Learning Concurrency in Kotlin

Obtaining a group of elements

The values can also be retrieved in groups. For example, you can take a group of values at once:

val firstFive = sequence.take(5)println(firstFive.joinToString())

This will print the first five values separated by comma:

Notice that take() is an intermediate operation, so it returns a Sequence<T> that will be actually calculated at a later time—when a terminal operation in invoked. So, in our example, calling take(5) will not actually have the sequence yield the values, but calling joinToString() will.
