Streams which provide lazy iteration of values, either from a collection, from an infinite series (such as ThreadLocalRandom) or from a fixed range (such as produced by IntStream).An example would be Integer::parseInt, which could be mapped to a collection of Strings to produce a collection of Integers. Method References allow a static method to be referred to as a function that can be passed into a function.(Note that the reason they are called lambdas is that Java has had closures in the form of inner classes since Java 1.1 what some incorrectly refer to as closures are really talking lambdas.) An example of a lambda is x -> x +1. With implicit casting to Single Abstract Method types (such as Runnable) it will dramatically simplify code that needs to pass filters and other predicates as data. Lambdas provide a means to pass functions as data.Java 8 ships with a number of improvements and new features. There is also a package specifically for ARM (compiled for the Hard Float ABI) which can be used on Raspbian and other Raspberry Pi platforms. Downloads are available for Linux and Windows as 32- or 64-bit packages, along with Mac OSX and Solaris 64-bit packages. Today at EclipseCon, Oracle announced the general availability of Java 8, the first major upgrade in over two years.
