Answer 1

String s1 = new String("10201");
String s2 = new String("01341");


//intersect
HashSet<Character> h1 = new HashSet<Character>(), h2 = new HashSet<Character>();
for(int i = 0; i < s1.length(); i++)                                            
{
    h1.add(s1.charAt(i));
}
for(int i = 0; i < s2.length(); i++)
{
    h2.add(s2.charAt(i));
}

//union
h1.addAll(h2);

//intersect
h1.retainAll(h2);
