Description

Java has been significantly changed in version 8. Many long-planned features were introduced in the language, making it more functional. Using these features requires new approaches to programming and a deep understanding of new principles.

This training is designed to help participants understand the new features of Java 8. The course covers lambda expressions, data streams, stream data processing with map-filter-reduce approach, asynchronous programming and DateTime API. Every key area has a number of practical exercises that allows participants to practice what they learned.
After completing the course, a certificate
is issued on the Luxoft Training form

Objectives

To introduce developers to the features in Java 8.
