How to get values from database to set valies ina list view according to alpherbatical order

This is my code so far to retrive values from database to the listview. I need to make them appear according to alphabetical order. How should I change this code? Please help!

  public List<Units> getAllUnit() {
          List<Units> unit = new ArrayList<Units>();

          SQLiteDatabase db = getWritableDatabase();
         Cursor cursor = db.rawQuery("SELECT * FROM " + TABLE_UNITS,  null);

         if (cursor.moveToFirst()) {
              do {
                unit.add(new Units(Integer.parseInt(cursor.getString(0)) , cursor.getString(1), cursor.getString(2), cursor.getString(3)));
        }
             while (cursor.moveToNext());
         }
         cursor.close();
         db.close();
         return unit;
      }
