.NET to Java Conversion Training in Finland

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 Finland

Finland is a country located in northern Europe. Helsinki is the capital and largest city of the country. The majority of the people are Finns but there is also a small Lapp population in Lapland, where the country is famous for the Northern Lights. Finland's national languages are Finnish and Swedish.

One of the world's largest sea fortresses Suomenlinna, Rovaniemi with the "White Nights", dogsled safaris and of course the Northern Lights are what makes Finland so popular for tourists. Finland is one of the best places in the world to see the Northern Lights and attracts millions of tourists during its seasons.

Finland is home to a thriving technology industry and is widely recognized as one of the world's leading technology hubs. Companies such as Nokia and Rovio (creator of the popular game Angry Birds) are based in Finland. Some of the key factors that have contributed to Finland's success in technology include; strong investment in research and development, a highly educated workforce and fundings.

Finland has a strong educational system, and is widely regarded as one of the world's most literate countries. In fact, Finland's literacy rate is one of the highest in the world, and its students consistently perform well in international tests of math and reading ability.

Also, as a pioneer in environmental sustainability, Finland is known for its efforts to reduce its carbon footprint and promote clean energy. This Nordic country is also famous for its unique and distinctive cultural heritage, including its traditional folk music and its elaborate traditional costumes.

Helsinki, Finland's capital city, is the country's business center.
