How do you break a Monolith into Microservices at Scale? This ebook shows strategies and techniques for building scalable and resilient microservices.

Here’s the latest publication by Brian Goetz, Oracle’s project lead for JSR 335, a.k.a. Project Lambda. Here’s a nice example showing new collection features, such as “Streams” using method references:

List<String> strings = ...
int sumOfLengths = strings.stream()
                          .map(String::length)
                          .reduce(0, Integer::plus);

Another nice example showing the use of lambda expressions:

int sum = shapes.stream()
                .filter(s -> s.getColor() == BLUE)
                .map(s -> s.getWeight())
                .sum();
