Android ArrayList without first value

I have problem with ArrayList. I have the question files structure like:

Y aaaaaa.

Y bbbbbb.

N ccccccc.

N ddddddd.

and I want to put into textview3 the first letter like Y or N

public void value (){

        Scanner answerScanner = new Scanner(getResources().openRawResource(R.raw.answer));
         Scanner questionScanner = new Scanner(getResources().openRawResource(R.raw.question));

        ArrayList<String> answerList = new ArrayList<String>();
          ArrayList<String> questionList = new ArrayList<String>();

           try {
               while (answerScanner.hasNextLine() ) {
                   answerList.add(answerScanner.nextLine());  
                   questionList.add(questionScanner.nextLine()); 
               }
           } finally {
               answerScanner.close();  
               questionScanner.close();
           }  

           int nextInt = random.nextInt(questionList.size());

           String answerString = answerList.get(nextInt);
           String questionString = questionList.get(nextInt);

           yourAnswerString = answerString.substring(0);
           yourQuestionString = questionString.substring(2);
           shortform = questionString.substring(0,1);


           TextView textGenerateNumber = (TextView)findViewById(R.id.textView1);
           TextView textGenerateNumber2 = (TextView)findViewById(R.id.textView2);
           TextView textGenerateNumber3 = (TextView)findViewById(R.id.textView3);
           textGenerateNumber.setText(yourQuestionString);
           textGenerateNumber2.setText(yourAnswerString);
           textGenerateNumber3.setText(shortform);
       }

then I add:

shortform = questionString.substring(0,1);
TextView textGenerateNumber3 = (TextView)findViewById(R.id.textView3);
textGenerateNumber3.setText(shortform);

I get good answers I all cases without first .... when radom get first line from text file I get empty value ( my textView3 are empty).
