1 void notify()
2 void notifyAll()
  • These methods must be called from a synchronized method.
  • These methods notify a waiting thread or threads.
3 notify() notifies the thread associated with the given synchronization object that has been waiting the longest time
4 notifyAll() notifies all threads associated with the given object and is therefore safer than notify()
5 One can mark a variable as "threadsafe" to inform the compiler that only one thread will be modifying this variable.
