RunPattern
creates a
ConcreteQueue
, then uses it to retrieve a sample
Contact
and two
Addresses
. The worker
thread in the queue processes these requests as they are added to the queue. The
ConcreteQueue
and its
associated worker thread can be used throughout the lifetime of a client application, performing any background
task required by the client as
RunnableTask
objects are added to its queue.
