Boa tarde. Eu estou fazendo um sistema CRUD para fazer cadastro de pessoas dentro de um clube utilizando JFrame + PostgreSQL. Só gostaria saber que alternativas eu poderia ter de mostrar uma mensagem para confirmação de exclusão ou cadastro de uma nova pessoa. Não sei se o jeito certo é criar um novo JFrame para isto, JOptionPane ou algo do tipo. O código está logo abaixo:

Connection conecta; PreparedStatement pst; ResultSet rs; public frmCadUsuarios() throws ClassNotFoundException { initComponents(); this.setLocation(330, 100); conecta = ConectaBD.conectabd(); //Conectar com o banco de dados listarDesbravadores(); //Inicializar lista } public void listarDesbravadores() { String sql = "Select * from usuarios order by codigo Asc"; try { pst = conecta.prepareStatement(sql); rs = pst.executeQuery(); tblDesbravadores.setModel(DbUtils.resultSetToTableModel(rs)); } catch(SQLException error) { JOptionPane.showMessageDialog(null, error); } } public void cadastrarDesbravadores() { String sql = "Insert into usuarios(nome, telefone, endereco) values (?,?,?)"; //? > Inserção dinâmica, sem saber o valor try { pst = conecta.prepareStatement(sql); pst.setString(1, txtNome.getText()); pst.setString(2, txtTelefone.getText()); pst.setString(3, txtEndereco.getText()); pst.execute();//Manda executar //Mensagem de informação JOptionPane.showMessageDialog(null, "Desbravador cadastrado com sucesso!!!", "Confirmação", JOptionPane.INFORMATION_MESSAGE); listarDesbravadores(); //Atualiza a janela com as informações dentro dela } catch(SQLException error) { JOptionPane.showMessageDialog(null, error); } } public void pesquisarDesbravadores() { String sql = "Select * from usuarios where nome like ?"; try { pst = conecta.prepareStatement(sql); pst.setString(1, txtPesquisar.getText()+"%"); //Quando apagar, trazer as informações, usado com o like rs = pst.executeQuery(); tblDesbravadores.setModel(DbUtils.resultSetToTableModel(rs)); } catch(SQLException error) { JOptionPane.showMessageDialog(null, error); } } public void mostrarItens() { int seleciona = tblDesbravadores.getSelectedRow();//Buscar valor que estiver selecionado txtCodigo.setText(tblDesbravadores.getModel().getValueAt(seleciona, 0).toString());
