Simply put, the Future class represents a future result of an asynchronous computation . This result will eventually appear in the Future after the processing is complete. Let’s see how to write methods that create and return a Future instance.22 Ara 2021
Read moreWhat is Future multithreading?
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.

Future , represents the result of an asynchronous computation . When the asynchronous task is created, a Java Future object is returned. This Future object functions as a handle to the result of the asynchronous task.24 Eki 2018
Read moreHow is Future implemented in Java?
Future was introduced in Java 5. The value is retrieved from a future with get , which blocks until the value is ready. FutureTask class is an implementation of Future that implements Runnable , and so may be executed by an Executor .12 Kas 2021

Read moreWhy do we use Future in Java?
The Future class in Java is another way to write asynchronous code . By using Future and FutureTask, you can write a method that does long computation but returns immediately. Those methods, instead of returning a result, return a Future object. You can later get the result by calling the Future.
