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.
