I have 3 clases in the proyect:

Interficie

1. import controlP5.*;
   
   
   class Interficie extends PApplet{
   
   Cargador car;
   Slider slider;
   ControlP5 controlP5;
   
   
   void setup() {
     size(800,600);
     background(0);
   
   
     String folderPath = selectFolder();  // Opens file chooser
     if (folderPath == null) {
       // If a folder was not selected
       println("No folder was selected...");
     }
     else {
       // If a folder was selected, print path to folder
       println(folderPath);
     }
   
     car = new Cargador(folderPath+"");
     car.cargar();
   
     slider = new Slider(car.getImagenes(),this);
     controlP5 = new ControlP5(this);
     controlP5.addButton("Siguiente",0,100,100,80,19);
     controlP5.addButton("Anterior",255,100,120,80,19);
   }
   
   public void draw() {
     stroke(255);
     background(0);
   
     slider.display();
     image(slider.getImagenActual(),width/4,height/4,width/2,height/2);
   }
   /*public void mousePressed(){
    car.imagenSiguiente();
    }*/
   
   public void Siguiente(int valor) {
     slider.Siguiente(valor);
   }
   public void Anterior(int valor) {
     slider.Anterior(valor);
   }
   
   public void mousePressed() {
     slider.mousePressed();
   }
   

Cargador:

1. import java.util.ArrayList;
   
   
   
   public class Cargador {
     private ArrayList<PImage> imagenes;
     private String ruta;
     private int pos;
     private PImage imgAct;
   
     public Cargador(String ruta) {
       this.ruta = ruta;
      
     }
   
     public void cargar() {
       imagenes = new ArrayList();
       String[] nombres = listarArchivos(ruta);
       println(nombres);
       for(int i= 0; i< nombres.length;i++) {
         imagenes.add(loadImage(ruta+nombres[i]));
       }
       pos=0;
       imgAct =(PImage)imagenes.toArray()[0];
     }
    
     String[] listarArchivos(String dir) {
       File file = new File(dir);
       if(file.isDirectory()) {
         String names[] = file.list();
         return names;
       }
       else {
         return null;
       }
     }
   
     public void imagenSiguiente() {
       pos=(pos+1)%imagenes.size();
       imgAct = (PImage)imagenes.toArray()[pos];
     }
   
     public void imagenAnterior() {
       pos=(pos-1);
       if(pos<0) {
         pos=imagenes.size();
       }
     }
     public ArrayList<PImage> getImagenes(){
      return imagenes;
     }
   }

and Slider:

1. class Slider{
    
     ArrayList<PImage> imagenes;
     private int numImagenes;
     private int alto;
     private int separacionx,separaciony;
     private int posicion;
     private int imgAct;
     private float anchoImagen,altoImagen;
     private PApplet parent; 
    
    
    public Slider(ArrayList<PImage> imagenes,PApplet parent){
      this.imagenes = imagenes;
      this.numImagenes = (10 > imagenes.size() ? imagenes.size():10);
      this.alto = 100;
      this.separacionx = 20;
      this.separaciony=10;
      this.posicion = 0;
      this.imgAct=0;
      this.parent = parent;
     
     
   
       
     
    }
    
    void display(){
     
      parent.fill(255);
      parent.rect(0,height-this.alto,width,height);
      anchoImagen = ((width-(this.separacionx * (this.numImagenes+1)))/this.numImagenes);
      altoImagen = (alto-this.separaciony*2);
     
     
      for(int i = 0; i<numImagenes;i++){
       
       
      int nImg = (int)(mouseX/(anchoImagen+separacionx));
     println(mouseX);
      if(mouseY >height - alto+separaciony && mouseY <height-separaciony && mouseX > anchoImagen*nImg + separacionx*(nImg+1) && nImg == i+posicion){
      parent.image((PImage)imagenes.toArray()[i+posicion],(separacionx*(i+1)+(i*anchoImagen))-20,(height-alto+separaciony)-20,anchoImagen+40,altoImagen+40);
      }
     
       
     else{
        image((PImage)imagenes.toArray()[i+posicion],separacionx*(i+1)+(i*anchoImagen),height-alto+separaciony,anchoImagen,altoImagen);}
      }
    }
    
   public void Siguiente(int valor){
    
     if(posicion+numImagenes+1 < imagenes.size()){
       posicion++;
       println(posicion);
     }
    
   }
   public void Anterior(int valor){
   if(posicion>=1){
     posicion--;
     println(posicion);
   }
   }
   
   void mousePressed(){
     if(mouseY >height - alto+separaciony && mouseY <height-separaciony){
      int nImg = (int)(mouseX/(anchoImagen+separacionx));
      if(mouseX > anchoImagen*nImg + separacionx*(nImg+1)){
      imgAct = nImg;
      }
     
     }
    
   }
   
   PImage getImagenActual(){
     return (PImage)imagenes.toArray()[imgAct];
   }
   }

can anyone help me?
