What is CompletableFuture in Java?

CompletableFuture is a class in Java that allows you to write asynchronous, non-blocking code. It represents a future result of an asynchronous computation.

How does it differ from Future?

Unlike Future, CompletableFuture can be manually completed and allows for chaining multiple asynchronous tasks together.

Can you give me an example of using CompletableFuture?

Sure! Here's a simple example:

CompletableFuture.supplyAsync(() -> {
    // Simulate a long-running task
    return "Hello, World!";
}).thenAccept(result -> {
    System.out.println(result);
});

What are the benefits of using CompletableFuture?

The benefits include better readability, easier error handling, and the ability to combine multiple asynchronous tasks.
