setKeepAliveTime
Sets the thread keep-alive time, which is the amount of time that threads may remain idle before being terminated. Threads that wait this amount of time without processing a task will be terminated if there are more than the core number of threads currently in the pool, or if this pool .allowsCoreThreadTimeOut. This overrides any value set in the constructor.
Parameters
time
the time to wait. A time value of zero will cause excess threads to terminate immediately after executing tasks.
unit
the time unit of the time argument
