can anyone explain the unchecked warning that is given in line 3 and why it occurs

 1)        List<Integer> a = java.util.Arrays.asList(1, 2, 3);
2)        List<Integer> b = java.util.Arrays.asList(4, 5, 6);
3)        List<List<Integer>> x = java.util.Arrays.asList(a, b);

There is no line 3.
All of your code is in a single line.

If you click the icon in your first post, you will be able to edit it to make it more readable.

Thank you for editing your post.

Why do you think it occurs in no 3 and not in no 1 and 2?

Because that's what the compiler tells you. I tried, and got the warning on line 3.

Now that's a really helpful answer!
