Causes the current thread to wait until another thread invokes the
java.lang.Object.notify()
method or the
java.lang.Object.notifyAll()
method for this object.
In other words, this method behaves exactly as if it simply
performs the call wait(0)
.
The current thread must own this object's monitor. The thread
releases ownership of this monitor and waits until another thread
notifies threads waiting on this object's monitor to wake up
either through a call to the notify
method or the
notifyAll
method. The thread then waits until it can
re-obtain ownership of the monitor and resumes execution.
As in the one argument version, interrupts and spurious wakeups are possible, and this method should always be used in a loop:
synchronized (obj) { while (<condition does not hold>) obj.wait(); ... // Perform action appropriate to condition }This method should only be called by a thread that is the owner of this object's monitor. See the
notify
method for a
description of the ways in which a thread can become the owner of
a monitor.
IllegalMonitorStateException | if the current thread is not the owner of the object's monitor. | |
InterruptedException | if any thread interrupted the current thread before or while the current thread was waiting for a notification. The interrupted status of the current thread is cleared when this exception is thrown. |
