Java SE (Java Platform, Standard Edition)

Hi everybody,
I'm developing the first Applets, I made a window extending Frame class and I used KeyListener to write on it from keyboard.
I'd like to have a method that resize the text creating a new paragraph everytime the text exceed the width of the window, such
a common Text Editor.

Do you know such a method or how I can realize one to accomplish this task?

Thanks in advance,
Paolo F.C.

P.S. here is my code :

*******************************************
package com.testapplet;

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

public class Window extends Frame
{
	
	public String testo = "";
	public Ascoltatore asc;
	public AscoltaTastiera asc_tast;
	
	public static void main(String argv[])
	{
		Window wind = new Window();
	}
	
	Window()
	{
		setBounds(0,0,800,600);
		setTitle(getClass().getName());
		setVisible(true);
	    setBackground(Color.white);
	    setForeground(Color.black);
		asc = new Ascoltatore();
		asc_tast = new AscoltaTastiera(this);
		addWindowListener(asc);
		addKeyListener(asc_tast);
	}
	
	public void paint(Graphics g)
	{
		testo = asc_tast.testo;
		g.drawString(testo, 10, 22+14);
	}
}

*******************************************
package com.testapplet;

import java.awt.event.*;

public class Ascoltatore extends WindowAdapter
{
	public void windowClosed (WindowEvent evt)
	{
		System.out.println(evt);
		System.exit(0);
	}
	public void windowClosing (WindowEvent evt)
	{
		evt.getWindow().dispose();
		System.out.println(evt);
	}
	
}

*********************************************
package com.testapplet;

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

public class AscoltaTastiera implements KeyListener
{
	public String testo = "";
	public Frame parent;
	public AscoltaTastiera(Frame frame)
	{
		this.parent = frame;
	}
			public void keyPressed(KeyEvent e)
			{}
			public void keyReleased(KeyEvent e)
			{}
			public void keyTyped(KeyEvent e)
			{
				testo += e.getKeyChar();
				if (testo != null)
			    parent.repaint();
			}
		}
