exceptions no need to catch or thrown declared

4) Checked Exception is most common excpetions while
coding, so may be authors have made it as mandatory to
handle the excpetion while coding

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.
