293 project for converting a string into an integer.
@author Shaun Howard
To use, must supply a string number with the correct syntax to the Numbers.stringToInteger() method.
The program will parse the string into an integer if the syntax is correct, otherwise, an exception will be thrown by the code when the string fails.
Thus, the error handling component is covered by throwing an exception at the point in the code where the error is found during processing.
A class was added called NumbersError that checks for most bad input where NumbersSyntaxChecker lacked, which was mostly in everything.
The differentiation between these classes is determining if the number is in the proper number format (SyntaxChecker) vs whether the input given was bad input (Error). Things like doubles are checked in the Error class. Things like order of numbering and places are checked in the SyntaxChecker class.
New code is in "new" folder. Patch is in repo.
Defects found include incorrect processing of: One word numbers Two word numbers Hundred preceding thousand Million preceding thousand Negative numbers Adjacent values that were the same place (i.e. hundred hundred) Invalid order of string Double negatives Double zeroes Weird spaces (beginning, adjacent, end)
