SocSecException" For the "SocSecProcessor"class, the "isValid" method will need to use various string/wrapper class methods like: - length() - charAt(#) - Character.isDigit(char) Check for valid SSN format: ###-##-#### This program will ask the user for a persons name and social security number. The program will then check to see if the social security number is valid. An exception will be thrown if an invalid SSN is entered. You will be creating your own exception class in this program. You will also create a driver program that will use the exception class. Within the driver program, you will include a static method that throws the exception. ================================================================================================= 1. Create an exception class called SocSecException. The UML for this class is below. The constructor will call the superclass constructor. It will set the message associated with the exception to Invalid social security number concatenated with the error string. +SocSecException(String error) 2. Create a driver program called SocSecProcessor.java. This program will have a main method and a static method called isValid that will check if the social security number is valid. +main(args:String[ ]):void +isValid(ssn:String):boolean 1. In the main method: a) The main method should read a name and social security number from the user as Strings. b) The main method should contain a try-catch statement. This statement tries to check if the social security number is valid by using the method isValid. If the social security number is valid, it prints the name and social security number. If a SocSecException is thrown, it should catch it and print out the name, social security number entered, and an associated error message indicating why the social security number is invalid. c) A loop should be used to allow the user to continue until the user indicates that they do not want to continue. 2. The static isValid method: a) This method throws a SocSecException. b) True is returned if the social security number is valid, false otherwise. c) The method checks for the following errors and throws a SocSecException with the appropriate message. i) Number of characters not equal to 11. (Just check the length of the string) ii) Dashes in the wrong spots. iii) Any non-digits in the SSN. iv) Hint: Use a loop to step through each character of the string, checking for a digit or hyphen in the appropriate spots. 3. Compile, debug, and run your program. Sample output is shown below with user input in bold. Name? Sam Sly SSN? 333-00-999 Invalid the social security number, wrong number of characters Continue? y Name? George Washington SSN? 123-45-6789 George Washington 123-45-6789 is valid Continue? y Name? Dudley Doright SSN? 222-00-999o Invalid the social security number, contains a character that is not a digit Continue? y Name? Jane Doe SSN? 333-333-333 Invalid the social security number, dashes at wrong positions Continue? n =========================== After you finish the first problem, copy the driver to another driver file called SocSecFileIO.java. You will add the code that writes the name and correct ssn data to the file name given in the beginning. You will only write the data if the ssn is correct. Task #4 Writing Code to Handle Data Input Write a short driver program that reads the file you wrote in task #3 and displays it as (no data modification): Name ssn Sue Lee 458-789-7854 Kim Lee 784-897-5555
