modernfeatures.concurrency.CompletableFutureBasicsExample

public class CompletableFutureBasicsExample
extends Object

Demonstrates basic usage of CompletableFuture for asynchronous programming in Java 8+.

• Run asynchronous tasks that return a result using CompletableFuture.supplyAsync().
• Run asynchronous tasks without a result using CompletableFuture.runAsync().
• Block and wait for asynchronous computations to complete using get().

Example usage:

 
 CompletableFuture<String> future = CompletableFuture.supplyAsync(() -> {
     // Long-running computation
     Thread.sleep(10000);
     return "Hello from CompletableFuture!";
 });
 String result = future.get();
 System.out.println("Result: " + result);

Method Details

main

public static void main(String[] args)
                 throws ExecutionException,
InterruptedException

Main method demonstrating basic CompletableFuture usage.

• Starts an asynchronous task that returns a result.
• Starts an asynchronous task without a result.
• Blocks the main thread to wait for completion of both tasks.

Parameters:

args - command line arguments (not used)

Throws:

ExecutionException - if the computation threw an exception

InterruptedException - if the current thread was interrupted while waiting
