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

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 Javas garbage collector, the responsibility of cleaning
up that native allocations falls on the objects
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 Javas GC. Hence it is an
invaluable feature.

But it needs to be used with caution as finalization
consumes more processing by Java
