I need text area help

[edlover]

OK I have an applet with three panels, North Center and South. North and
Center each contain a TextArea and South contains a label and two buttons.
I want to reverse the text in North and set it in center when one of the
buttons get clicked.Can anyone Look at the code and tell me what I am missing:


import java.applet.*;
import java.awt.*;
import java.awt.event.*;

public class Encryption extends Applet implements ActionListener

{
TextArea firstTextArea;
TextArea secondTextArea;
Button firstButton;
Button secondButton;
public void init()
{
firstTextArea = new TextArea();

secondTextArea = new TextArea();

Panel p1=new Panel();
p1.setLayout(new FlowLayout());
p1.add(firstTextArea);

Panel p2=new Panel();
p2.setLayout(new FlowLayout());
p2.add(secondTextArea);
secondTextArea.setEditable(false);
Panel p3=new Panel();
p3.add(new Label("Welcome to Encryption",Label.LEFT));

setLayout(new BorderLayout());
add("North",p1);
add("Center",p2);
add("South",p3);

firstButton = new Button("CLEAR");
secondButton = new Button("ENCRYPT");
p3.add(firstButton);
firstButton.addActionListener(this);
p3.add(secondButton);
secondButton.addActionListener(this);
}
public void actionPerformed(ActionEvent e)
{
String actionCommand = e.getActionCommand();
if (actionCommand.equals("Encrypt"))
{
StringBuffer reverseText = new StringBuffer();
String cypherText = new String();


cypherText = (firstTextArea.getText().trim());


reverseText.append(cypherText);
reverseText.reverse();

//Store results of reversal back in original String
cypherText = reverseText.toString();
secondTextArea.setText(cypherText);

}
else if (actionCommand.equals("Clear"))
{
firstTextArea.setText("");
secondTextArea.setText("");
}
}

}
