Java Threads Interview Question:

Can Java object be locked down for exclusive use by a given thread?
Or
What happens when a thread cannot acquire a lock on an object?

Yes. You can lock an object by putting it in a "synchronized" block. The locked object is inaccessible to any thread other than the one that explicitly claimed it. If a thread attempts to execute a synchronized method or synchronized statement and is unable to acquire an object's lock, it enters the waiting state until the lock becomes available.
