Every Java Object will have a lock or only the thread objects will have a lock?
Somebody please clear this.

All objects can be used as a lock.

The Threads Tutorial takes about this in detail in the Synchronization section.

That's not correct. A lock is acquired by using synchronization, which can be done in any class, not just threads.

Of course, all code runs inside of a thread, even single-threaded code, so in that sense locks are always associated to threads. But I don't think that was what you meant.
