Answer 1

Alternatively you can use TreeSet.

public static void main(String[] args){
    Set s1 = new TreeSet(String.CASE_INSENSITIVE_ORDER);
    s1.addAll(Arrays.asList(new String[] {"a", "b", "c"}));

    Set s2 = new TreeSet(String.CASE_INSENSITIVE_ORDER);
    s2.addAll(Arrays.asList(new String[] {"A", "B", "C"}));

    System.out.println(s1.equals(s2));
}
