Answer 1

String csv = "Apple, Google, Samsung";

step one : converting comma separate String to array of String

String[] elements = csv.split(",");

step two : convert String array to list of String

 List fixedLenghtList = Arrays.asList(elements);

step three : copy fixed list to an ArrayList ArrayList listOfString = new ArrayList(fixedLenghtList);

System.out.println("list from comma separated String : " + listOfString);

System.out.println("size of ArrayList : " + listOfString.size()); Output :

list of comma separated String : [Apple, Google, Samsung]


size of ArrayList : 3
