Exception handling is not a must of programming. But it is
a cleaner way of getting signal if something goes wrong in
the code. Prior to exceptions people used return values of
functions for reporting errors to application using the
classes inside libraries. The application would call some
function(defined inside class) from within try bock. Now if
something goes wrong then the function(defined inside the
class) would throw an exception. This exception is then
handled by catch block in the application.
