private String nome;
private String email;
public String getNome() {
return nome;
}
public String getEmail() {
return email;
}
public Usuario(String nome, String email) {
this.nome = nome;
this.email = email;
}
}
package br.com.ffm.info.waccesspapers.backbeans;
import java.util.ArrayList;
import java.util.List;
public class TesteManaged {
public List<Usuario> getUsuarios() {
ArrayList<Usuario> us = new ArrayList<Usuario>();
us.add(new Usuario("rodrigo", "noEmail"));
us.add(new Usuario("Urubatan", "noEmailTambem"));
