This is the third time this has been asked (and answered twice) in the past week. Is this homework somewhere?

Hi! I have a class that read only image from a directory ( relative to sketch folder ) and read all colour picture data.

this is the function that read the list
Quote:


/*METODOS PRIVADOS-----------------------------------------------------------------*/
 private String [] leerDirectorio(String _path){
   if (isDir) {
     dir = new File(dataPath(_path));  
   }
   else
   {
     dir = new File(_path);  
   }
   String[] children =  dir.list(new PicFilter());
   if (children == null) {
     //println("*******  error en la lectura del directorio >>"+_path);
   }  
   else {
     //println("*******  list >>"+_path +"children.length:"+children.length);    
     for (int i=0; i<children.length; i++) {
       children[i] = _path + children[i];
       println("*******  paleta["+i+"] >>"+children[i]);  
     }
   }  
   return children;

 }



I had to use some java functions, copy here , If someone thinks that this  class could be better, please, say me!

here are the entire class and example!
