Output:
[]
Explanation:
As one would expect, attempting to access a member of a list using an index that exceeds the number of members (e.g., attempting to access list[10] in the list above) results in an IndexError. However, attempting to access a slice of a list at a starting index that exceeds the number of members in the list will not result in an IndexError and will simply return an empty list.

Answer: d
Explanation: obj is an object of class ArrayLists hence it is an dynamic array which can increase and decrease its size. obj.add(“X”) adds to the array element X and obj.add(1,”X”) adds element x at index position 1 in the list, Hence obj.add(1,”D”) stores D at index position 1 of obj and shifts the previous value stored at that position by 1.
Output:
$ javac Arraylist.java
$ java Arraylist
[A, D, B, C].
