dayArray[dayOfWeek-1] 이건 어떻게 해석하나요?

java

package sec02.verify.exam02;

import java.util.Calendar;

public class DatePrintExample2 {

    public static void main(String[] args) {

        Calendar now = Calendar.getInstance();

        int year = now.get(Calendar.YEAR);

        int month = now.get(Calendar.MONTH)+1;
        String strMonth = (month<10) ? ("0"+month) : (""+month);

        int dayOfMonth = now.get(Calendar.DAY_OF_MONTH);
        String strDayOfMonth = (dayOfMonth<10)? ("0"+dayOfMonth) : (""+dayOfMonth);

        String[] dayArray = {"일", "월", "화", "수", "목", "금", "토"};
        int dayOfWeek = now.get(Calendar.DAY_OF_WEEK);
        String strDayOfWeek = dayArray[dayOfWeek-1] + "요일";

        int hour = now.get(Calendar.HOUR_OF_DAY);
        String strHour = (hour<10) ? ("0"+hour) : (""+hour);

        int second = now.get(Calendar.SECOND);
        String strSecond = (second<10) ? ("0"+second) : (""+second);

        System.out.print(year + "년 ");
        System.out.print(strMonth + "월 ");
        System.out.print(strDayOfMonth + "일 ");
        System.out.print(strDayOfWeek + " ");
        System.out.print(strHour + "시 ");
        System.out.print(strSecond + "분 ");

      }
    }

여기서 String[] dayArray = {"일", "월", "화", "수", "목", "금", "토"}; 이렇게 배열 선언하고 이 변수 dayArray 안에 다시 리스트 [dayOfWeek-1] 를 대입?하는건 어떻게해석해야하는건지모르겠어요
