Answer Posted / santhosi
final : final keyword can be used for class, method and
variables.
A final class cannot be subclassed and it prevents other
programmers from subclassing a secure class to invoke
insecure methods.
A final method can' t be overridden
A final variable can't change from its initialized value.
finalize( ) : finalize( ) method is used just before an
object is destroyed and can be called just prior to
garbage collection.
finally : finally, a key word used in exception handling,
creates a block of code that will be executed after a
try/catch block has completed and before the code following
the try/catch block. The finally block will execute whether
or not an exception is thrown.
For example, if a method opens a file upon exit, then you
will not want the code that closes the file
to be bypassed by the exception-handling mechanism. This
finally keyword is designed to address this
contingency.
