Enclosing Code in a try Block
The program begins by prompting the user to enter two integers. The integers are input in the condition of the
while loop (line 28). Line 34 passes the values to function
quotient (lines 10–18), which either divides the integers and returns a result, or throws an exception (i.e., indicates that an error occurred) on an attempt to divide by zero. Exception handling is geared to situations in which the function that detects an error is unable to handle it.
As you learned in Section 7.10,
try blocks enable exception handling, enclosing statements that might cause exceptions and statements that should be skipped if an exception occurs. The
try block in lines 32–36 encloses the invocation of function
quotient and the ...
