テーブルモデルから選択した行を取得するには? 私は次のことを試しました....

checkBoxes[t].addActionListener(new ActionListener() {
  public void actionPerformed(ActionEvent  e) {

    int index = -1;
    for (int i = 0; i < checkBoxes.length; i++) {
      if (checkBoxes[i] == e.getSource()) {

        String Status=null ;
        DbUtility ViewAbsenties=new DbUtility();
        ViewAbsenties.loadDriver();
        ViewAbsenties.connect();

        TableModel tm;
        tm = table3.getModel();

        if (checkBoxes[i].isSelected() == true) {
          Status  =(String) tm.getValueAt(i,8);
          System.out.println("Status : " + Status );

        }
      }
    }
  }
}

上記のコードを実行すると、次のエラーが発生します。
