Java: Asynchronous HTTP
Answer
Waiting for multiple asynchronous tasks to complete.
CompletableFuture.allOf is used when you need to wait for multiple asynchronous tasks to complete before proceeding. For example, in an e-commerce application, you might need to gather product availability data from multiple warehouse APIs before calculating the total stock. allOf ensures all data is collected before any further processing is done.
