highlight jtable row fro past due date reminder

This is employee data information. I have the contact starting date and expiration date, so I want to know how I can highlight a row in the jtable if there is a contact that will expire in one month or less.

enter image description here

Thank you

You can override the prepareRenderer(...) method of Table to highlight the entire row based on the data in the row:

JTable table = new JTable( model )
{
    public Component prepareRenderer(TableCellRenderer renderer, int row, int column)
    {
        Component c = super.prepareRenderer(renderer, row, column);

        if (!isRowSelected(row))
        {
            Date date = getModel().getValueAt(row, ???);

            if (date expires in one month)
                c.setBackground( someColor );
            else
                c.setBackground( getBackground() );
        }

        return c;
    }
};
