    public class SortIgnoreCase implements Comparator {
    public int compare(Object o1, Object o2) {
        String s1 = (String) o1;
        String s2 = (String) o2;
        return s1.toLowerCase().compareTo(s2.toLowerCase());
    }
}



    then
    


    Collections.sort(ArrayList, new SortIgnoreCase());
