hello,ihad tihs error when i run my project ; the error appear in this level on my script

public void doQRPatient() { 
     System.out.println("methode patien dcm"); 
        String cmd = ""; 
        MyParser parser = new MyParser(); 
        Vector total1 = new Vector(); 
        Vector total2 = new Vector(); 
        Vector total3 = new Vector(); 
        try { 
            cmd = userDir + BIN_DCMQR + java.util.ResourceBundle.getBundle("pacs/resources/Strings").getString("_-R_00080090_-R_00100010_-R_00100020_-R_00081030_") + " " + aeTitle + "@" + address + ":" + port; 
            System.out.println("COMANDO 1:" + cmd); 
            total1 = executer(cmd); 
            for (int i = 0; i < total1.size(); i++) { 
                System.out.println(i+".-\t"+(String)total1.elementAt(i)); 
            } 
            System.out.println("app comb vec-ref"); 
            combineVectors1_referring_2(1, parser.parsePatient(total1.toArray()), parser.parseStudyUID(total1.toArray()), parser.parseNumberSeries(total1.toArray()), parser.parseNumberImages(total1.toArray()), parser.parseReferring(total1.toArray()), parser.parseStudyDesc(total1.toArray())); 
            parent.showMessage(java.util.ResourceBundle.getBundle("pacs/resources/Strings").getString("INICIADA_COMUNICACION_DICOM_CON_EL_NODO:_") + " "+aeTitle + "@" + address + ":" + port); 
        
       
        } catch (Exception err) { 
            err.printStackTrace(); 
            //parent.showMessage(java.util.ResourceBundle.getBundle("com/jjcp/resources/Strings").getString("HAOCURRIDOUNERROR")+aeTitle+"@"+address+":"+port); 
            parent.showMessage("ERROR :" + aeTitle + "@" + address + ":" + port); 
        } 
    }

and the error appear in this method exsactely in while boucle

private Vector executer(String cmd) { 
  Vector result = new Vector(); 
  try { 
                    System.out.println("method executer"); 
   Process p = Runtime.getRuntime().exec(cmd); 
   BufferedReader input = new BufferedReader(new InputStreamReader(p 
     .getInputStream())); 
   String line; 
   while ((line = input.readLine()) != null) 
    {result.addElement(line); 
                        System.out.println("line"); 
   }
input.close(); 
  } catch (Exception ex) { 
   ex.printStackTrace(); 
  } 
  return result; 
 }

because whene i run it in dont see the word "line" in my output
so if any one have an idea,please tell me .
beast regards .

If the process p has no endline terminators, then when it closes, line will be null, and so 'result' will be zero length. The 'toArray" commands in doQRPatient will result in arrays of zero length. I'm guessing that 'MyParser' is not properly handling the degenerate case of zero length arrays.

so i tyr to read the first element of an empty vector ;how can i resolved it??
and am sure that there is no problem with myparser:which the code is

public class MyParser {

MyParser() {
}

}

i think the problem is in execute method so can i resolve it

Before trying to access the elements of a Vector, call the 'size' method to verify that the Vector has enough elements. A zero length Vector is perfectly valid and ordinary. You can't simply assume it has elements in it.
