Thanks for the reply. Is there any advantage apart from the rule that needs to be followed?

class MyException{ public static void main(String ar[]) { int x=0; try { System.out.println(100/x); } catch(Exception e) { } catch(ArithmeticException ae) { System.out.println("u r inside arithmetic exception"); } } } In general,Exception is the super class of all exceptions,so,we hv to give general exception first then smaller exceptions(in case,if u mention normal and smaller exceptions).....or we can directly mention smaller exceptions with out giving normal exception....or we can directly give normal exception only(without giving smaller exceptions),which can handles all exceptions under it.
