Editor to share with you how to use Java to achieve a simple ordering system, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

Program control analysis:

1. Welcome page loop: do-while

2. Scanner control input

3. Select a page loop: switch-case

Request:

Order information: String 2D array

Serial number, name, meal name, number, price, total price, address, time (10-20), status (booked, completed), heat (int)

Sign the order: change the status of the order, you can sign for it if it has been booked, and you can't sign for it again if it has been completed.

Delete order: the outstanding order cannot be deleted and the serial number should be changed accordingly.

I want to like: like the corresponding food and show it.
