User List Implementation and sort them using Collection.sort() 

List<String> list=new ArrayList<String>();
    list.add("A");
    list.add("C");
    list.add("A");
    list.add("B");
    list.add("A");

    System.out.println(list);
    Collections.sort(list);
    System.out.println(list);

But if you are using you object in collection then Implement Comparable interface and override compare(Object obj,Object obj1) method.

Otherwise you can write your Comparator then pass it to sort method.

List, along with Collection.sort() would fit your needs.
