Hi to all.
l am reading K&B book.There are something in "Thread Interaction" part which l could not understand.

in same part (Thread Interaction) l have read some sentences confused my mind.

For instance below sentence;

- The Object class has three methods, wait(), notify(), and notifyAll() that help threads
communicate about the status of an event that the threads care about.


in the above sentence specially l didnt understand
what K&B book wants to express by saying "status of an event that the threads care about"

What does K&B book want to express by saying "status of an event".
In that sentence what is event.

I believe the status of event means :
1. the event that one thread wait for a resources.
2. the event that one thread notifies the other thread that is waiting for the resource.
3. the even that one thread notifies all other threads that are waiting for the resource.
