Dear Java experts,

I have a JTable problem here.
Problem description: I have to display a default table(3X3) when the
application launches for the first time. Then user should able to
modify the table and my application should able to read the changed
values in this table. Please have a look at the below code.

Table3.addActionListener(new ActionListener(){
          public void actionPerformed(ActionEvent e){

              for(int i = 0; i < 3; i++){
                   for(int j = 0; j < 3; j++){
                       try{
                            t3[i][j] =
((Integer)data3[i][j]).intValue();
                       }catch(ClassCastException cce){}
                   }
              }
              table3.getModel().addTableModelListener(new
TableModelListener(){
                  public void tableChanged(TableModelEvent e) {
                      int row = e.getFirstRow();
                      int column = e.getColumn();
                      TableModel model = (TableModel)e.getSource();
                      String columnName = model.getColumnName(column);
                      Object data3 = model.getValueAt(row, column);
                      t3[row][column] = new
Integer((String)data3).intValue();
               }
              });
          }
       });

here table3 is a JTable
      Table3 is the radio button used to select that matrix
      data3 is an Object[][] with column names for JTable
      t3 is the default matrix used and modified by the user.

When I use this code, my application throwing ClassCastException
because of converting data3 to t3. Can any body help me?
