如何在abstractTableModel中获取自己的方法？

Question

我正在使用我自己的TableModel构建一个Swing-Gui并在JScrollPane中有一个JTable对象。模型核是包含数据的LinkList。我这样做是因为LinkedList能够随时插入行作为Object []而无需替换2D数组。我写了一个方法，在我的LinkedList中插入一个Object []，但我不能通过调用main方法中的TableModel从JTable调用它，我不知道为什么。有人有想法吗？

public class TableModel extends AbstractTableModel {    

    String[] columnNames = { "Kundennummer","Firma","Nachname","Vorname","Telefonnummer","Emailadresse","Adresszeile 1","Adresszeile 2", "PLZ", "Ort", "Geburtsdatum"};

    int anzahlAttribute = 11;
    LinkedList<Object[]> data;

    public TableModel(LinkedList<Object[]> rows){
        this.data = rows;
    }

    @Override
    public String getColumnName(int col) {
        return columnNames[col].toString();
    }
    /**
     * @see javax.swing.table.TableModel#getColumnCount()
     */
    @Override
    public int getColumnCount() {
        // TODO Auto-generated method stub
        return columnNames.length;
    }

    /**
     * @see javax.swing.table.TableModel#getRowCount()
     */
    @Override
    public int getRowCount() {
        // TODO Auto-generated method stub
        return data.size();
    }

    /**
     * @see javax.swing.table.TableModel#getValueAt(int, int)
     */
    @Override
    public Object getValueAt(int arg0, int arg1) {
        // TODO Auto-generated method stub
        try{
        return data.get(arg0)[arg1];
        }catch(ArrayIndexOutOfBoundsException e){
            return "";
        }
    }

     public Class getColumnClass(int c) {
            return getValueAt(0, c).getClass();
     }

     @Override
     public void setValueAt( Object val, int row, int column ){
       data.get(row)[column] = val;
       this.fireTableDataChanged();
     }

     public void insertRow(Object[] rowData){
         this.data.add(rowData);
         this.fireTableRowsInserted(data.size()-1, data.size()-1);
     }





public class PaneCenter extends JScrollPane implements Panelsetter {

    private static PaneCenter c;
    private static JTable kundenTabelle;
    private TableModel tm;

    private PaneCenter(){
        super();
    }

    /**@  Constructor
     * 
     *
     *
     *
     *@param arg0
     */
    public PaneCenter(Component arg0) {
        super(arg0);
        // TODO Auto-generated constructor stub
    }

    public static PaneCenter getInstance(){
        if(c == null){
            c = new PaneCenter(kundenTabelle = new JTable());
        }
        return c;
    }

    public void setPanel(LinkedList<Object[]> data){
        c.setBackground(Color.GRAY);
        c.setBorder(new LineBorder(Color.black));
        c.setPreferredSize(new Dimension(500,350));
        c.setMinimumSize(new Dimension(500,350));
        c.setMaximumSize(new Dimension(500,350));
        kundenTabelle.setModel(tm = new TableModel(data));
        kundenTabelle.setAutoResizeMode(0);
        kundenTabelle.setSelectionMode(0);
    }

    public JTable getKundenTabelle() {
        return kundenTabelle;
    }

    public TableModel getTableModel(){
        return tm;
    }

    /**
     * @see interfaces.Panelsetter#setPanel()
     */
    @Override
    public void setPanel() {
        // TODO Auto-generated method stub

    }





public class Run {

    public static void main(String[] args) {
        // TODO Auto-generated method stub

        Object[] aa = {"1", "2", "3", "4", "5", "1", "2", "3", "4", "5", "11"}
        PaneCenter.getInstance().setPanel(Bank.getCustomerDataArray())
        PaneCenter.getInstance().getKundenTabelle().getModel().insertRow(aa);


        Frame.getInstance().addPanels(PaneCenter.getInstance());
        Frame.getInstance().setVisible(true);

    }
