? JTable getColumnName

[Geoff Jefferson]

I can't figure out why the column names are not showing up on my table.
Here is the code.

package mytablemain;

import javax.swing.table.AbstractTableModel;
import java.util.List;
import java.util.ArrayList;

class MyTableModel extends AbstractTableModel  {
    

  String[] columnNames = {"Testing", "This", "Table",
                                     "Model", "Today", "Six"};

  protected final List<ItemFile> dataList = new ArrayList<ItemFile>();
    
  public int getRowCount() {
    return dataList.size();
  }
  public int getColumnCount() {
    return columnNames.length;
    
  }
  @Override public String getColumnName(int col) {
    return columnNames[col];
  }
  @Override public Object getValueAt(int row, int col) {

  ItemFile item = (ItemFile)dataList.get(row);
           
      switch(col) {
         case 0: return item.one;
         case 1: return item.two;
         case 2: return item.three;
         case 3: return item.four;
         case 4: return item.five;
         case 5: return item.six;
         default: assert false; return null;
      }
  }
  
  public void addItem(ItemFile item){
      dataList.add(item);
      fireTableDataChanged();
  }
  public ItemFile getItem(int a) {
      return dataList.get(a);    
  }
  public  List<ItemFile> getList(){
      return dataList;
  }   
  public void clearList() {
      dataList.clear();
      fireTableDataChanged();
  }
} // end class

//snipet

        private MyTableModel tableModel = new MyTableModel();

        JTable table = new JTable(tableModel);
        table.setPreferredScrollableViewportSize(new Dimension(900, 400));
        table.setFillsViewportHeight(true);
        JScrollPane scrollPane = new JScrollPane(table);

Geoff, code end tags start with a /, not a \. So it's [/code], not [\code]. I've fixed it for you.

Moving to the Swing forum.

Thank, I found an error in the controller.
