How to set a custom object in a JTable row

Question

I should tell this first, this is NOT about Rendering a Table cell.

Here is the TableModel that i\'m building using a 2D array based on a User object i

Answer 1

Instead of splitting the User object up before you create the model, add it directly to the model and allow the model to do the work for you...

For example

public class VstTableItemModel extends AbstractTableModel {

    private List<User> users;

    public VstTableItemModel(List<User> users) {

        this.users = new ArrayList<User>(users);

    }

    @Override
    public int getRowCount() {
        return users.size();
    }

    @Override
    public int getColumnCount() {
        return 6;
    }

    @Override
    public Object getValueAt(int rowIndex, int columnIndex) {

        Object value = "??";
        User user = users.get(rowIndex);
        switch (columnIndex) {
            case 0:
                value = user.getUserUsername();
                break;
            case 1:
                value = user.getUserName();
                break;
            case 2:
                value = user.getUserPhone();
                break;
            case 3:
                value = user.getUserNic();
                break;
            case 4:
                value = user.getUserAddress();
                break;
            case 5:
                value = user.getUserEmail();
                break;
        }

        return value;

    }

    @Override
    public Class<?> getColumnClass(int columnIndex) {
        return // Return the class that best represents the column...
    }

    /* Override this if you want the values to be editable...
    @Override
    public void setValueAt(Object aValue, int rowIndex, int columnIndex) {
        //....
    }
    */

    /**
     * This will return the user at the specified row...
     * @param row
     * @return 
     */
    public User getUserAt(int row) {
        return users.get(row);
    }

}

This way, you should be able to do something like...

List<User> userList = userManagerService.getAllUsers();
VstTableItemModel tiModel = new VstTableItemModel(userList);

Now when you need to...you can grab a the user that is represent at a specific row...

User user = tiModel.getUserAt(rowIndex);
