From json-b.net:

JSON-B is a standard binding layer for converting Java objects to/from JSON messages. It defines a default mapping algorithm for converting existing Java classes to JSON, while enabling developers to customize the mapping process through the use of Java annotations.

To serialize/deserialize a Java Object to/from JSON

The Java Class

public class Dog {
    public String name;
    public int age;
    public boolean bitable;
}

JSON-B API calls

public static void main(String[] args) {

    // Create a dog instance
    Dog dog = new Main.Dog();
    dog.name = "Falco";
    dog.age = 4;
    dog.bitable = false;

    // Create Jsonb and serialize
    Jsonb jsonb = JsonbBuilder.create();
    String result = jsonb.toJson(dog);

    System.out.println(result);

    // Deserialize back
    dog = jsonb.fromJson("{\"name\":\"Falco\",\"age\":4,\"bitable\":false}", Dog.class);

}

The JSON representation

{
    "name": "Falco",
    "age": 3,
    "bitable": false
}
