best way to store a list of strings

Question

What would be the best way to store and read a really long string, with each entry is an index for another array?

Right now I have this

String indices="1,4,6,19,22,54,....."

The string has up to hundred of thousand entries, so I think maybe I could use a data structure like Linked List. Does anyone know if it would be faster to use one?

Answer 1

List<String> list = new ArrayList<String>();

list.add("1");
list.add("2");

you need to declare arraylist of type string.Then add to it.
