Hi, I would like to make a payment system, thanks to sql the problem is that I would like to do this with a list but sql does not support so I would like to do it with json but I do not know how it works
JSON or Javascript Object Notation, is an object (therefore is opened and closed with {}) that can contain every type of data: string, integer, float, array, object etc. that is used to store data easily, for ease, you can use it in java with the following libraries: Jackson, JSONSimple, Gson. @Foulehistory this is basically what JSON is. If you want to make a payment system I would recommend Tebex (Buycraft), it can also be used with an SQL database.
