Convert String month to integer java

How do I convert a month string to integer?

On click method I want to display the date which is selected but if the date has an event it should display something more about the event. The method to check for the holiday event requires integer values.

Here's the code:

UPDATED:

@Override
public void onClick(View view)
    {
        int m = 0;
        int d, y;
        String date_month_year = (String) view.getTag();
        selectedDayMonthYearButton.setText("Selected: " + date_month_year);

        String [] dateAr = date_month_year.split("-");
        Log.d(tag, "Date Split: " + dateAr[0] + " " + dateAr[1] + " " + dateAr[2]);
        y = Integer.parseInt(dateAr[2]);



        try {
            Calendar c1 = Calendar.getInstance();
            c1.setTime(new SimpleDateFormat("MMM").parse(dateAr[1]));
            m = c1.get((Calendar.MONTH) + 1);
        } 
        catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        //int m = Integer.parseInt(dateAr[1]);
        d = Integer.parseInt(dateAr[0]);
        Log.d(tag, "Date forward: " + d + " " + m + " " + y);

        if (isHoliday(d, m, y))
        {
            Intent i = new Intent(view.getContext(), HijriEvents.class);
            i.putExtra("date_string", date_month_year);
            startActivity(i);

        }


        try
            {
                Date parsedDate = dateFormatter.parse(date_month_year);
                Log.d(tag, "Parsed Date: " + parsedDate.toString());

            }
        catch (ParseException e)
            {
                e.printStackTrace();
            }
    }

    public Boolean isHoliday(int d, int m, int y)
    {
        HijriCalendar hijri = new HijriCalendar(y, m, d);
        if (!hijri.checkIfHoliday().contentEquals(""))
            return true;
        return false;
    }

Calendar cal = Calendar.getInstance();
cal.setTime(new SimpleDateFormat("MMM").parse("July"));
int monthInt = cal.get(Calendar.MONTH) + 1;
