Fast Track to Java 8 Training in Finland

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

Java 8 is the most important update to Java since its inception. The limits of the existing language have been exposed by the challenge of multi-core hardware, the industry adoption of functional principles, the continued evolution of C# and the growing adoption of alternative JVM languages like Scala and Clojure.

This new release of Java aims to address these concerns via new language features, enhancements to existing libraries and numerous low level improvements to the JVM itself. Developers can use these enhancements to write shorter, safer applications that are amenable to multi-core devices.

This course enables experienced Java developers to understand the full range of features arriving in Java 8 and to start using them immediately.

Delegates must be proficient in Java 7 with several years of experience developing in industry.

Fast Track to Java 8 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.

Known for its vast forests, lakes, and natural beauty, Finland is one of the world's largest producers of forest products, such as paper, pulp, and lumber. 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. Helsinki is Finland's largest city, and it is home to many of the country's major corporations and organizations, including many of the country's leading technology firms. The city is also a commercial, trade, and financial center, as well as one of the busiest ports in the Nordic region.
