TextField loading

Hello everyone :)

So I have this program :

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

public class StrikerFrame extends Frame implements ActionListener{

Button btnGo, btnBack;
List lstStrikers;
Label lblName;
TextField txtPlayer;

public StrikerFrame(){

setLayout(null);

btnBack = new Button ("BACK <");
btnBack.addActionListener(this);
btnGo = new Button("GO >");
btnGo.addActionListener(this);
lstStrikers = new List(19);
lstStrikers.addActionListener(this);
lblName = new Label("NOW CHOOSE YOUR FAVOURITE STRIKER:::");
txtPlayer = new TextField();
txtPlayer.setEditable(false);

try{

FileReader fr = new FileReader("Strikers.txt");
Scanner s = new Scanner(fr);

while(s.hasNext()){
String line = s.nextLine();
lstStrikers.add(line);
}
s.close();
}catch(Exception e){
System.out.println("FAILED");
}

lstStrikers.setBounds(100,100,600,325);
btnBack.setBounds(500,525,100,50);
btnGo.setBounds(200,525,100,50);
lblName.setBounds(100,50,700,50);
txtPlayer.setBounds(100,450,700,50);

try{
FileReader fread = new FileReader("Strikers.txt");
Scanner scan = new Scanner(fread);

char z = lstStrikers.getSelectedIndex();
String sLine = scan.readLine(z);
txtPlayer.add(sLine);

scan.close();
}catch(Exception e){
System.out.println("FAILED");
}

add(lstStrikers);
add(btnBack);
add(btnGo);
add(lblName);
add(txtPlayer);

}

public void actionPerformed(ActionEvent ae){
if(ae.getSource()==btnBack){
setVisible(false);
}else if(ae.getSource()==btnGo){
System.exit(0);
}
}

}

And the thing I don't know is where i have the Bold text.
The program will show a list of Players and the person will choose the player by clicking on him from the list.
Therefore I want that the player chosen will be shown in a Textfield underneath the list and show the user which player he chose.
I don't know exactly what to do :S
(I use java awt :P)

Thanks very much for this useful forum :)
