Question 12: Consider the Java code given below. What will the output…

1import java.util.*;
2public class SetExample {
3    public static void main(String[] args) {
4        LinkedList<String> list = new LinkedList<String>();
5        list.add("Apple");
6        list.add("Samsung");
7        list.add("Nokia");
8        list.add("Samsung");
9        Set<String> set1 = new LinkedHashSet<String>();
10        Set<String> set2 = new TreeSet<String>();
11        for (String str : list) {
12            set1.add(str);
13            set2.add(str);
14        }
15        for (String str : set1) {
16            System.out.print(str + " ");
17        }
18        System.out.println();
19        for (String str : set2) {
20            System.out.print(str + " ");
21        }
22    }
23}
