      Double sum = 0.0;
        
      for(double i=0; i<jTable1.getRowCount(); i++)
      {

 sum = sum + Double.parseDouble(jTable1.getValueAt((int)i,1).toString());
      }
        txtbill.setText(Double.toString(sum));

Balance Calculation

    private void txtpayKeyReleased(java.awt.event.KeyEvent evt) 
   {                                   
        Double pay,total,bal;
        pay = Double.parseDouble(txtpay.getText());
        total = Double.parseDouble(txtbill.getText());
        bal = pay - total;
        txtbal.setText(String.valueOf(bal));  
   }
