Well, there's always the JDK's Javadoc documentation (for class
java.lang.Throwable) :-).
Throwable is the parent class of absolutely every kind of exception or
error
that can be thrown -- hence it's name. So, doing a catch for
"Throwable"
catches any and all exceptions, because they are all subclasses of
Throwable.
A common approach is to deal specifically with certain kinds of
exceptions based
on their type, and have a catch-all for everything else. As long as you
put the
catch-all block last:
try {
... do something ...
} catch (ServletException e) {
... handle a servlet exception ...
} catch (IOException e) {
... handle an input/output error ...
} catch (Throwable t) {
... handle anything else ...
}
