Demo Examples

Divide By Zero

CWE-369

The following Java example contains a function to compute an average but does not validate that the input value used as the denominator is not zero. This will create an exception for attempting to divide by zero. If this error is not handled by Java exception handling, unexpected results can occur.


               
}
return totalTime / numRequests;

By validating the input value used as the denominator the following code will ensure that a divide by zero error will not cause unexpected results. The following Java code example will validate the input value, output an error message, and throw an exception.


               
}
return totalTime / numRequests;
throw ArithmeticException;
