  1. Plenty of tutorials and articles cover the most important changes in Java 8 like lambda expressions and functional streams. But furthermore many existing classes have been enhanced in the JDK 8 API with useful features and methods.

    This article covers some of those smaller changes in the Java 8 API - each described with easily understood code samples. Let's take a deeper look into Strings, Numbers, Math and Files.

  2. The Java platform includes a variety of ways to iterate over a collection of objects, including new options based on features introduced in Java 8. In this article John Moore revisits the Iterator design pattern with attention to the difference between active and passive iterators. Learn how Java 8's forEach() method and features of the Stream API can help you fine-tune and parallelize the behavior of Java iterators, then conclude with some performance benchmarks that might surprise you.

  3. The new facilities in Java 8 are about to change the way we write code. Our code will become more expressive and concise. But exactly how?

  4. So far, we’ve been showing the thrilling parts of this new major release. But there are also caveats. Lots of them. Things that

    … are confusing
    … are wrong
    … are omitted (for now)
    … are omitted (for long)

  5. I was reading this interesting post about The Dark Side of Java 8. In it, Lukas Eder, the author, mentions how bad it is that in the JDK 8 the types are not simply called functions. For instance, in a language like C#, there is a set of predefined function types accepting any number of arguments with an optional return type (Func and Action each one going up to 16 parameters of different types T1, T2, T3, …, T16), but in the JDK 8 what we have is a set of different functional interfaces, with different names and different method names, and whose abstract methods represent a subset of well know function signatures (i.e. nullary, unary, binary, ternary, etc).

  6. Brian Goetz describes the future directions for the Java language, especially changes introduced in Java 8, and details the approach taken for key language evolution choices.
