What is Java Used for in Today's Programming?


Java has been here for a while now, which poses question what is Java used for today. Is this programming language still relevant?

The answer is yes, and the reason is safety.

When working, building, creating, or simply unwinding and relaxing – any online activity should take place inside a safe environment. Java software is a renowned software that operates virtually anything, and everything in the digital sphere.

Equipment of all sizes make use of Java. This ranges from laptops, to data centers, to game consoles, to scientific supercomputers.

But before I get into the details. Perhaps I should answer the pressing question of exactly.

What is Java?

It is a free-to-use programming language that’s also open source. In any case, it’s a widely used language, that’s designed for use in the distributed environment of the internet. Additionally, it’s made with the look and feel of the C ++ programming language. Lastly, it’s worth mentioning that it enforces an object-oriented programming model.

Java is also particularly known for its role in creating applications. The versatility of it mean you are able to build apps that run on a single computer, or one that can be distributed across multiple servers and clients within a network. They are also commonly found as a small application module. These are also referred to as Applets. These segments form part of a webpage. Though, this is now considered a legacy technology.

Who is Using Java?

It’s popular, to say the least. Java plays a significant role in everyone’s digital life, from web page, to television screen.

In total, the number of mobile phones running Java is 3 billion. Java is also considerably popular in the development of Android smartphone apps. Its base of enterprise desktops takes a decisive share, however. In total, approximately 97% of Enterprise Desktops run Java. In the US, 89% of Desktops or Computers in the U.S run the programming language.

Beyond Traditional Devices

In total, there are over 5 billion Java Cards in use. This extends beyond the realm of computers and mobile devices. 125 million television devices run Java.

Meanwhile, Java continues to be the most used development platform. the number of Java developers, worldwide, numbers 9 million.

Open Source Projects

In all, there are many open source projects that let developers create efficient applications. Many open source projects engage in building MVC applications, database connectors, as well as messaging connectors.

It is also worth noting the Graal and GraalVM projects. These are a new approach for running Java-based applications – also known as AOT.

The Benefits of Java

It’s a popular tool, and for a variety of reasons. From the inherent benefits, to the after-effects. I’d like to take you through some of its merits. Firstly, this language is simple for even novel developers. Java is quick to learn, making this a highly logical choice.

Java runs on JVM. This essentially means it provides many developer-friendly mechanisms. Some of these include Code Optimisation, Memory Management, as well as the Garbage Collector function. Of course, you’re not going to be restricted purely to Java. You can also develop code through a number of methods. Those include Groovy, Scala, and Kotlin, which can run on JVM.

In age of constant improvement and upgrades, Java is ahead of the curve. In recent years, this tool has made frequent new version releases. Today, Java upgrades come very often. This shows that Java is trying to remain close to developers. In turn, this helps release some functionalities for the purpose of receiving feedback. Ultimately, each subsequent product gets developers’ feedback, to help improve the product in its next version release.

Another series of benefits are the tool’s portability in a network. It is also a notably, object-oriented tool with a highly robust code. Security is an additional merit, as it ensures secure data.

The Drawbacks

From what I can gather, there are some reasons people can have reservations to Java. While it is simple to learn, it does still posses something of a learning curve. Some jargon is common, that might go over the head of some novel users.

In these cases, where the syntax is too complex, it is worth taking a refresher course. Thankfully, there is a great deal of community support for Java. Even a series of articles or YouTube videos could prove helpful as well.

What is Java Used for? Potential Areas for Expansion

PC and Mobile are widely explored domains of our time. But where else would a programmer wish to extend their reach?

Earlier, I had mentioned the emergence of television platforms. With the onset of Smart Televisions, the use of Java can expect a commanding presence.

However, areas with the most significant potential include Industry 4.0 technologies. Here, Java can expect to play a significant role in building of IoT infrastructure, as well as edge systems.

In all, use Java for anything that could suit your next digital project. With this highly-functional programming language, you can engage in boundless projects. Enjoy extensive support, and make use of a stunning list of functionalities.

With Java, you, and your next ambitious venture stand to make its mark on the world. Get building now!
