As you may already know, Java's Stream API is one of the most significant features introduced in the latest platform version. Aside from the lambdas, which can reduce the amount of boilerplate code in our code base, the Stream API releases us from the burden to be responsible for how collections are traversed, for example. In the pre-Java8 platform versions, we could either use an implementation...

The day began by co-presenting a session with Heather...
