More about this course

Our Java 8 New Features training course shows how the language can offer a wide range of new possibilities for software development. While it is easy to learn the basic syntax, effective use of Java requires understanding of the many features of the language. The new features introduced into Java 8 expand the opportunities offered by Java. The introduction of lambda functions and streams support a functional programming style, as well as the traditional object oriented style and related concepts of Inheritance and the role of interfaces.
