Uses of Interface
java.util.concurrent.Future

Packages that use Future

Package	Description
java.nio.channels	Defines channels, which represent connections to entities that are capable of performing I/O operations, such as files and sockets; defines selectors, for multiplexed, non-blocking I/O operations.
java.util.concurrent	Utility classes commonly useful in concurrent programming.
javax.swing	Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms.
javax.xml.ws	This package contains the core JAX-WS APIs.
