Question about Java synchronized

Question

The Java documentation says that \"it is not possible for two invocations of synchronized methods on the same object to interleave\". What I need to know is whether synchro

Answer 1

Not unless the method is static. A synchronized non-static method takes a lock on the object (instance) on which it is invoked, not on the class.

A synchronized static method takes a lock on the class, so that could help - but it's often not very practical.

What you could do is have a static member object in your class, and do a synchronized block on that (class-global) object in your process method.
