android - 算術例外

Question

これが私のJavaコードです。"Fatal Exception main"
アプリを正常に実行したいというエラーが発生しました。
私を助けてください。私はAndroidが初めてです

if(queList.size() == question_Counter+1) {


        //  answerList = new ArrayList<String>();
            final int count= dbhelper.getCorrectAnswerCount(answerList);
            count1=count;
            Log.d("bachhhaaaa**********", "Test Activity"+count1);


            String TotalMark  = dbhelper.totalMark();
            Log.d("TEST<<<<<<<<<<<<TotalMark", TotalMark);

            String NoOfQuestion =dbhelper.noOfQuestion();
            Log.d("TEST<<<<<<<<<<<<NoOfQuestion", NoOfQuestion);

            int perQuestionValue=0;
            perQuestionValue= Integer.parseInt(TotalMark) /Integer.parseInt(NoOfQuestion);


            int TotalCountMark=0;
            TotalCountMark = count1 * perQuestionValue;

            String answerString = "Answer";
            for(int i=0;i<answerList.size();i++){

                answerString = answerString+","+answerList.get(i);


            }
            String statusStringOfUserAnswer  = dbhelper.getStatusStringOfUserAnswer(answerList);
            dbhelper.saveOrigionalMarkInDatabase(TotalCountMark,answerString,statusStringOfUserAnswer);  // saves users total marks into database



            Intent intent =new Intent(TestActivity.this,Result.class);
            intent.putExtra("answerString", answerString);
            intent.putExtra("statusStringOfUserAnswer", statusStringOfUserAnswer);
            intent.putExtra("AllResult", count1);
            startActivity(intent);
          finish();
          return;

        } 

これは私のlogcatです：
