Arrayindexoutofboundsexception when trying to fill a Jtable from a query

Question

I am performing a query in the database to pass the information to a JTable. However, when performing a query, the following error appears:

Answer 1

Your code is not reproducible so you can’t be sure if it’s the only problem with it, but the column array only has one index and you seem to be trying to configure 30 columns. Obviously it won’t work, since you passed the variable colunas as a parameter of TableModel, And in this variable is a sequence of strings being concatenated which, I imagine, should be the columns. But by concatenating everything, you’ve made it a single string occupying only one index and not an array with 30 different.

You need to separate each value between double quotes and separate with comma, not concatenate with + how are you doing:

String[] colunas = new String[]{"FK_COD_IDD", "COD_CHAPA", "DSC_NOME",
    "DSC_CARGO", "DSC_SEXO", "DSC_IDADE", "COD_CPF", "COD_PIS", "DSC_TEL", 
    "DSC_END", "DSC_COMP", "COD_NUM", "DSC_BAIRRO", "DSC_CIDADE", "DSC_CEP", 
    "DSC_UF", "COD_CTPS", "COD_SERIECTPS", "DSC_SITE", "DSC_DATANSC", 
    "DSC_DATAAD", "DSC_HORARIO", "DSC_BP", "DSC_CAT", "DSC_GESTOR", 
    "DSC_DATADESL", "DSC_DATAPG", "DSC_DISP", "DSC_MOTIVO", "DSC_OBS", "DSC_HOMO"};
