How to convert a String into an ArrayList?

Question

In my String, I can have an arbitrary number of words which are comma separated. I wanted each word added into an ArrayList. E.g.:

String s = \"a,b,c,d,e,...         


        

Answer 1

Option1:

List list = Arrays.asList("hello");

Option2:

List list = new ArrayList(Arrays.asList("hello"));

In my opinion, Option1 is better because

1. we can reduce the number of ArrayList objects being created from 2 to 1. asList method creates and returns an ArrayList Object.
2. its performance is much better (but it returns a fixed-size list).
