.NET to Java Conversion Training in Norway

We can host this training at your preferred location. Contact us!

This is a fast paced course for C# coders who are converting to Java / JEE application development. By the end of the course delegates will be able to program using all the features of Java 8 and build server-side infastructure using both JEE specifications (such as JAX-RS and JPA) and popular open source frameworks (such as Spring Boot and JOOQ). There is also a strong focus on continuous testing and deployment via Agile tools such as Gradle, JUnit and Mockito.

Each topic in the course is introduced in terms of the corresponding .NET technology, enabling delegates to leverage their existing skills and make the transition rapidly. The amount of Java language training included depends on the core prevous experience of the delegates. Please note that topics listed below are representative of a typical delivery, but can be tailored based on the projects the delegates will be moving to. For example Hibernate might be substituted for JPA, JEE CDI for Spring Core and JAX-RS for Spring MVC. By default the course uses the Eclipse IDE but alternatives, such as IntelliJ, can be supported if required.

Delegates must be proficient C# or VB .NET developers, ideally with several years commercial programming experience

.NET to Java Conversion Training Course in Norway

The Nordic country Norway, is in Northern Europe. Known for its stunning natural beauty, including fjords, mountains, and forests, Norway is also famous for its high standard of living and strong social welfare system. Norway's capital and largest city is Oslo. Tromsø, Bergen, Trondheim and Stavanger are the other tourist attracting cities of Norway.

Due to the country's high latitude, there are large seasonal variations in daylight. From late May to late July, the sun never completely descends beneath the horizon. Which attracts many tourists around the world to see the "Land of the Midnight Sun". Tourists mainly visit Sognefjord, Norway's Largest Fjord, Pulpit Rock, one of the most photographed sites in Norway and of course the capital; Oslo.
