Ich benutze die sakila-Datenbank von MySQL, um meinen Code zu testen. Ich habe eine JTable, die ich verwende, um die Ergebnisse aus den Ansichten anzuzeigen. Einige funktionieren und andere werfen diesen Fehler:JTable throws Ausnahme im Thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException bei einigen Abfragen
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 16 >= 16

Der Code, den ich um das Modell zu bauen bin mit ist:
private void insertViewData(DataSet dataSet) {
//testUpdateJTable2();
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
Object[] headers = null;
Object[][] data = null;
try {
List<String> tmp = dataSet.getColumnNames();
headers = (String[]) tmp.toArray(new String[tmp.size()]);
data = dataSet.toArray();
DefaultTableModel model = new DefaultTableModel(data, headers) {
@Override
public boolean isCellEditable(int row, int column) {
return false; //To change body of generated methods, choose Tools | Templates.
}
};
tblData.setModel(model);
} catch (Exception e) {
String messageString = e.getMessage();
}
tblData.invalidate();
tblData.revalidate();
tblData.repaint();
}
});
}
Ein Beispiel für die Daten von einem der Abfragen zurückgegeben, die den Fehler hat, ist :
"Woodridge,Australia", "Jon Stephens", 33726.77
"Lethbridge,Canada", "Mike Hillyer", 33679.7
