Answer 1

You can do with custom Comparator.

Try this:

    // list containing String objects
    List list = new ArrayList<>();

    // call sort() with list and Comparator which
    // compares String objects ignoring case
    Collections.sort(list, new Comparator(){
        @Override
        public int compare(String o1, String o2) {
            return o1.compareToIgnoreCase(o2);
        }
    });

You will need to pass Comparator instance in Collections.sort() method which compares String objects ignoring case.
