Java ExecutorService.invokeAll() is a method in the Java ExecutorService interface that submits a collection of tasks for execution and waits for them to complete. It returns a list of Java Future objects that can be used to retrieve the results of each task. Introduced in Java 2004 with Java 5, invokeAll() is often used when a large number of tasks need to be executed concurrently, and the results from each task are needed once they are complete.
