Hi,
I'm trying to limit the length of an array loaded with loadStrings().
For best performance I have to analyze only the 20 first lines of documents (.pdf files) who have more than 7 thousands of lines.
 

I saw this topics so I try this :

1. InputStream is = createInput("theUrlOfMyPdfDocument");
   String line = null;
   try
   {
     BufferedReader reader = new BufferedReader(new java.io.InputStreamReader(is, "UTF-8"));
     while ( lines.size() < 20)
     {
       lines.add(line);  
     }
   }
   catch (IOException e)
   { 
     e.printStackTrace();
   }
   
   println(lines.size()); // print 20
   println(lines[0].get()); // don't work
   
   exit();
   

it looks OK, but after I don't manage to see and use the content of these first lines : I'm new with ArrayList...
thanks
