Eu construir um método sobrecarregado toString() para listar o modelo. Estou utilizando um campo de data de nascimento. Quando adiciono o campo no PostgreSQL utilizando o parseamento da Classe SimpleDateFormat funciona, mas quando tento fazer a leitura, não consigo. Segue o codigo abaixo e o erro:
@Override
public String toString() {
try {
String contatos = "\nNome: " + this.nome;
contatos += "\nEmail: " + this.email;
contatos += "\nEndereço: " + this.endereco;
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date data = (Date) sdf.parse(this.dataNascimento.toString());
Calendar calendar = Calendar.getInstance();
calendar.setTime(data);
contatos += "\nData de nascimento: " + calendar.toString();
return contatos;
} catch (Exception ex) {
ex.printStackTrace();
}
return null;
}
Classe de teste
import java.util.List;
import br.com.caelum.jdbc.dao.ContatoDao;
import br.com.caelum.jdbc.modelo.Contato;
public class TestaLista {
public static void main(String[] args) {
ContatoDao dao = new ContatoDao();
List<Contato> contatos = dao.getLista();
contatos.forEach((c) -> System.out.println(c.toString()));
}
}
O erro que o Java exibe para mim…

Preciso de um auxilio em relação a isso. Desde já agradeço!
