static JTextField txtPrincipal, txtRate;
static JLabel lblPrincipal, lblRate, lblInterest;
// main function
public static void main(String args[])
{
// create a frame
f = new JFrame("Interest Calculator");
InterestCalculator c = new InterestCalculator();
// create a textfield
txtPrincipal = new JTextField(16);
txtRate = new JTextField(16);
// create label field
lblPrincipal=new JLabel("Principal
Amount:");
lblRate=new JLabel("Rate of
Interest");
lblInterest = new JLabel("

// create number buttons and some operators
JButton butSubmit;
// create number buttons
butSubmit = new JButton("Calculate");
// create a panel
JPanel p = new JPanel();
// add action listeners
butSubmit.addActionListener(c);
// add elements to panel
p.add(lblPrincipal);
p.add(txtPrincipal);
p.add(lblRate);
p.add(txtRate);
p.add(lblInterest);
p.add(butSubmit);
// add panel to frame
f.add(p);
