“Java проверила исключение” Ответ

Java проверила исключение

Java has a feature called "checked exceptions". 
That means that there are certain kinds of exceptions, 
namely those that subclass Exception but not RuntimeException, 
such that if a method may throw them, it must list them 
in its throws declaration, say: void readData() throws IOException. 
  IOException is one of those.

Thus, when you are calling a method that lists IOException 
in its throws declaration, you must either list it in your 
own throws declaration or catch it.

The rationale for the presence of 
checked exceptions is that for some kinds of exceptions,
you must not ignore the fact that they may happen, 
because their happening is quite a regular situation, 
not a program error. So, the compiler helps you 
not to forget about the possibility of such an 
exception being raised and requires you to handle it in some way.

Что вы делаете с проверенным исключением

I would either handle or declare. I Declare using THROWS keyword or handle by
using TRY&CATCH block. If I will use it again I would handle it. If it will
occur only once than I would use THROWS keyword
