Can we use index like array index to access List?

Question

I am wondering if we can use index to access List

For example:

List list; 

list[5]     //blah....

Answer 1

an alternative to using get(int) is to create an Array using toArray()

List list = ...

Object[] array = list.toArray();

if T is known, toArray(T[]) can be used to return T[] instead of Object[].
The use of toArray is only meaningful, instead of get, if an array is really needed (lots of accesses).
