Answer 1

mstrnew = new JButton //this should clear receipt
if(evnt.getSource()==mstrnew)
              order.setText("");
              price.setText("");
              total.setText("0.0");
              cash.setText("");
              change.setText("");
              mstrtotal = 0;
              JOptionPane.showMessageDialog(null,"              Starting New Transaction...","",JOptionPane.PLAIN_MESSAGE);    receipt.setText("");}
else if(evnt.getSource()==vm1)
              generate("           2pc. Chicken Strips Meal\n");
              order.setText("2pc. Chicken Strips");
              price.setText("61.0");
              mstrtotal = Double.parseDouble(price.getText()) + Double.parseDouble(total.getText());
              total.setText(String.valueOf(mstrtotal));
// scrollpane part
             receipt = new JTextArea();
             receipt.setEditable(true);
             //receipt.setLineWrap(true);
         up = "\n          YUM! Brands Corporation, Kentucky Fried Chicken ?\n                       KFC LaSalle Branch, Taft Ave., Manila\n\n           88788   TIN-209-670-390-002   REG VAT   POS#113\n           SN:41-HK170 All prices were subjected of 12% VAT.";
         mid = "\n\n";
         down = "\n";
         complete = up+mid+down;
         receipt.setText(complete);
         sp = new JScrollPane(receipt,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
public void generate(String z)
         mid += z;
         complete = up+mid+down;
