*Do not copy anything from the internet

The following figure shows a train seat-numbering plan. Seat-numbering plan shows how the seats are laid out. In each row we have 4 seats. In total, we have 23 rows. Note: first and last row has 2 seats only. Step1: Create a Seat class that has: - Private int seatNumber with getter and setter methods. - Private String for passenger name with getter and setter methods. Note: if name is null this means seat is empty. - A constructor that takes seat number. - A method isEmpty that returns if the seat is empty or not. - A toString method that returns a string represents seat object's information. - A static method isValid that takes a seat number and returns if the seat number is valid or not. - A static method getRow that takes a seat number and returns the train row number if the seat number is valid. - A static method getColumn that takes a seat number and returns the train column number if the seat number is valid. Step 2: Draw the UML diagram for the Seat class Step 3: Create a Train class that has the following: - A private static ragged array of seats reflecting the mentioned train seat plan. - A method to reserve a seat. This method takes seat number and passenger's name. If the seat is empty, the seat will be reserved for the passenger and returns true. If not, it will returns false. - A method to delete a reserved seat. If the seat is not empty, the seat will be deleted and returns true. Else, it will returns false. - A method to delete all reserved seats.
