    for (String temp : list){
        System.out.println(temp);
    }

    System.out.println("Set example .....");
    Set<String> set = new HashSet<String>();
    set.add("1");
    set.add("2");
    set.add("3");
    set.add("4");
    set.add("1");
    set.add("2");
    set.add("5");

    for (String temp : set){
