Yes, it works at the playground.
Make sure you imported it:
import java.util.ArrayList;

I think he didn't, because then it would result in a type error. But both answers combined will make the solution ^^

//You are adding ArrayList<Integer> with a String.
//You need to change with the follows :
import java.util.*;
ArrayList<String> sample = new ArrayList<String>();
sample.add("example");
// this will work
