If you go by statistics, Java has been backing up multiple applications by providing a variety of tools, enhancements and consistent support from the software development community. Thus, there is no hesitance in using Java for real-world applications. Since Java has been structured in a way that it can be used by anyone and anywhere, in the market there are many examples of using Java for real-world applications. In this blog, we will be seeing how Java has been acting impactful for all other applications.

1. Uses of Java in the Real World!

Java language is a game-changing language for multiple businesses and has been a part of the success of many leading enterprises. Businesses know that Java has been a backbone during the process of development of Macintosh, Windows, and even UNIX-based systems. Also, from a commercial point of view, everything from e-commerce websites to android apps, from scientific applications to financial applications like electronic trading systems- Java is everywhere. From games like Minecraft to desktop applications like Eclipse, Netbeans, and IntelliJ. From an open-source library to J2ME apps, Java programming language is used in many places in the real world. Let’s take a closer look at each of them.

uses of Java

1.1 Android Apps

Android currently holds roughly 87% of the worldwide market share for mobile devices.- Statista

When it comes to mobile phones, Android, which is based on Java, is the most popular.

1.6 Java Cloud-Based Applications

Java has not surprised us by integrating one more system into it. Cloud-based computing is a method of processing, management, and storage of data utilizing off-site servers connected to the internet. The Java cloud-based app is a pay-as-you-go model that allows you to replace all in-house local networks with cloud-based links. For distributed computer systems, you can employ cloud computing quite frequently. There are many Java Cloud development tools available such as the Oracle Java Cloud Service, including Oracle Java and other platforms serving as developing platforms for cloud-based applications. You can easily use Oracle WebLogic servers to create apps with full-featured java applications for a specific environment.

1.7 Distributed Applications

When the distribution of applications is dynamic in nature, they provide a different way of implementation. The nature of the systems and platforms on which they operate, distributed applications have certain common needs. Java being one of the leading provides a number of alternatives for implementing these apps. Java-powered JINI -Java Intelligent Networking Infrastructure is a specification-based infrastructure for providing, registering, and finding distributed services. JavaSpaces is a technique that facilitates the distribution and migration of apps in a network. The key to distributed networks is an important feature of Jini.

1.8 Programs in Finance Industry

In the financial sector, Java has long been the go-to software development option, and many successful banking applications and solutions are still used. Java has a significant advantage over competing technologies in that it can run on any device. Java runs in a virtual environment that can launch the software from any location and uses the same code.

It has been a long time since the banking, finance, and insurance firms have utilized Java to develop their computing platforms. Java as a programming language is well-structured, and allows good data processing, with built-in security measures, making it ideal for both traditional banking enterprise applications and new-edge FinTech firms.

why is java so popular in banking industry?

1.9 Desktop GUI Applications

We can produce Desktop GUI applications utilising Java. Java renders Abstract Windowing Toolkit, JavaFX, and Swing for generating the GUI based desktop application. The tools include the pre-assembled components such as the list, menu, and button.

1.10 Java Mobile Applications

Android OS is almost based on Java, and Android mobile consistently earns a market share of 87%. It is considered as the fact that most mobile app developers describe Java as their official programming language. Java is harmonious with app designing software like Kotlin and Android Studio. Java Platform, Micro Edition (also known as Java ME or J2ME) operates as a cross-platform framework for building mobile applications that run over every Java-support device.

1.11 Java Web Servers and Application Servers

The strong Core Java ecosystem has provided growth to various Java web application servers. Web server space is a place for servlets such as Apache Tomcat, Project Jigsaw, and Rimfaxe Web Server (RWS). Meanwhile, servlets such as WebLogic, WebSphere, and JBoss EAP have a strong niche in the commercial application server space.

1.12 Game Development

2. Why Java?

Why Java?

2.1 Scalability

The system’s capacity is increased by its scalability. Improving the system’s resources increases capacity without changing the deployment design. Scalability can be achieved by adding more resources to a single system, such as more memory or a faster processor. Its significance lies in the fact that it distributes work, boosts system performance, and maximizes output.

2.2 Cross-Platform

To be cross-platform, a Java application must be compiled to operate on all systems. Ensure that JVM must be present in the system. When a Java application is compiled, the Java code is transformed into platform-independent bytecode. The JVM can interpret this bytecode. Any computer can execute this bytecode.

2.3 Robust API

Despite having only fifty keywords, Java’s Application Programming Interface (API) is extensive, with many different methods available for direct usage in any code.

2.4 User-Friendliness

Java offers an English-like language, making it perfect for newcomers. Core Java can be learned initially, and then more complex Java can be learned afterwards.

2.5 Versatility

Java has been the standard language for developing websites, mobile apps, and IDEs (integrated development environments) for a long time now.

2.6 Memory-Management

Garbage collection is the method that Java uses to manage memory. Memory management is not something we should worry about or execute. When the program is no longer using the objects, they are deleted automatically. The application’s performance is enhanced.

2.7 Multi-threading

A thread is a relatively lightweight subprocess. With Java’s multithreading capabilities, many threads may run in parallel. It makes the most efficient use of the processor.

3. Companies using Java

Pinterest, Google, Airbnb, Instagram, Spotify, Uber, and Netflix are just a few of the numerous firms that employ Java as part of their technology stack. In order to assist you choose the finest programming language for your next project, we have included a list of companies and ventures. they have created.
