The Condition interface has other versions of the await() method, which are as follows:

• await(long time, TimeUnit unit): Here, the thread will sleep until:
  • It's interrupted
  • Another thread calls the signal() or signalAll() methods in the condition
  • The specified time passes
  • The TimeUnit class is an enumeration with the following constants: DAYS, HOURS, MICROSECONDS, MILLISECONDS, MINUTES, NANOSECONDS, and SECONDS

• awaitUninterruptibly(): The thread will sleep until another thread calls the signal() or signalAll() methods, which can't be interrupted
• awaitUntil(Date date): The thread will sleep until:
  • It's interrupted
  • Another thread calls the signal() or signalAll() methods in the condition
  • The specified date arrives

You can use conditions with the ReadLock and WriteLock locks of a read/write lock.
