Guide to CompletableFuture join() vs get()

In Java's concurrent programming, CompletableFuture allows non-blocking code execution. Two methods, join() and get(), are used to retrieve the result of an asynchronous computation. Join() throws an unchecked CompletionException, making it convenient for new code that doesn't require explicit exception handling. Get() throws checked exceptions such as InterruptedException and ExecutionException and supports timeouts, providing more detailed exception handling. While join() is generally preferred for simplicity in new code, get() maintains compatibility with legacy systems.
