Deprecated warnings?

[Josep_16]

Hello. I was just trying to compile this applet (taken from a tutorial):

/**
 * Applet Ojo
 *
 * <APPLET CODE="Ojo.class" WIDTH="300" HEIGHT="300">
 *   <PARAM NAME="Cadena" VALUE="Esto sí que es chulo">
 * </APPLET>
 */

import java.applet.Applet;
import java.awt.*;

public class Ojo extends Applet {
  int ancho, alto, anchoOjo, altoOjo, anchoPupila, altoPupila;
  int xOjo, yOjo, xPupila, yPupila, xActual, yActual;
  Image buffer;
  Graphics pantallaVirtual;
  public void init() {
    ancho = getBounds().width;
    alto = getBounds().height;
    anchoOjo = ancho / 2;
    altoOjo = alto / 2;
    anchoPupila = anchoOjo / 2;
    altoPupila = altoOjo / 2;
    xOjo = anchoOjo - anchoPupila;
    yOjo = altoOjo - altoPupila;
    xPupila = xOjo + anchoPupila/2;
    yPupila = yOjo + altoPupila/2;
    xActual = xPupila;
    yActual = yPupila;
    buffer = createImage(ancho, alto);
    pantallaVirtual = buffer.getGraphics();
  }
  public void paint(Graphics g) {
    g.setColor(Color.yellow);
    g.fillOval(xOjo, yOjo, anchoOjo, altoOjo);
    g.setColor(Color.black);
    g.fillOval(xActual, yActual, anchoPupila, altoPupila);
  }
  public void update(Graphics g) {
    Color colorTemporal = pantallaVirtual.getColor();
    pantallaVirtual.setColor(Color.white);
    pantallaVirtual.fillRect(0, 0, ancho, alto);
    pantallaVirtual.setColor(colorTemporal);
    paint(pantallaVirtual);
    g.drawImage(buffer, 0, 0, this);
  }
  public boolean mouseMove(Event evt, int x, int y) {
    xActual = (xPupila*21 + x*8)/32;
    yActual = (yPupila*21 + y*8)/32;
    repaint();
    return true;
  }
}

When I imputed "javac Ojo.java" it sent me the next error:

Note: Ojo.java uses or overrides a deprecated API.
Note: recompile with -Xlint:deprecation for details

Recompiling with "javac -Xlint:deprecation Ojo.java" it says:

Ojo.java:47: warning: [deprecation] mouseMove(java.awt.Event,int,int) in Java.awt.Component has been deprecated
         public boolean [B]m[/B]ouseMove(Event evt, int x, int y) {

What's wrong with the code? Thanks!

What's wrong with the code?

The code is using OLD methods that the current JDK developers don't think should be used any more.
Often that is because there are problems with using those old methods or because there are newer and better ways to do the job.
If you read the API code for the deprecated methods, there will be recommendations for better techniques.
