@Override
public Object getValueAt(int rowIndex, int columnIndex) {
    Object obj = null;

    if(columnIndex==4)
       {
    setTotal(list.get(rowIndex));
    }
             switch (columnIndex){
        case 0: obj= list.get(rowIndex).getCode() ;break;
        case 1: obj=list.get(rowIndex).getDescription(); break;
        case 2: obj=list.get(rowIndex).getQuantity();break;
        case 3: obj=list.get(rowIndex).getPrice();break;            
        case …
