        Mobile[] mobileArray = Mobile.values();
        
        for (Mobile mobile : mobileArray)
        {
            System.out.println(mobile + " costs " + mobile.getPrice()
                    + " dollars");
        }
        System.out.println("-------------------");
        
        Mobile mobile = Mobile.Motorola;
        /*
         * Returns the name of this enum constant, exactly
         * as declared in its enum declaration.
         */
        
        String mobileName = mobile.name();
