Typical usage of Java programming language

Android is a Java-based platform, which makes Java one of the most commonly used programming languages, allowing for the development of mobile applications. Moreover, Java frameworks, such as FX and Swing, are used to create graphical interfaces in desktop applications. Java is also used while creating websites, wherein popular frameworks are Spring Boot (including Spring MVC) and JSF.

Spring Data Repository is used in order to develop the back-end of an application. It facilitates access to data gathered in both SQL and non-SQL databases. There is a wide range of available Java programming tools facilitating and expediting project development – including integrated programming tools (such as: Intellij IDEA and Eclipse), software development automation tools (Maven, Gradle), continuous integration tools (i.e. Jenkins and Bamboo) or version control systems, i.e. Git or SVN.
