In 2022, the top 15 most popular Java applications will be used all over the world.

This year marks the 25th anniversary of Java, and despite the emergence of many newer and flashier languages and tools, it remains one of the most popular programming languages. The old lad keeps chugging along, grateful for the affection of so many programmers and developers today. According to Oracle, which bought Sun Microsystems, the inventor of Java, in 2010, Java can be found on over three billion devices.

Java’s success is largely due to these four characteristics:

·         Because Java is platform-agnostic, a programmer may build code for one operating system and run it on another (or the same one)

·         Java is a class-based object-oriented programming language. Everything in Java is treated as an object, and those objects, in turn, accomplish all of the programmed development tasks.

·         Unlike other programming languages, Java is simple to pick up.

·         Many processes can run code at the same time, allowing for the execution of multiple Java programming statements in parallel rather than sequentially.

These benefits, together with its widespread use, explain why this old (at least in the digital world!) language has maintained its appeal. As a result, it’s no wonder that Java applications may be found in a wide range of settings and sectors.

Java Applications

1. Java Mobile Applications

Let’s start by noting that the Android operating system is heavily based on Java, and that Android phones routinely have a market share of more than 85%. Add in the fact that the majority of mobile app developers use Java as their primary programming language. Java is compatible with app development software such as Kotlin and Android Studio. Java Platform, Micro Edition (J2ME) is a cross-platform framework for designing programmed that operate on all Java-enabled devices. When you consider all of this, as well as the fact that mobile computing is now exceeding desktop computing, it’s clear that you won’t be able to avoid Java.

2. Java Desktop GUI Applications

GUI stands for Graphic User Interface, and Java provides resources like Abstract Windowing Toolkit (AWT), JavaFX, and Swing to enable GUI creation. AWT includes a number of pre-made components, such as buttons, lists, and menus, as well as a number of third-party components. Swing interoperability and 3D graphics features are provided by JavaFX, which is made up of a series of graphics and media packages. Swing is a graphical user interface widget that includes sophisticated features including lists, scroll panes, tables, tabbed panels, and trees.

Even though mobile computing currently dominates the market, there is still a demand for desktop apps, and programmers may create any desktop application using these technologies.

3. Java Web-based Applications

Java is popular among web application developers because of its excellent security and easy coding. Servlets, Struts, and JSPs provide effective web application support and the ability to construct any type of software required. Additionally, open-source e-commerce platforms like Broadleaf make developing e-commerce apps simple.

4. Java Web Servers and Application Servers

Numerous Java web and application servers have sprung up as a result of the powerful Java ecosystem. Servlets such as Apache Tomcat, Project Jigsaw, and Rimfaxe Web Server are found on web servers (RWS). In the meanwhile, servlets like as WebLogic, WebSphere, and JBoss EAP have a strong presence in the commercial application server market.

5. Java Enterprise Applications

Java Enterprise Edition (Java EE) is a popular platform that provides APIs and runtime environments for scripting activities such as web services and network applications. According to Oracle, Java is installed on 97 percent of corporate PCs. Java is also known for providing the backbone for many banking apps, which use it throughout the process, from front-end users through back-end servers. Finally, Java’s ability to maintain high performance makes it an ideal platform for high-frequency trading systems such as Murex.

6. Java Scientific Applications

Mathematical operations and computations in science need the creation of apps that are incredibly quick, secure, easy to maintain, and portable. Java is an excellent fit for this need. Java is used as part of the core system and interactive user interfaces in powerful scientific programmed like MATLAB.

7. Java Gaming Applications

Java and the gaming industry are a wonderful match. The jMonkey engine, one of the most powerful 3D engines available today, is supported by Java. 2D games are also simple to make; simply combine Java with CSS and you’re set to go. So, regardless of the type of game that developers are creating, Java has them covered.

8. Java Big Data Technologies

Big data is all the rage these days, and it’s no surprise that Java is right in the middle of it. First and foremost, Hadoop, undoubtedly the most well-known and widely used big data platform, is developed in Java. Scala, a competitive programming language, is also descended from Java. Scala was established in response to some of Java’s flaws.

In the area of Big Data, four programming languages fight for the title of finest and most widely used: Java, Scala, R, and Python.

9. Java Business Applications

Big businesses have a lot of issues. That’s why these companies choose the Java EE platform to build scalable, dependable, and secure large-scale, multi-tiered network applications. By offering tools like a development model, API, and runtime environment, Java can produce strong software that is less difficult. These functions allow developers to focus on the app’s functionality.

10. Java Distributed Applications

Programs that operate on numerous computers connected to the same network are known as distributed apps. Internet Explorer, for example, is a distributed programmed. These programmed are divided into two groups: client software and server software.

Because of their dispersed nature and the changeable quality of the servers and systems that operate them, distributed apps pose particular issues. JINI, or Java Intelligent Networking Infrastructure, is a network infrastructure that delivers, registers, and locates distributed services based on their requirements. JavaSpaces is a JINI component that helps with network distribution, persistence, and object migration.

11. Java Cloud-based Applications

Most IT experts would say “Big Data, the Internet of Things (IoT), and cloud computing” when asked what the three most essential parts of today’s digital environment are. It’s hardly surprising; therefore, that Java has made its way into the cloud.

Cloud computing is described as the processing, management, and storage of data utilizing off-site servers connected to the internet. It’s a pay-as-you-go approach that takes the role of in-house local networks. For distributed computer systems, cloud computing is frequently employed.

The Oracle Java Cloud Service is one of several Java Cloud development tools available. It serves as a platform for installing and configuring Oracle WebLogic servers and their related application environments fast and easily.

12. Software Tools

Developers utilize software tools, also known as software development tools, to create, debug, and manage other software programmed and applications. Many software tools are written in Java. Netbeans, IntelliJ IDEA, and Eclipse, for example, are all Java-based integrated development environments.

13. Embedded Systems

Low-level systems that are generally a component of larger electromechanical systems are referred to as embedded systems. Processors, small chips, microcontrollers, and other devices fall under this category. Java is used to create low-level embedded systems that are both reliable and quick. Popular embedded systems that may be created in Java include Blu-ray discs and SIM cards.

14. Trading Applications

Java is also utilized to create high-security trading apps. Murex is one of the most widely used trading software for risk, treasury, and post-trade processes in financial markets by banks. It’s written in the Java programming language.

15. J2ME Apps

Apple’s iOS and Google’s Android are the most popular mobile operating systems today. However, J2ME is used by a variety of cell phones and personal digital assistants (Java 2 Platform, Micro Edition). J2ME is widely utilized in the development of devices such as blu-ray discs, set-top boxes, and cards. In the coming years, J2ME applications are projected to grow in popularity.
