When the asynchronous task is created, a Java Future object is returned.

You can use the Dataset/DataFrame API in Scala, Java, Python or R to express state in aggregation queries (as of Spark 2.1.1, subject to change in the future).

Thus, a Future is basically one way the main thread can keep track of the progress and result from other threads. java.lang.Void is a reference type for void (a placeholder that doesn't get instantiated). So you can look at Future the same way you look at Future, just keeping in mind what you know about void not returning any value. You can read more about these types here: The Future of Java Technologies. While it’s hard to predict the next big innovation in Java development and how that will impact the direction of Java as a language, you can certainly trace the impact that big changes in the Java enhancement process have had on dependent technologies. Reactive Java Technology Changes. Not all changes to Java technologies are innovative in nature.

Think of a Future as an object that holds the result – it may not hold it right now, but it will do so in the future (once the Callable returns). Thus, a Future is basically one way the main thread can keep track of the progress and result from other threads. java.lang.Void is a reference type for void (a placeholder that doesn't get instantiated). So you can look at Future the same way you look at Future, just keeping in mind what you know about void not returning any value.
