Sort Arabic words in android

I have a list of Arabic words.

الأ َ ح د د, الاثن َ ين, الث ُّ لاثاء, الأ َ ربعاء, الخ َ ميس, الج ُ معة, الس َّ بت

How to sort it (sort alphabetically)?

updated:

how can i set arrabicCollator in Collections?

    Locale arrabic= new Locale("ar");
    Collator arrabicCollator = Collator.getInstance(arrabic);

    Collections.sort(arr_items, new Comparator<Helper>() {


        @Override
        public int compare(Helper one, Helper two) {
            // TODO Auto-generated method stub
            return one.getTitle().compareTo(two.getTitle());
        }

    });

      

        
        
        
      

    

solved:

    Locale arabic = new Locale("ar");
    final Collator arabicCollator = Collator.getInstance(arabic);


    Collections.sort(arr_items, new Comparator<Helper>() {


        @Override
        public int compare(Helper one, Helper two) {
            // TODO Auto-generated method stub

            return arabicCollator.compare(one.getTitle(), two.getTitle());
        }

    });

      

        
        
        
      

    

helper

is a class that includes setter and getter functions, and arr_items

is an array if the helper:

ArrayList arr_items = new ArrayList <> ();
