Problema di ereditarietà nei metodi

[Lory1990]

Ciao a tutti!
Vorrei sottoporvi questo quesito semplice semplice: ho creato al seguente classe

package Utility;

import javax.swing.JPanel;
import processing.core.PApplet;
/**
 *
 * @author Lorenzo De Francesco
 */
public class Plane3D extends PApplet {
    
    @Override
     public void setup(){
        background(255);
        addMouseWheelListener(new java.awt.event.MouseWheelListener() {
            @Override
            public void mouseWheelMoved(java.awt.event.MouseWheelEvent evt) {
                mouseWheel(evt.getWheelRotation());
        }});
    }
    @Override
    public void draw(){
        background(255);
        scaleUp = wheel;
        transScale(mouseX, mouseY, scaleUp);
    }; 
    private float scaleUp = 0.5f;
    private float wheel =  1.0f;
    private float wheelMult = 0.10f;
    private float x;
    private float y;
    private float xOffset;
    private float yOffset;
    private float xold;
    private float yold;
    private float xpiv;
    private float xpivOld;
    private float ypiv;
    private float ypivOld;
    
    private void mouseWheel(int step) {
      wheel=constrain((float)wheel+step*wheelMult*-1,(float)0.1,(float)50);
    }
    private void transScale(float x, float y, float scale) {
        if (mousePressed == true) {
        xOffset = x-xold;
        yOffset = y-yold;
        xpiv = (xpivOld-xOffset/scaleUp);
        ypiv = (ypivOld-yOffset/scaleUp);
        xpiv = xpiv + (xOffset/scaleUp);
        ypiv = ypiv + (yOffset/scaleUp);
        xpivOld = xpiv;
        ypivOld = ypiv;
        xold = x;
        yold = y;
        }
        else{
        xOffset = x-xold;
        yOffset = y-yold;
        xpiv = (xpivOld-xOffset/scaleUp);
        xpivOld = xpiv;
        ypiv = (ypivOld-yOffset/scaleUp);
        ypivOld = ypiv;
        xold = x;
        yold = y;
        }
        // blue grid position
        translate(x, y);
        scale(scale);
        strokeWeight(2);
        stroke(70);
        strokeWeight(2);
        // negate mouse position
        translate(xpiv, ypiv);
    }
    
    public JPanel getJPanel(){
        JPanel panel = new JPanel();
        panel.add(this);
        this.init();
        return panel;
    }
}

ed una classe che la estende

package Decks;

import Utility.Plane3D;

/**

 * @author Lorenzo De Francesco
 */
public class Plot3D extends Plane3D{

    
    private double a [][];
    public Plot3D(){
        a = new double[3][4];
        a[0][0] = 1;
        a[0][1] = 2;
        a[0][2] = 3;
        a[1][0] = 1;
        a[1][1] = 5;
    }
    @Override
    public void setup(){
        size(400, 400);
    }
    @Override
    public void draw(){
        fill(123,23,45);
        ellipseMode(CENTER);
        ellipse(32,65,40,40);
    };
    
   
}

ecco io ho fatto l'overrride dei metodi setup() e draw() ma vorrei che in questi metodi venisse prima eseguito il codice della classe madre e poi quello che scrivo io nella classe figlia...
Come si fa?

Usa super.

@Override
public void setup() 
{
    super.setup();

    size(400, 400);
}
