Overview

Java 8 Programming for Object Oriented Experienced Developers is a five-day, comprehensive hands-on introduction to Java training course geared for developers who have prior working knowledge of object-oriented programming languages such as C# or C++.  The course covers best practices for writing great object-oriented programs in Java 8 using appropriate development techniques, new features for improved performance and new capabilities for handling rapid application development. The course also involves discussion on a real-world case study that would also serve as a reference for the participants during the course and after its completion.
