java - How to serialize Object to JSON?

Question

I need to serialize some objects to a JSON and send to a WebService. How can I do it using the org.json library? Or I'll have to use another one? Here is the class I need to serialize:

public class PontosUsuario {

    public int idUsuario;
    public String nomeUsuario;
    public String CPF;
    public String email;
    public String sigla;
    public String senha;
    public String instituicao;

    public ArrayList<Ponto> listaDePontos;


    public PontosUsuario()
    {
        //criando a lista
        listaDePontos = new ArrayList<Ponto>();
    }

}

I only put the variables and the constructor of the class but it also have the getters and setters. So if anyone can help please

Answer 1

Easy way to do it without annotations is to use Gson library

Simple as that:

Gson gson = new Gson();
String json = gson.toJson(listaDePontos);
