platform. Besides these, Java has made its mark also in fields like business solutions and embedded systems.

For Java Classes in Pune, 3RI Technologies have several batches available and versatile timeframes are available to adjust for your current commitments.


Real-World Applications of Java

  •     Desktop GUI Applications

Java language offers a range of features to help us build GUI apps. Java provides the latest foundation classes for JavaFX, AWT, Swing API, or Java. These APIs allow us to create advanced GUI applications that include advanced tree-based applications, including 3D graphical applications.

Java provides web development features, such as Servlets, Struts, Spring, Hibernate, JSPs, respectively., which allow us to develop software with ease.


  •     Mobile Applications

Java language offers J2ME, a cross-platform feature that builds mobile apps that run over Smartphones and feature cell phones provided by Java.

One of Android’s famous mobile systems has been built with Android SDK, Java-based.


  •     Enterprise Applications

Java is the first option for the development of company systems, primarily due to the high performance. Java also makes apps powerful, stable, and easier to scalable, apart from efficiency.

The Java Enterprise Edition framework includes a Java language API and the runtime environment features to write and execute enterprise applications, network tools, and web services.

Almost 97% of the business machines run on Java, according to Oracle. The higher performance and faster computing offered by Java led to the development of most business applications in Java.


  •     Scientific Applications

Java has strong safety and robustness characteristics that make it common to create scientific applications. Java also provides powerful math calculations which give the same results on various platforms.


  •     Embedded Systems

Low-level systems that are part of wider systems are embedded. There are small chips, processors, respectively. And are also known as integrated systems.

Java can generate versatile software that can effectively control application exceptions and quickly boost low-level programming programs.


  •     Server Apps in Financial Industry

Financial companies like banks need different computer software to operate their everyday activities, such as e-commerce systems, settlement writings, validation systems, data processing, etc. Investors need various computer software.

For these tools, Java is primarily used to write server-side apps receiving, processing, and sending data to other servers or processes.


  •     Software Tools

In Java have been written several app developments tools. IDEs like Eclipse and Concept are both written and built-in Java, for example.

These are currently also the most common GUI-based desktop applications. Earlier swing and AWT mainly use to develop applications, but today, JavaFx is more common.


  •     Trading Applications

Java is the famous Murex trading application used for front-to-bank connections in many banks.


  •     J2ME Apps

In addition to iOS and Android smartphones, Nokia and Samsung phones use J2ME, and In products like Blu-rays, cards, set-top boxes, etc., J2ME is also popular. The famous WhatsApp application available in Nokia is J2ME.


  •     Big Data Technologies

Big data is now the subject of the most common trends in the field of computing. Big data is used to evaluate and consistently extract insights from diverse data sets.

An open platform linked to large data is called Hadoop, and it is written in Java entirely. Java takes the edge over other technologies with such features as automated waste pick-up, memory distribution, and stack provision system. 


  •     Most common frameworks for Java

Frameworks are tools used in the development of applications. A system is designed to ease the developer’s life and make it possible for developers to concentrate on industry logic rather than code jargon.

The selection development environment depends on our method. If an application needs a great deal of UI architecture, we can choose a platform that offers rich UI developer tools and APIs.


  •     Cloud-based Applications

Cloud computing involves providing on-demand IT resources via the Internet, including storage services, servers, databases, networks, or pricing-as-you-go applications. It offers a low-cost IT infrastructure solution to save and download files from remote databases on demand.

Java is the mobile apps programming language long ago, and now, due to its distributed architecture, it has reached cloud applications.

Java offers the features to build SaaS (Software for Service), IaaS (Infrastructure as a Service), and PaaS (Platform-as-a-Service) applications for development.

A lot of cloud development tools are accessible to Java. For example, Oracle Cloud Java offers a portal for Oracle server development and setup. Java can help companies remotely create their software or exchange data with others according to their needs.
