Hello,

I'm trying to sort files in the data folder regarding their size. I made a list from a java function which has a filter (regarding file type for example ".jpg") and stores the list in a string[] (called fileList[])

I'm loading this file into a Pimage so I can acces its width and height and really sort comparin my sketch size

I'm doing this

1. 
   String[] fileList  ;
   String[] svgList  ;
   String[] lesmasquesX ;
   String[] lesmasquesM ;
   String[] lesmasquesS ;
   
   int indexmasque = 0;
   int indexmasqueS = 0;
   int indexmasqueM = 0;
   int indexmasqueX = 0;
   
   
   ...and later in the setup ...
   
   
     String path = sketchPath + "/data";
     fileList = listFileNames(path, txtFilter); //images
     svgList = listFileNames(path, svgFilter); //fichiers SVG
    
     println("nombre de fichiers jpg : " + fileList.length);
     println("nombre de fichiers svg : " + svgList.length);
     println
     for (int i = 0; i < fileList.length; i++) {
      
       println("element de fileList : " + fileList[i] + " & i= "+ i);
       imcompare = loadImage(fileList[i]);
   
       if (imcompare.width == width && imcompare.height == height){
         lesmasquesM[indexmasqueM] = fileList[i]; // where the error stands
         indexmasqueM++;
       }
       if (imcompare.width < width && imcompare.height < height){
         lesmasquesS[indexmasqueS] = fileList[i];
         indexmasqueS++;
       }   
       if (imcompare.width > width || imcompare.height > height){
         lesmasquesX[indexmasqueX] = fileList[i];
         indexmasqueX++;
       }   
      
     }
   

I'm getting a null Pointer exception and cannot really figure why

is there something wrong with
      String[] lesmasquesM ;
should be
      String[] lesmasquesM (); //??? ;)
?

I dont get it
