Answer Posted / zama
final keyword are assigned to 3 different things such as
(1)___to variables:
if the variable is declared as final then value to
that variable can be assigned only once.
(2)___to methods:
if the method is declared as final then method cannot
be overridden.
(3)___to class:
if class is declared as final then class cannot be
inherited.
if finally block is defined in the main() then the stmt
under it will be executed surely,but if the stmt
System.exit(0); is before finally block then it is not executed.
finalize():
finalize() method is called by the Garbage
Collector on an object when there is no more reference to
the object.
finalize() is never run more than once on any object.
