Additional Notes
How would you explain a common pitfall when using CompletableFuture for asynchronous tasks in an interview?
Track: Java
Topic: Concurrency
Focus: CompletableFuture
Java: CompletableFuture
Answer
Using blocking calls like.get() on the main thread.
A common mistake is calling.get() on a CompletableFuture, which can block the main thread, negating the benefits of asynchronous execution. Instead, use non-blocking methods like.thenApply() to process results without halting progress. In a web application, blocking the main thread could lead to a poor user experience during high traffic spikes.
