        int qty = Integer.parseInt(txtqty.getValue().toString());
        int price = Integer.parseInt(txtprice.getText());
        int tot = qty * price;
        
        txtamount.setText(String.valueOf(tot));
        
    }

Paste Code Inside the Add Button

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {                                         

        DefaultTableModel model = new DefaultTableModel();
        model = (DefaultTableModel)jTable1.getModel();
        model.addRow(new Object[]
                
        {
            txtpcode.getText(),
            txtpname.getText(),
            txtqty.getValue().toString(),
            txtprice.getText(),
            txtamount.getText(),

            int sum = 0;
                    
        for(int i = 0; i<jTable1.getRowCount(); i++)
        {

           txtprice.setText("");
           txtamount.setText("");
        txtpcode.requestFocus();
    }

Design the Bill

public void bill()
    {
        String total = txtotal.getText();
         String pay = txtpay.getText();
         String bal = txtbal.getText();
         
          DefaultTableModel model = new DefaultTableModel();
        
        model = (DefaultTableModel)jTable1.getModel();
         
         txtbill.setText(txtbill.getText() + "******************************************************\n");
         txtbill.setText(txtbill.getText() + "           POSBILL                                     \n");
         txtbill.setText(txtbill.getText() + "*******************************************************\n");
         
         //Heading
          txtbill.setText(txtbill.getText() + "Product" + "\t" + "Price" + "\t" + "Amount" + "\n"  );
          
          
          for(int i = 0; i < model.getRowCount(); i++)
          {
              
              String pname = (String)model.getValueAt(i, 1);
              String price = (String)model.getValueAt(i, 3);
              String amount = (String)model.getValueAt(i, 4); 
              
           txtbill.setText(txtbill.getText() + pname  + "\t" + price + "\t" + amount  + "\n"  );
    
          }
          
          txtbill.setText(txtbill.getText() + "\n");     
          
          txtbill.setText(txtbill.getText() + "\t" + "\t" + "Subtotal :" + total + "\n");
          txtbill.setText(txtbill.getText() + "\t" + "\t" + "Pay :" + pay + "\n");
          txtbill.setText(txtbill.getText() + "\t" + "\t" + "Balance :" + bal + "\n");
          txtbill.setText(txtbill.getText() + "\n");
          txtbill.setText(txtbill.getText() + "*******************************************************\n");
          txtbill.setText(txtbill.getText() + "           THANK YOU COME AGIN             \n");

        
    }

 

Paste the code inside the Bill button

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) 
   {                                         
       Balance();
       bill();

        try 
        {
            txtbill.print();
        } 
        catch (PrinterException ex) {
            Logger.getLogger(pos.class.getName()).log(Level.SEVERE, null, ex);
