Question

Assume that aList is a valid ArrayList containing the following:

Wei, Marila, Anna, Neal, Rachel, Jack, Aneesh

Which of the following does not remove Anna from aList?

1. aList.remove("Anna", 3);
2. aList.remove(2, "Anna");
3. aList.remove(2);

a	Statement I only
b	Statement II only
c	Statement III only
d	Statements I and II only
e	Statements II and III only

Answer 1

Arrays are 0 based collections where the items in the array are indexed starting with zero as the first number.

Your array, indexed in order looks like this

0 - Wei,

1 - Marila,

2 - Anna,

3 - Neal,

4 - Rachel,

5 - Jack,

6 - Aneesh

Since Anna is at position 2, you can eliminate the #1 option of aList.remove("Anna", 3); since Anna is not in position 3.

The syntax to remove an item from a list in java uses the index only of the item you wish to remove. Meaning, a call to remove that looks like #2 would result in a compile time error since aList.remove(2, "Anna"); there is no string argument in the remove method.

This leaves the correct call being #3 being aList.remove(2); where the argument in the remove method is index 2 and matches the example numbering i laid out.

So the answer to your question would be D, options 1 and 2 only do not remove Anna from the list
