Android is the most common operating system for terminals. Java stands out as the most popular programming language for this platform. It’s also simple to scale up the terminal system owing to its phenomenon of operating – Write Once, Run Anywhere. Java developers can write the Java code just once and can run it on multiple systems.

1.3 Web-Based Applications

Java programming language is capable of building all types of web-based applications with multiple functionalities. It is because of the variety of features that Java offers through its libraries. The multi variance of Java includes frameworks such as Servlets, struts, JSP (Java Server Pages) and JSF (Java Server Faces), Spring, and Hibernate, along with web servers-  such as Apache Tomcat, Apache HTTP web-server, Resin, Adobe JRun, and others. These tools support Java-based web application development. 

Java’s simple coding and excellent security make it possible to create a wide range of applications in the fields of health, social security, education, and insurance.

1.4 Enterprise Applications

The vast capabilities of Java fulfill the criteria for all types of enterprise applications. Thus, the Java programming language has become the primary choice for developing enterprise applications. Today, most corporate firms rely on Java due to its security features, power, and scalability. The Java Enterprise Edition is an API that provides software developers with the tools they need to build enterprise-scale, multi-tiered, scalable, dependable, distributed applications, including web services and secure network applications. Java’s robust memory management capabilities enhance the efficiency of these programs by automatically deallocating unnecessary memory.

1.5 Java Cloud-Based Applications

Cloud-based computing involves processing, managing, and storing data using off-site servers connected to the Internet. The Java cloud-based app operates on a pay-as-you-go model that allows you to replace all in-house local networks with cloud-based infrastructure. Cloud computing is commonly utilized in distributed computer systems. There are many Java cloud development tools available, such as the Oracle Java Cloud Service, which includes Oracle Java and other platforms as development tools for cloud-based applications. You can easily use Oracle WebLogic servers to create full-featured Java-based applications for a specific environment.

1.6 Distributed Applications

When the distribution of applications is dynamic, they are implemented differently. The systems and platforms they operate on have specific common requirements., Java, being one of the leading programming languages, offers various alternatives for developing these apps. Java-powered JINI -Java Intelligent Networking Infrastructure, is a specification-based system that handles the provision, registering, and finding of distributed services. JavaSpaces is a technique that facilitates the distribution and migration of apps within a network. An important feature of Jini is its support for distributed networks.

1.7 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. One of Java’s significant advantages is its ability to 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 is popular for its well-structured nature, excellent data processing, and powerful security features.  This makes it ideal for both traditional banking enterprise applications and cutting-edge FinTech firms.

1.8 Desktop GUI Applications

We can develop desktop GUI applications using Java, which offers support for the Abstract Windowing Toolkit, JavaFX, and Swing for generating the GUI-based desktop application. These tools provide pre-built components such as lists, menus, and buttons.

1.9 Java Web Servers and Application Servers

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

1.10 Game Development

Popular game engines like LibGDX and jMonkeyEngine are written in Java. This makes Java an ideal language for developing games on both desktop and mobile platforms.

1.11 Internet of Things

Many programmers believe that Java is the most suitable language for creating Internet of Things gadgets. This is because it is largely a platform-independent programming language. As a result, you’ll save time because you only need to write your code once for it to run on multiple platforms. 

The fact that it can be utilized for web development, Android development, desktop app development, and more positions it as the greatest option for Internet of Things projects. Compared to other programming languages, Java simplifies the integration of various technologies. Because of this, Java is used in applications like embedded electronics, medical devices, and car navigation systems.

1.12 Artificial Intelligence

Artificial intelligence (AI) and machine learning (ML) applications, especially data monitoring and interpreting tools, are being written in Java. Popular options for creating AI and ML apps include Java frameworks like Apache Spark, Deeplearning4j, and H2O.ai.

2. Why Java?

2.1 Scalability

The system’s capacity is increased by its scalability. By improving the system’s resources, capacity can increase 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, Java applications need to be compiled to operate on all systems. Ensure that JVM is installed in the system. When a Java application is compiled, the Java code is transformed into platform-independent bytecode. The JVM can interpret this bytecode, allowing any computer to execute it.

2.3 Robust API

Java’s Application Programming Interface (API) is extensive, offering many different methods available that can be directly use in any code.

2.4 User-Friendliness

Java offers a language similar to English, making it perfect for newcomers. Core Java can be learned initially, and then more complex Java can be learned afterward.

2.5 Versatility

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

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 handle manually. When the program no longer uses the objects, they are deleted automatically. This enhances the application’s performance.

2.7 Multi-threading

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

3. Companies using Java

Pinterest, Google, Airbnb, Instagram, Spotify, Uber, and Netflix are just a few of the numerous firms that include Java in their technology stack. To assist you choose the best programming language for your next project, we have included a list of companies and ventures they have created.
