In-Depth Information
The following program, named CatchDBZ, intercepts the Java
ArtihmeticException error response in the case of a division by zero.
Note that because ArithmeticException is unchecked it does not have to
be advertised in the header of the main() method.

{
int dividend = 100;
int divisor, result;
while(true)

The CatchDBZ.java program, listed previously, allows the user to enter
the divisor of an integer division operation. A special value of 100 is used
