Java

public void escolhaDaTabela() {
int indiceLinha = tblDados.getSelectedRow();
txtCodMaterial.setText(tblDados.getValueAt(indiceLinha, 0).toString()); //String
txtTipo.setText(tblDados.getValueAt(indiceLinha, 1).toString()); //String
txtNomeMaterial.setText(tblDados.getValueAt(indiceLinha, 2).toString()); //String
txtNossoCusto.setText(tblDados.getValueAt(indiceLinha, 3).toString()); //Double
txtPrecoDeVenda.setText(tblDados.getValueAt(indiceLinha, 4).toString()); //Double
txtMedida.setText(tblDados.getValueAt(indiceLinha, 5).toString()); // Integer
*** Essa linha 5 ocorre um erro e não consigo resolver, o erro ocorre porque o campo do DB é Integer.
Como resolvo isso? Pls

Seu erro é um simples Null Pointer, ou seja, tem algum coisa nula na linha:

txtMedida.setText(tblDados.getValueAt(indiceLinha, 5).toString()); // Integer


Ou você coloca um debug para verificar o que está nulo, ou você refatora o código:

Integer i = tblDados.getValueAt(indiceLinha, 5);
String s = i.toString();
txtMedida.setText(s);


Tem certeza que o campo do banco não aceita valor nulo?

Boa tarde,

Consegue colocar o stacktrace do problema? O dado ser Integer não devia ser um problema.
