In-Depth Information
In this program, divide-by-zero errors are handled locally, by
genException( )
, but an
array boundary error is rethrown. In this case, it is caught by
main( )
.
A Closer Look at Throwable
Up to this point, we have been catching exceptions, but we haven't been doing anything
with the exception object itself. As the preceding examples all show, a
catch
clause speci-
fies an exception type and a parameter. The parameter receives the exception object. Since
all exceptions are subclasses of
Throwable
, all exceptions support the methods defined by
Throwable
. Several commonly used ones are shown in
Table 9-1
.
