Using the above code, call the constructor to create a new instance of the Student object named joe. The constructor method will take the four string values (first name, last name, address, username) and set the initial state of the Student object to be: firstname = "Joe", lastname = "Jones", address = "123 Oak St.", username = "JJones".
