this rule is actually for handling the exceptions:

that is there are two ways by ehich u can handle the exception :

1:either you use the try catch statement and enclose the appropriate code in the try catch block,this is called as the catch or the HANDLE rule

2:you can also use the throw and throws statement instead of using the try catch block i.e you should specify the exceptions that your method is capable of throwing(only checked)

eg void MyMethod() throws IOEception,any other exception just separate them with commas................
{
/*your code and throw statement at appropriate step that throws the exception
and don't use the try catch statement in this case
EG throw new MyException(arguments if any);
this instantiates MyException class*/
}
this is called as DECLARE RULE
