if i put the following:
public static void main(String aasd) throws Exception
then,only Exception occurs
If a method declare that it throws a Exception, then the user/caller should take the responsible to handle that exceptions. So, your foo() method throws exception, so you need to handle it or declare it as re-throwing it in the calling method, in your case, the main() method

You don't need to handle the RuntimeExceptions!

You should try to format your code consistently (indents, use of curly braces, and so on), AND you should use JavaBeans naming standards for your classes, methods and variables. Otherwise the programmers who work with you might throw you out a window
