## Uses of Class
java.util.concurrent.TimeUnit

Packages that use TimeUnit
java.util.concurrent | Utility classes commonly useful in concurrent programming.
java.util.concurrent.locks | Interfaces and classes providing a framework for locking and waiting for conditions that is distinct from built-in synchronization and monitors.
javax.swing | Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms.
