Can you explain what Java Futures are?
Java Futures represent the result of an asynchronous computation. They allow you to retrieve the result of a task that may not have completed yet.
What about CompletableFutures? How are they different?
CompletableFutures are an extension of Futures that allow you to manually complete them and provide more flexibility with asynchronous programming.
Can you give me an example of how to use CompletableFutures?
Sure! You can create a CompletableFuture using CompletableFuture.supplyAsync()
to run a task asynchronously and then use methods like thenApply()
to process the result.
What are some common use cases for using Futures in Java?
Common use cases include parallel processing, handling I/O operations, and improving application responsiveness by offloading tasks.
