a. Sunshine Seashore Supplies rents beach equipment to tourists. In previous chapters, you have developed a Rental class that holds equipment rental information. Now modify the Rental class as follows: Modify the method that sets the contract number in the Rental class so that if the argument passed to the method is not a four-character String that starts with a letter followed by three digits, then the contract number forced to A000. If the initial letter in the contract number is not uppercase, force it to be so. Add a contact phone number field to the Rental class. Add a set method for the contact phone number field in the Rental class. Whether the user enters all digits or any combination of digits, spaces, dashes, dots, or parentheses for a phone number, store it as all digits. (Assume a phone number is 10 digits and does not require a leading digit that might be needed when dialing.) For example, if the user enters (920) 872-9182, store the phone number as 9208729182. If the user enters a number with fewer or more than 10 digits, store the number as 0000000000. Add a get method for the phone number field. The get method returns the phone number as a String constructed as follows: parentheses surround a three-digit area code, followed by a space, followed by the three-digit phone exchange, followed by a hyphen, followed by the last four digits of the phone number. Save the file as Rentaljava. b. Create a RentalDemo application that does the following: Prompts the user for a contract number and number of minutes for three Rental objects. Prompts the user for and retrieves a contact phone number for each of the Rental objects. Displays the contract number and contact phone number for each Rental. Save the file as RentalDemo.java.
