Exception in thread "main" java.lang.IndexOutOfBoundsException in Java

Question

I know that is an error that has already been asked many times, but I can't find where I have the problem. The error It is shown is the following:

Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 393, Size: 393
at java.util.ArrayList.rangeCheck(ArrayList.java:653)
at java.util.ArrayList.get(ArrayList.java:429)
at scraping.complementos_juegos.main(complementos_juegos.java:305)

There are many things I don't understand. The first line, where it shows Index: 393, Size: 393, what does that mean? The index and size of the array?

Let's go to the code:

1.- I scrap more than 2.700 links that are saved in an array called all_links. As I want to store a lot of information I am using a bidimensional ArrayList called listaEmpresaA:

ArrayList<ArrayList<String>> listaEmpresaA = new ArrayList<ArrayList<String>>();

    String [] paises = {"USA"};

    int total_columnas = 2 + (paises.length*3);

    //CREATING THE COLUMS
     for(int i =0; i< total_columnas; i++){
                listaEmpresaA.add(new ArrayList<String>());
            }

     //DEFINITION OF THE ROWS


     //<--------------- START OF THE HEADER DEFINITION

     listaEmpresaA.get(0).add("Juego");
     listaEmpresaA.get(1).add("URL");



     for (z=0 ; z<paises.length; z++) {
         for (int j=2; j<total_columnas ; j=j+3 ) {
             listaEmpresaA.get(j).add(paises[z]);
             listaEmpresaA.get(j+1).add(paises[z] + " Gold");
             listaEmpresaA.get(j+2).add(paises[z] + " sin Gold");
         }
     }

    int filas = 1; //JUST TO KNOW THE AMOUNT OF ROWS I HAVE

     //<--------------- FINISH OF THE HEADER DEFINITION


    //<--------------- STARTING OF THE SCRAPING FOR EACH LINK

    int contador_juegos = 1;

    for (String link : all_links) {

     String urlPage = "https://www.microsoft.com" + link;
     System.out.println(contador_juegos + ".- Comprobando entradas de: "+urlPage);

     if (getStatusConnectionCode(urlPage) == 200) {

         Document document = getHtmlDocument(urlPage);

         Elements entradas = document.select("div.page-header div.m-product-detail-hero-product-placement div.context-product-placement-data");

         for (Element elem : entradas) {
             String titulo = elem.getElementsByClass("c-heading-2").text();

             System.out.println(titulo+"\n");
             listaEmpresaA.get(0).add(titulo);
             listaEmpresaA.get(1).add(urlPage);

         }

         entradas = document.select("div.price-info");

         for (Element elem : entradas) {
             String titulo = elem.getElementsByTag("s").text();

             System.out.println("Precio base: " + titulo+"\n");
             listaEmpresaA.get(2).add(titulo);

         }

         entradas = document.select("div.price-info");

         for (Element elem : entradas) {
             String titulo = elem.getElementsByClass("price-disclaimer").text();

             System.out.println("Precio para los miembros sin GOLD: " + titulo+"\n");
             listaEmpresaA.get(3).add(titulo);


         }

         entradas = document.select("dd.cli_upsell-options div.cli_upsell-option");

         // Paseo cada una de las entradas
         for (Element elem : entradas) {
             String titulo = elem.getElementsByClass("price-disclaimer").text();

             System.out.println("Precio para los miembros GOLD: " + titulo+"\n");
             listaEmpresaA.get(4).add(titulo);

         }

         filas++;

     }

     contador_juegos++;
    }


    //<--------------- FINISH OF THE SCRAPING FOR EACH LINK BAZAR USA   

2.- Create the Excel and store the information from listaEmpresaA arrayList to the Excel.

try {
         //create .xls and create a worksheet.
         FileOutputStream fos = new FileOutputStream("D:\\mierda.xls");
         HSSFWorkbook workbook = new HSSFWorkbook();
         HSSFSheet worksheet = workbook.createSheet("XboxOne");

            int l=0;

                //CREATING EXCEL ROWS
             for (int f=0; f< filas ; f++) {
                HSSFRow fila = worksheet.createRow(f);

                //CREATING EXCEL COLUMNS
                for(int c=0;c<total_columnas;c++){
                       HSSFCell celda = fila.createCell(c);
                       celda.setCellValue(listaEmpresaA.get(c).get(f)); //<----- THIS IS THE LINE 305 WHERE I HAVE THE ERROR
                       l++;

                }      
             }

        //Save the workbook in .xls file
         workbook.write(fos);
         fos.flush();
         fos.close();
     } catch (FileNotFoundException e) {
         e.printStackTrace();
     } catch (IOException e) {
         e.printStackTrace();
     }

I have many questions and I would really appreciate if you could give me some tips so that I can find the solution my-self:

1.- I don't understand why it is shown the problem at this point Index: 393, Size: 393 when the program has been running until the index 2730 of the total links (2.751 links in total). The last data shown on the console is:

2730.- Comprobando entradas de: https://www.microsoft.com/en-us/store/p/star-wars-pinball-season-1-bundle/brz3mqfjnlmw Star Wars™ Pinball Season 1 Bundle

Precio base:

Precio para los miembros sin GOLD:

Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 393, Size: 393 at java.util.ArrayList.rangeCheck(ArrayList.java:653) at java.util.ArrayList.get(ArrayList.java:429) at scraping.complementos_juegos.main(complementos_juegos.java:305)

2.- When I use the for-each bucle, I have realized that it is not exactly following the order set on the array. I don't know why.

3.- The program spends 1 hour just to scrap information from one store, and I want to store more than 50, ¿is there a way to reduce this time? I have read something about "HashMap" but I don't know how to use them. Anyway if it is a better solution I will take a look.

Thanks in advance!

Have a good day.
