Answer / sandeep
While exception handling if exception is thrown programme
will abort abnormally but it can leads to some problamatic
situation..hence we have to ensure some code will always run
whtever happen..finalization does so. Some useful tasks that
we have to do ( cleaning up some resources or closing some
connection or socket etc) we can gurantee it will be done by
simply putting it in finally block.
It will run always (Unless System.exit() is not called) and
hence future problem can be handled.

Finalization is a facility provided by Java for classes who
use native resources to clean up before the objects are
garbage collected.
Since native resources or allocations are beyond the control
of Java's garbage collector, the responsibility of cleaning
up that native allocations falls on the object's
finalization code which shud ideally initiate quick clean up
operations and free any native memory it has allocated.
If finalization is not done, then the native resources wud
be left in the memory even after thier related Java
instances have been removed by the Java's GC. Hence it is an
invaluable feature.
But it needs to be used with caution as finalization
consumes more processing by Java

Answer / srikanth reddy
The purpose of finalization is to give an unreachable
object the opportunity to perform any cleanup processing
before the object is garbage collected.
