End your tour of Java's essential language features with
Jeff's introduction to Java 8's method references, interface default and
static methods, and three lesser known language updates that every Java
developer should know about. You'll also preview some interesting additions
coming up in Java 9.
The Essential Java language features tour has explored the
most popular and commonly used features introduced with every version of
Java since JDK 1.4. With this article we come to the end of the journey --
at least for now. Lambdas and functional interfaces are two of the
best-known features added to Java 8, and I covered them in Part 6. In this
article we'll get to know Java 8's contributed method references, interface
default and static methods, as well as type annotations, repeating
annotations, and improvements to generic type inference. We'll complete our
tour with my choice of a few lesser known features that will make a difference
in your programs after Java 9.
