In a single threaded system program executes in a sequence
line by line. Multithreaded system can allow multiple
threads to execute a program parallel in multiple instances.
If there is any part of code dealing with the object data
modification, there is no guarantee that it will not be
attempted any more than one thread at a time.
there's a need to make sure that such kind of code should be
executed exclusively. To achieve this in Java we a concept
of LOCK. Using Lock mechanism thread holds complete hold on
an object and object is also can not be access any other
thread except the thread holding that lock. Lock is an
object level control and one thread only can hold it at a time.
