Answer / aravinda reddy
1) Checked Exceptions extends Exception and
UncheckedExceptions extends RuntimeException.
2) Checked Exception must be caught in the code using try -
catch-finally or declared thrown where as unchecked
exceptions no need to catch or thrown declared
3) None is functionally better than the other
4) Checked Exception is most common excpetions while
coding, so may be authors have made it as mandatory to
handle the excpetion while coding
5) We can create custom checked and unchecked exceptions by
extending Exception and RuntimeException.

Answer / santosh mundhe
Unchecked Exception(Runtime Exception):
there is no need to declare runtime exceptions, in simple
words we can say that at run time JVM will handle the
exception.
Checked Exception(Compiletime Exception):
at compile time JVM will check for exception for that it's
compulsory to handle the exception.Checked exceptions force
you to catch the exception and to do something about it.
