Displaying text in textarea with a button

[brendan89]

Hi, I am new to Java and I am trying to figure out how to do this: "Create two text areas - one that will hold user input of names and another that will display the names sorted after having pressed a button." The part I'm stuck at is getting the text to display in the text area on the right. What am I doing wrong?

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

public class ClassFrame extends JFrame
{
private JPanel panel1;
private JPanel panel2;
private JPanel panel3;
private JTextArea nameText;
private JTextArea sortedText;
private JButton sort;
private String list = "";
private String[] nameArray;
public ClassFrame()
{
setTitle("Class Frame");
setLayout(new BorderLayout(2,2));
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
sort = new JButton("Sort");

nameText = new JTextArea(20,20);
sortedText = new JTextArea(20,20);

panel1 = new JPanel();
panel2 = new JPanel();
panel3 = new JPanel();

panel1.add(nameText);
panel2.add(sortedText);
panel3.add(sort);

add(panel1, BorderLayout.WEST);
add(panel2, BorderLayout.EAST);
add(panel3, BorderLayout.SOUTH);



sortText(nameText.getText());

sort.addActionListener(new SortButtonListener());

pack();
setVisible(true);
}

public void sortText(String names)
{
String delim = "\n";
nameArray = names.split(delim);
Arrays.sort(nameArray);
}

private class SortButtonListener implements ActionListener
{
public void actionPerformed(ActionEvent e)
{
if(e.getActionCommand().equals("sort"))
{
for(int index = 0; index<nameArray.length; index++)
sortedText.append(nameArray[index] + "\n");
}

}
}

public static void main(String[] args)
{
ClassFrame show = new ClassFrame();
}
}
