        {
            String mcrunch = "MIDWEEK CRUNCH";
            int  price = 1300;
            int  qty = Integer.parseInt(txtMC.getText());
            int tot = price * qty;   
            model = (DefaultTableModel)jTable1.getModel();
            
            model.addRow(new Object[]          
            {
                mcrunch,
                price,
                qty,
                tot 
            }        
             );    
        }
         if(chkCC.isSelected())
        {
           String crispy  = "CRISPY CHICKEN";
            int  price = 1800;
            int  qty = Integer.parseInt(txtCC.getText());
            int tot = price * qty;   
            model = (DefaultTableModel)jTable1.getModel();
            
            model.addRow(new Object[]          
            {
                crispy,
                price,
                qty,
                tot 
            }        
             );    
        }
         
          if(chkHD.isSelected())
        {
           String hotdeal  = "Hot Drumlet Deal";
            int  price = 2800;
            int  qty = Integer.parseInt(txtHD.getText());
            int tot = price * qty;   
            model = (DefaultTableModel)jTable1.getModel();
            
            model.addRow(new Object[]          
            {
                hotdeal,
                price,
                qty,
                tot 
            }        
             );    
        }

        for(int i=0; i<jTable1.getRowCount(); i++)
        {
            sum = sum + Integer.parseInt(jTable1.getValueAt(i, 3).toString());  
        }
        
        txtbill.setText(Integer.toString(sum));
