Olá Pessoal,
Esse é meu primeiro post.
Tenho que fazer um trabalho pra faculdade, de um SISTEMA DE LIVRARIA em MVC.
Só que, não posso usar BANCO DE DADOS.
Minha dúvida é em relação a exibição “do que eu cadastrei”
Como faço pra exibir o que cadastrei, e, se eu quiser fazer um campo CONSULTA, como ficaria?
Usando esse exemplo:
Modelo;
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package modelo;
/**
*
* @author alunolab07
*/
public class Autor {
private String nome;
private int idade;
public int getIdade() {
return idade;
}
public void setIdade(int idade) {
this.idade = idade;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
}/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package modelo;
import java.util.ArrayList;
/**
*
* @author alunolab07
*/
public class Persistencia {
public static ArrayList<Autor> vetAutor = new ArrayList<Autor>();
public static boolean cadastrarAutor(Autor a){
vetAutor.add(a);
return true;
}
public static ArrayList<Autor> retornaTodoVetorAutor(){
return vetAutor;
}
}Controle;
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package controle;
import modelo.Autor;
import visao.InterfaceGrafica;
/**
*
* @author alunolab07
*/
public class Aplicacao {
public boolean controleCadastrarAutor(InterfaceGrafica i){
Autor a = new Autor();
a.setIdade(Integer.parseInt( (i.getjTextField2()).getText()) );
a.setNome( (i.getjTextField1()).getText() );
a.modeloCadastrarAutor(a);
return true;
}
}Visão;
/*

* and open the template in the editor.
*/
/*

*
