Arraylist

Question

Say whether following statements are correct or not???
1.List<Integer>fan=new ArrayList<>();
2.List<Integer>fan=new LinkedList<>();

3.Queue<Integer>fan=new Linkedlist<>();

Answer 1

The first two are correct but the last one isn't - there's a syntax error, "Linkedlist" doesn't exist. As long as you import Java's utility module, the first two should work.

Answer 2

Are you confused on what is being asked?

Answer 3
