public enum TimeUnit2 extends Enum<TimeUnit2>
A TimeUnit is mainly used to inform time-based methods
how a given timing parameter should be interpreted. For example,
the following code will timeout in 50 milliseconds if the lock
is not available:
Lock lock = ...; if ( lock.tryLock(50L, TimeUnit.MILLISECONDS) ) ...while this code will timeout in 50 seconds:
Lock lock = ...; if ( lock.tryLock(50L, TimeUnit.SECONDS) ) ...Note however, that there is no guarantee that a particular timeout implementation will be able to notice the passage of time at the same granularity as the given TimeUnit.

public void timedWait(Object obj, long timeout) throws InterruptedException
For example, you could implement a blocking poll
method (see BlockingQueue.poll
)
using:
public synchronized Object poll(long timeout, TimeUnit unit) throws InterruptedException { while (empty) { unit.timedWait(this, timeout); ... } }
obj
- the object to wait ontimeout
- the maximum time to wait. If less than
or equal to zero, do not wait at all.InterruptedException
- if interrupted while waiting.Object.wait(long, int)
public void timedJoin(Thread thread, long timeout) throws InterruptedException
thread
- the thread to wait fortimeout
- the maximum time to wait. If less than
or equal to zero, do not wait at all.InterruptedException
- if interrupted while waiting.Thread.join(long, int)
public void sleep(long timeout) throws InterruptedException
timeout
- the minimum time to sleep. If less than
or equal to zero, do not sleep at all.InterruptedException
- if interrupted while sleeping.Thread.sleep(long)
