Synchronized methods and blocks are implemented in the applet class by acquiring a lock before running
|
|
Code will therefore not run at the same time as other code that needs access to the same resource.
|
|
Each object has one lock associated with it and each class has exactly one lock
|
|
When invoked, a synchronized method waits until it can acquire the lock for the current instance (i.e., this); a static synchronized method waits to acquire the class lock
|
|
Lock is released when code is done executing
|
|
Locks are advisory
|
|
synchronized blocks specify the object on which to synchronize
