Currency Converter Applet Help...

[MarkL410]

Hello there, I am in the process of creating a currency converter applet. I have the layout done and the applet runs in my web browser but I am having trouble coding the calculation for the converter. Could somebody point me in the right direction please, here is my code...

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class CurrencyConverter extends JApplet implements ActionListener
  {
   // applet title   
   JLabel lblTitle = new JLabel ("Currency Converter Applet");
   
   // label for promt input + input box
   JLabel lblinput = new JLabel("Enter a Value GBP");
   JTextField txtinput = new JTextField(10);

   
  
   // Labels to display name of currency converter
   JLabel lbldollar = new JLabel("US Dollars = ");  
   JLabel lbleuro = new JLabel("Euro = ");
   JLabel lblyen = new JLabel("Yen = ");
   JLabel lblpound = new JLabel("GBP = ");

   // Labels to display value of currency converted
   JLabel lbldollaramount = new JLabel("0");
   JLabel lbleuroamount = new JLabel("0");
   JLabel lblyenamount = new JLabel("0");
   JLabel lblpoundamount = new JLabel("0");
   
   // button convert + clear
   JButton btnconvert = new JButton ("Convert");
   JButton btnclear = new JButton ("Clear");
     
public void init()
{
        // this is a workaround for a security conflict with some browsers
        // including some versions of Netscape & Internet Explorer which do 
        // not allow access to the AWT system event queue which JApplets do 
        // on startup to check access. May not be necessary with your browser. 
        JRootPane rootPane = this.getRootPane();    
        rootPane.putClientProperty("defeatSystemEventQueueCheck", Boolean.TRUE);
    
        // provide any initialisation necessary for your JApplet
}

  public void start()
    {
        // provide any code required to run each time 
        // web page is visited 
        display(); 
    }
    
public void display()
{  
  /**
   * set font size and colour of labels
  */
  // lblinput
  lblinput.setFont(new Font("Algerian", Font.BOLD, 18));
  lblinput.setForeground(Color.black);
  
  txtinput.setFont(new Font("Algerian", Font.BOLD, 18));
  txtinput.setForeground(Color.black);
  
  //dollar
  lbldollar.setFont(new Font("Algerian", Font.BOLD, 18));
  lbldollar.setForeground(Color.black);
  
  lbldollaramount.setFont(new Font("Algerian", Font.BOLD, 18));
  lbldollaramount.setForeground(Color.black);
  
  //euro
  lbleuro.setFont(new Font("Algerian", Font.BOLD, 18));
  lbleuro.setForeground(Color.black);
  
  lbleuroamount.setFont(new Font("Algerian", Font.BOLD, 18));
  lbleuroamount.setForeground(Color.black);
  
  //yen
  lblyen.setFont(new Font("Algerian", Font.BOLD, 18));
  lblyen.setForeground(Color.black);
  
  lblyenamount.setFont(new Font("Algerian", Font.BOLD, 18));
  lblyenamount.setForeground(Color.black);
  
  //gbp
  lblpound.setFont(new Font("Algerian", Font.BOLD, 18));
  lblpound.setForeground(Color.black);
  
  lblpoundamount.setFont(new Font("Algerian", Font.BOLD, 18));
  lblpoundamount.setForeground(Color.black);
  
  //buttons font, size, colour  and attach action listener
  
  btnconvert.setFont(new Font("Algerian", Font.BOLD, 18));
  btnconvert.setForeground(Color.black);
  btnconvert.addActionListener(this);
  
  btnclear.setFont(new Font("Algerian", Font.BOLD, 18));
  btnclear.setForeground(Color.black);
  btnclear.addActionListener(this);
   
  /**
   * add items to main panel
   */

   Container content = getContentPane();
  // set layout
  content.setLayout(new GridLayout(6,2));
  // set colour
  content.setBackground(Color.red);
  
  // (input)
  content.add(lblinput);
  content.add(txtinput);
  txtinput.setText("0");
  
  // (dollar)
  content.add(lbldollar);
  content.add(lbldollaramount);
  
  //(euro)
  content.add(lbleuro);
  content.add(lbleuroamount);
  
  //(yen)
  content.add(lblyen);
  content.add(lblyenamount);
 
  //(pound)
  content.add(lblpound);
  content.add(lblpoundamount);
  
  content.add(btnclear);
  content.add(btnconvert);

   }
   
     public void actionPerformed(ActionEvent event)
     {   
       if(event.getSource()==btnclear)
         {txtinput.setText("0");   
          lbldollaramount.setText("0");
          lbleuroamount.setText("0");
          lblyenamount.setText("0");
          lblpoundamount.setText("0");}
          
          if(event.getSource()==btnconvert)
         {txtinput.setText("1");   
          lbldollaramount.setText("1");
          lbleuroamount.setText("1");
          lblyenamount.setText("1");
          lblpoundamount.setText("1");}
          
        }
    }

Thanks in advance.
