Java language realizes simple hotel front desk management small function of example code

The author is a new Macey who has just hit the road. I hope you can correct any problems!

The following are the topics:
Write a program for a hotel: hotel management system, simulate booking, check-out, print all room status and other functions.
1. The user of this system is: hotel front desk.
2. The hotel uses a 2-dimensional array to simulate. "Room [] [] rooms;"
3. Every room in the hotel should be an java object: Room
4. Every room Room should have: room number, room type and whether the room is free.
5. Functions that the system should provide externally:
You can book a room: the user enters the room number and makes a reservation.
Can check out: The user enters the room number and checks out.
You can view the status of all rooms: The user should be able to view the status of all rooms by entering a command.

The following is the source code of this function:
