Java: Non-Blocking I/O (Event Loops)
Answer
An event loop that doesn't wait for tasks to complete.
A non-blocking event loop allows a program to handle multiple tasks by delegating blocking operations like database queries to other threads. This keeps the main loop free to handle incoming events. For instance, in an e-commerce platform using Spring WebFlux, when a customer checks the price of an item, the event loop can instantly return to handle another request while the database query is processed asynchronously.
