Thread vs CompletableFuture

Question

What is the advantage of passing code directly to thread vs using CompletableFuture instead?

Thread thread = new Thread(() -> {do something});
thread.start()         


        

Answer 1

CompletableFuture is a promise which uses default ForkJoinPool (thread pool of size equal to number of CPU's) unless provided with another ThreadPool. A thread pool will contain n or more number of Thread.
