Why Java?

Object-oriented

Java allows for the creation of easily maintainable module programs that can be reused in the future.

Active community

The active community of Java users, as well as a wide range of open and free-of-charge sources, allows for the creation of secure solutions in a swift manner. All of that without additional costs related to software development.

Secure

Java is one of the most secure programming languages thanks to its reliable, integrated security functionalities.

Support tailored to your needs

Our teams include Java developers at all skill levels: senior, regular and junior. Regardless of whether you need permanent or temporary support, our Front-End and Back-End developers or DevOps specialists will support your project with their knowledge and competences in the scope and time that you need. This is one of the biggest benefits of outsourcing Java developers and IT professionals.

Multithreading

Software built on Java has the advantage of being able to process multiple tasks simultaneously. This is why the technology can be successfully used to build an application for capturing and processing data, as well as analyzing it.

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.
