Hi all,

I tried the following code:



There was a compile time error 'Unreachable catch block for FileNotFoundException. The exception is never thrown from the try block'
Same for IOException.

But when I tried to catch Exception, no compile time error was displayed! Why is that so?

You need something that throws that FileNotFoundException:



http://java.sun.com/docs/books/jls/third_edition/html/exceptions.html 11.2.3 Exception Checking "unless E1 is the class Exception."

Pats,

I'd say...read up on checked/unchecked exceptions and try to understand their implications. Also, read this
JLS-section 14.21 to understand the circumstances in which a catch becomes un-reachable.
