public final class UtilValidate
extends java.lang.Object
```
General input/data validation methods Utility methods for validating data, especially input. See detailed description below.
SUMMARY

This is a set of meethods for validating input. Functions are provided to validate:
- U.S. and international phone/fax numbers
- U.S. ZIP codes(5 or 9 digit postal codes)
- U.S. Postal Codes(2 letter abbreviations for names of states)
- U.S. Social Security Numbers(abbreviated as SSNs)
- email addresses
- dates(entry of year, month, and day and validity of combined date)
- credit card numbers

Supporting utility functions validate that:
- characters are Letter, Digit, or LetterOrDigit
- strings are a Signed, Positive, Negative, Nonpositive, or Nonnegative integer
- strings are a Float or a SignedFloat
- strings are Alphabetic, Alphanumeric, or Whitespace
- strings contain an integer within a specified range

Other utility functions are provided to:
- remove from a string characters which are/are not in a "bag" of selected characters
- strip whitespace/leading whitespace from a string

==============================================================================
NOTE: This code was adapted from the Netscape JavaScript form validation code,
usually found in "FormChek.js". Credit card verification functions Originally
included as Starter Application 1.0.0 in LivePayment.
