I have a question regarding the synchronization of method..
can a thread access the non-synchronized method of an instance of class when the other thread have the lock on the same instance of class?
because as i know the lock is for object , so if a class contains both synchronized and non synchronized methods , and if one thread has a lock on object(instance) , is that possible for other thread to call the non synchronized method using the same instance?

The problem, if any, is keeping the data in in instance in a consistent state while two or more threads are active in the instance. I just went through a very convoluted discussion in which I figured all this Thread stuff out. Look at it this way:
It may seem odd, but on a multiple processor machine, the two threads can actually be at the same point at the same time. If that is the case, a variable on the left of the assignment operator can be changed by Thread_1 before Thread_2 can read it. Sounds incorrect, but on a Hydra with a theoretical peak performance of 4.8 Teraflops, total memory of 1.2 Terabytes, and a 21 Terabyte DDN disk array, keeping up with Who's on First can resemble Titanic in 30 seconds, re-enacted by bunnies.
