Consuming Streams

Essential Java

A Stream will only be traversed when there is a terminal operation , like count() , collect() or forEach() . Otherwise, no operation on the Stream will be performed. In the following example, no termi...

Using Streams to Implement Mathematical Functions

Essential Java

Stream s, and especially IntStream s, are an elegant way of implementing summation terms (∑). The ranges of the Stream can be used as the bounds of the summation. E.g., Madhava’s approximation of Pi i...
