Question

When a new user logs in for the first time on a website, the user has to submit personal information, such as user_id, password, name, email address, telephone number, and so forth. Typically, there arc two fields for passwords, requiring the user to enter the password twice, to ensure that the user did not make a typo in the first password field. Write a class encapsulating the concept of processing a form with the following elements: User_id Password Reenter password Email address Name Street address City State Zip Telephone In your class, write the following methods: A constructor with one parameter, a sequence of 10 words in an array of Strings, your only instance variable. Accessor, mutator, toString, and equals methods. A method checking that no Strings in the array arc empty. (All fields are mandatory.) If at least one is empty, it returns false, otherwise, it returns true. A method returning the number of characters in the user_id. A method checking if the two Strings representing the passwords (representing the password typed in twice) are identical; if they are, it returns true', if not, it returns false. A method checking if the String representing the email address actually "looks like" an email address; to simplify, we can assume that an email address contains one and only one @ character and contains one or more periods after the @ character. If it does "look like" an email address, then the method returns true; otherwise, it returns false. A method checking if the String representing the state has exactly two characters. If it does, it returns true; otherwise, it returns false. Write a client class to test all the methods in your class.
