Lesson 12 - Multithreading in Java - CompletableFuture
In the previous lesson, Multithreading in Java - ForkJoinPool, we talked about
ForkJoinPool. In this lesson, we're going to learn what is in my
opinion the best class for parallel programming offered by the basic Java
Concurrency framework -
A few lessons back, we introduced different interfaces related to parallel
Future. The interfaces are ordered according to the increasing
functionality. We described the
Future interface as an object that
will contain the result of a task sometime in the future. The problem with this
interface is that we don't know when the result will be available. The only way
to get the result is to use the blocking
method, which blocks the thread in which it's called. The developers tried to
solve this problem by using the
CompletableFuture class and I must
say that they did great. Let's introduce
The class implements two interfaces:
