Answer Posted / janet
final: final key word 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 it's initialize 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.
