This Exercise contains two classes: ValidateTest and Validate. The Validate class uses try-catch and Regex expressions in methods to test data passed to it from the ValidateTest program. Please watch the related videos listed in Canvas and finish creating the 3 remaining methods in the class. The regular expression you will need for a Phone number is: "^\\(?(\\d{3})\\)?[- ]?(\\d{3})[- ]?(\\d{4})$" and for an SSN: "^\\d{3}[- ]?\\d{2}[- ]?\\d{4}$" This exercise is meant to be done with the video listed in the Assignment page for Week 10.
