How to Solve : Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: -1 - netbeans-8

Question

I tried to make a delete button in netbeans but after successfully deleting, a warning appears. is there any that can?
private void jButtonDeleteActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
int index = jTableSurat.getSelectedRow();
// jika tidak ada
if (index == -1) {
JOptionPane.showMessageDialog(null, "Pilih baris yang akan di-delete!");
return;// maka proses dibatalkan
}
suratmasukkeluardomain suratmasuk=SuratModel.findOne(index);
SuratService.delete(suratmasuk);
bersih();
SuratModel.delete(index);
}
Exception coming:
