New Features in Java 8

Java 8 is the biggest change to the Java language ever. The addition of lambdas, functional interfaces, and streams fundamentally changes the programming model for applications. This talk summarizes those changes, along with optionals, method references, and other new features of the language.

Demonstrations will include the map/filter/reduce mechanism, the streaming API, how to write functional interfaces, predicates, suppliers, consumers, method references, default methods in interfaces, optionals, and more.
