Introduction to the Java ExecutorService YouTube

I have created a custom ExecutorService. ExecutorService executor = new ThreadPoolExecutor (0, maxPoolSize, keepAliveTime, timeUnit, new LinkedBlockingDeque<> ()); to which I submit my tasks. Future result = executor.submit ( () -> "test"); As you can see, the executor returns a meager Future; I'd much rather have a CompletableFuture.

3. Using completeOnTimeout () The completeOnTimeout () method resolves the CompletableFuture with a default value if the task doesn't finish within the specified time. With this method, we can set the default value to return when a timeout occurs. This method returns the CompletableFuture on which this method is invoked.

Advanced Java CompletableFuture Features Introducing Completion Stage Methods YouTube

CompletableFuture. CompletableFuture is a powerful and flexible concurrency API introduced in Java 8 that combines the best features of the Future and Promise APIs. It provides a non-blocking, fluent API for chaining multiple asynchronous operations, and it can be used in combination with the Executor framework for greater control over the.

Applying Basic Java CompletableFuture Features YouTube

Let's explore how we can take advantage of asynchronous operations from ExecutorService and CompletableFuture to run tasks in parallel. 1. Create ExecutorService #. Let's first create a new thread pool that reuses some fixed number of threads. ExecutorService executorService = Executors.newFixedThreadPool(10);

Java ExecutorService Using Virtual Threads YouTube

2.1. Factory Methods of the Executors Class. The easiest way to create ExecutorService is to use one of the factory methods of the Executors class. For example, the following line of code will create a thread pool with 10 threads: ExecutorService executor = Executors.newFixedThreadPool ( 10 );

Java ExecutorService example using Callable and Future Java2Blog

Why was CompletableFuture introduced in Java 8 when you already had the Future interface? A5. The CompletableFuture implement both CompletionStage and Future interfaces. Hence it provides the functionality of the Future interface in terms of getting the result, cance;ling a task, and determining if a task is completed or cancelled, etc.

CompletableFuture is a class in java.util.concurrent package that implements the Future and CompletionStage Interface. It represents a future result of an asynchronous computation. It can be thought of as a container that holds the result of an asynchronous operation that is being executed in a different thread.

1. I have tried complex usecases which can be done by CompletableFuture can be done by ExecutorService as well. That includes, handling exceptions as well. The only difference I can see between them is, CompletableFuture gives better readability and convenience during coding. Is there any practical advantage / use-case that one can solve using.
