JAVA MULTI-THREADING Design and implement a barrier using monitors. Your barrier should
support one method, namely arriveAndWait( ). A thread invoking the
method is blocked until all threads have arrived at the barrier (in
other words, invoked the arriveAndWait( ) method of the barrier)
at which point all threads are released from the barrier and can
resume their respective executions. The barrier should be reusable,
that is, threads can use the same barrier object multiple times to
synchronize with each other. Ensure that your design and
implementation of a barrier satisfies the following two properties:
(a) safety: no thread is released from the barrier prematurely,
and (b) liveness: once all threads have arrived at the barrier,
all threads are released from the barrier eventually.
