Answer / amit2009mca

the catch and decalre rule to handle the exception
1)when we don't want to handle the particular exception
we declare it
means to say that imagine that you go to market class
and call the purchase method to purchase a book.
but the shopkeeper has n't the particular book so its
responsibility to shopkeeper that he inform you about
particular exception so he declare the exception
Booknotfound and throws like this
class Market
{
public void purchase throws booknotfound
{
}
}
so this is called the declare rule

another is
2)catch
imagine you call the purchase method to buy book but there
is some problem like book is tore up or book is in godown
so its peoblenm pf the sopkeeper so its responsibility of
shopkeeper to handle this particular exception
then the Catch rule comes in a ligtht
like theis
class Narket
{
public purchase()
{
try{
}
catch(Booktoreupexception e or BookinstoreException e)
{
}
thanks if you got this because these all are just for
checked exception thanks
