According to most individuals, Java is the most common programming language today because several devices are running on a Java platform. But What are the best uses of java? What are the features of Java? You will get answers to all your questions as you continue reading this blog. Java is involved in almost every field of software development. Because of its features, this is one of the most powerful languages in the modern market of software development used by almost every field.

Moreover, it is an object-oriented language that supports all the object-oriented programming language features. It is the most reliable language in the modern world because banking development applications occur in Java only. Another reason why Java programming language is best is because it is very easy to learn. It supports multithreading also which benefits the development of games. The distributed application is also easily developed with the help of Java. Many Java frameworks offer it in modern times, making it more powerful like Servlet, Spring, JSP, hibernate, spring Boot. Below we will be listing down all the main uses of Java real-world, but before that, let us know a little bit about this language and it’s features first.

What is the Java?

Java is a computer programming language utilized for general purposes and it is object-oriented, concurrent, and class-based. By James Gosling it was developed in 1995 at Sun Microsystems, the organization later acquired by Oracle in 2009. The language is made so that developers can run it on all platforms that support Java without requiring it to be recompiled. This programming language is extensively used for developing Java applications in laptops, game consoles, data centers, cell phones, scientific supercomputers, etc.

Some features of Java

Some of the basic Java features are:

· Java is highly Robust and Very Secure

· This represents an instance of a class like encapsulation, abstraction inheritance, polymorphism.

· It writes code only once and runs it on almost every computer platform.

· Java is extensively used for object-oriented application development.

· Java is easy to understand. It has no complication in its features like an inheritance, pointer, operator overloading, etc.

· Java is a multithreaded language with automated memory management.

Why is Java Important?

It is hard to give a particular reason why the Java programming language is so important in the modern world. Currently the number of Java developers is over 9 million worldwide. The world is in a continuous race to grow and we require it to keep up. Because of its great features and interesting real-world applications, Java is being taught as an introductory language to programming. The programmers who have in-depth knowledge of Java programming language, have high demand in the market today. Here are some of the reasons why is Java important:

· Java’s Popularity and High Salary

· It is Easy to Learn

· This language has a large community

· Java has an abundant API

· It has Powerful Development Tools

· Java has multiple Open-Source Libraries

· It is Platform Independent

Top 11 Real World Uses of Java

1] Development of Scientific Application

Java helps in the development of scientific applications, because of its robustness and security features. Many scientific applications are Java technology-based like MATLAB. The applications which are related to medicine, science, and research are also developed in Java. It has great mathematical calculation which gives identical results on several platforms, this makes it the best selection for the application development.

2] Desktop GUI Application:

The desktop application can simply develop in Java, to help this Java gives AWT, JavaFX, and Swings. The swing is based on Java means completely Java-based development can be done with the help of Java Swings package. JavaFX is a new way to develop a desktop application. It is based on graphs and different from a swing and AWT. With the help of these frameworks and packaged, any type of application can be quickly developed. NetBeans IDE also gives drop and drag features in, So the development of UI can be completed within a short time.

3] Development of Web Applications

Other uses of Java are for web application development. Java provides support for web applications through Servlet, JSP, Struts, hibernate, Spring. With the help of the technologies, based on customer demands, we can efficiently develop web applications. JSP and Servlet, the server-side components that help web application business logic development, JSP is a servlet extension with added features. JSP is easy to use as compared to Servlet because of tags like in HTML. These are the main Java components that help web-based application development.

4] Mobile Applications

J2ME or Java ME is a cross-platform framework to make applications that run over all devices that are Java supported, including smartphones. With the help of Java one can easily develop mobile applications. In the modern world, every second phone you see either using android or an OS which is based on Java. We can develop any kind of application and any type of game in android easily. Android is completely Java-based.

5] Enterprise Applications development

For the development of Enterprise applications Java is the primary choice because of it’s great features that match the needs. In the modern world, most of the project site is based on Java applications only because it is most scalable, powerful and secure. Java can fulfill all the requirements because sites need too much security. Java has powerful memory management features. It automatically deletes the unnecessary memory which increases the performance of the large application. Java applications can easily be scalable in case of an increase of users on the program application site. It is the most reliable language and because of that reason many banking applications are produced on Java platforms.

6] Application Servers and Web Servers

The Java ecosystem today includes many application servers and Java web servers. While Project Jigsaw, Jo!, Apache Tomcat, Rimfaxe Web Server (RWS), and Project Jigsaw control the web server space. JBoss EAP, WebSphere, and WebLogic dominate business application server space.

7] Gaming Applications

Java has the support of the open-source most powerful 3D-Engine, the jMonkeyEngine that has the unparalleled capability when it comes to the designing of 3D games. However, it does cause an occasional latency issue for games as garbage collection. cycles can cause noticeable pauses. This issue will be solved in the newer versions of JVMs.

8] Big Data technologies

Java is the reason why the leading Big Data technologies like Hadoop have become a reality and also the most powerful programming languages like Scala are existing. It is crystal clear that Java is the backbone when it comes to developing Big data using Java.

9] Business Applications

Java EE platform is designed to help developers create large-scale, multi-tiered, scalable, reliable, and secure network applications. These applications are designed to solve the problems encountered by large enterprises. The features that make enterprise applications powerful, like security and reliability, often make these applications complex. The Java EE platform reduces the complexity of enterprise application development by providing a development model, API, and runtime environment that allow developers to concentrate on functionality.

10] Distributed Applications

Distributed applications have several common requirements that arise specifically because of their distributed nature and of the dynamic nature of the system and platforms they operate on. java offers options to realize these applications. The Jini (Java Intelligent Networking Infrastructure) represents an infrastructure to provide, register, and find distributed services based on its specification. One integral part of Jini is JavaSpaces, a mechanism that supports distribution, persistence, and migration of objects in a network.

11] Cloud-Based Applications:

Cloud computing means on-demand delivery of IT resources via the internet with pay-as-you-go pricing. It provides a solution for IT infrastructure at a low cost. Java provides you with features that can help you build applications meaning that it can be used in the SaaS, IaaS and PaaS development. It can serve the companies to build their applications remotely or help companies share data with others, whatever the requirement.
