Android is the most common operating system for terminals. Java is one of the most popular programming languages for this platform. It’s also simple to upscale the terminal system owing to its phenomenon operating – Write Once, Run Anywhere. Java Developers can write the code just once and can run it in multiple systems.

2.3 Web-Based Applications

Java is capable of building all types of web-based applications and with multi functionalities. It is because of the variety of features its libraries hold and are capable of offering. The multi variance of java includes frameworks such as Servlets, struts, JSP (Java Server Pages) and JSF (Java Server Faces), Spring, Hibernate, and web-servers such as Apache Tomcat, Apache HTTP web-server, Resin, Adobe JRun, and others. These Java-based functions facilitate the creation of web applications in Java.

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.

2.4 Enterprise Applications

The comprehensive capabilities of Java fulfill the criteria for all types of enterprise applications. Thus Java has become the primary choice for their development. Most corporate firms in today’s world rely on Java applications because it is the most secure, powerful, and scalable language available. The Java Enterprise Edition is an API that gives software developers the tools they need to build enterprise-scale, multi-tiered, scalable, dependable, distributed, including web services and secure network applications. Because Java supports robust memory management, it increases the efficiency of these programs by automatically deleting unnecessary memory.

2.5 Big Data Technologies

Have you heard of Hadoop- an open-source framework for big data? The utilization of Java created the Hadoop open-source framework, which is connected with big data. Many well-known big data technologies, such as Apache Hadoop, Apache Spark, and Apache Mahout, are Java sub-projects.

Java technology is also the foundation for some of the most sophisticated programming languages, or a pure object-oriented language.  Java developers can readily convert programs into other codes and can be used in a variety of applications.

2.6 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 are 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 applications for a specific environment.

2.7 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.

2.8 Programs in Finance Industry
