The method will throw an exception by ensuring the value of b before the result "long" is calculated avoiding unexpected results.

This feature adds illegalArgumentException handling for divisors of 0. This exception is thrown for each method regardless of how the division is obtained. The method of using Exceptions is useful as future development allows for change in the exception handling, futureproofing the code to change how we want to handle division by 0 errors.
