Foil 13 Threads and Synchronization II

From Java Tutorial 98- 4: Multi-Treading, Useful Java Classes, I/O and Networking NAVO Tutorial -- Sept 23 1998. by Geoffrey C. Fox, Nancy McCracken
void notify()
void notifyAll()
  • These methods must be called from a synchronized method.
  • These methods notify a waiting thread or threads.
notify() notifies the thread associated with the given synchronization object that has been waiting the longest time
notifyAll() notifies all threads associated with the given object and is therefore safer than notify()
One can mark a variable as "threadsafe" to inform the compiler that only one thread will be modifying this variable.
