The next major language extension (after generics in Java 5) will be lambda expressions in Java 8.  They add elements of functional programming to Java and have the potential to change the way we express ourselves in Java.  They were designed primarily for use with the JDK's overhauled collection framework and its new stream API.  In this session, however, we want to explore how we can benefit from using lambdas in other situations (independently of streams) as well.  Lambda expressions can help expressing idioms that were clumsy to use in lambda-less Java.  We will use a couple of examples to illustrate the benefits and limitations of Lambda expressions in Java 8.
