Vaadin has been enabling Java development teams to build enterprise-grade web apps in Java for over twenty years. The Vaadin framework is unique, as it is the only one that allows developers to build modern web apps completely in Java, without any browser plugins. 

For well over two decades, Java has ruled the programming stage as one of the go-to languages for developing robust, scalable enterprise applications. Unlike other programming languages whose presence and usability have come and gone, Java has become stronger with each update and release.

Read on for a brief overview of Java, what makes it a popular choice amongst enterprise app developers and how the Vaadin platform enables developers to build entire web apps in Java. 

What is Java?

At its simplest, Java is a robust, object-oriented programming language and computing platform, first released in 1995 by Sun Microsystems. A multitude of applications and websites rely on Java in order to function.

Java is used for everything from desktop and mobile computing, games and modern PWAs to self-driving cars. Throughout the years, Java has consistently evolved and undergone exhaustive testing and updating.

It has gathered a dedicated community of developers, architects and enthusiasts, thus creating a stronghold within the realm of business web app development.

Java for enterprise web apps

The Java programming language is popular not only for developing small apps, but also for large, end-to-end enterprise software. Companies build large-scale enterprise software in Java in order to improve the operation of their businesses and gain a competitive edge. 

A few of the capabilities making the language an appropriate choice for business web app developers include the following:

  • Stability - Java has ruled the industry since the 90s, when it became the default language for most enterprises, due to its flexible integration and independent code. 
  • Supports a variety of libraries - Libraries are collections of prewritten code made available for developers. They are the building blocks for enterprise apps, and Java supports millions of libraries and codes, making for a smoother development process.
  • Scalability and compatibility -  Java is highly scalable, making it suitable for providing and managing enterprise-scale development and workloads. In addition, thanks to the Java Virtual Machine (JVM), applications written in Java are highly compatible with existing platforms, such as macOS, Unix, and Windows.
