2. 
   
3. import java.util.ArrayList;
4. import java.util.List;

14. public static void main(String[] args) {
16. List<String> lstflowers = new ArrayList<String>();
17. lstflowers.add("Rose");
18. lstflowers.add("Lilly");
19. 
    
20. String[] arrayflower = new String[lstflowers.size()];
21. arrayflower = lstflowers.toArray(arrayflower);
22. 
    
23. for(String flower : arrayflower)
24.     System.out.println(flower);
25. }
26. 
    
27. }
