You define a bean: Drink with some attributes (Name and Price)

You define your main class where you do the converting actions.

👨‍💻 𝐒𝐧𝐢𝐩𝐩𝐞𝐭:

Jsonb jbCola = JsonbBuilder.create();
System.out.println("JSONB demo");
Drink cola = Drink.builder().name("Cola").price(4d).build();
System.out.println("Drink to proceed:" + cola.toString());
String jsonDrink = jbCola.toJson(cola);
System.out.println("To JSON: " + jsonDrink);
Drink dCola = jbCola.fromJson(jsonDrink, Drink.class); System.out.println("From JSON: " + dCola);
