What is asynchronous programming Kotlin?

CompletableFuture is inherently thread-safe The methods of all classes in java. util. concurrent and its subpackages extend these guarantees to higher-level synchronization.

Kotlin’s approach to working with asynchronous code is using coroutines, which is the idea of suspendable computations, i.e. the idea that a function can suspend its execution at some point and resume later on .

A CompletableFuture is an extension to Java’s Future API which was introduced in Java 8 . A Future is used for asynchronous Programming. It provides two methods, isDone() and get(). The methods retrieve the result of the computation when it completes.

The CompletableFuture. get() method is blocking . It waits until the Future is completed and returns the result after its completion.
