Have you dealt with using CompletableFuture for asynchronous task processing?

Yes, I have used CompletableFuture for asynchronous task processing in Java. This class allows executing operations in a separate thread and handling the result upon completion without blocking the main thread.

Example of usage:

CompletableFuture.supplyAsync(() -> {
    // Long operation, such as a request to a remote service
    return fetchData();
}).thenAccept(data -> {
    // Processing the result
    System.out.println("Data received: " + data);
});

This approach helps improve application responsiveness and efficiently utilize resources, especially in web applications or when working with I/O operations. CompletableFuture also supports combining multiple asynchronous tasks and error handling.
