Create a new ArrayList<String>, traverse the "mylist", append one after one element into newly created list and finally use toArray(T[]) method of newly created list to obtain a string array.

You are right.But if he will create ArrayList<String>.He can directly add those into array.Is not it ? – Android Killer Sep 29 '11 at 5:29
@AndroidPower yes! of course. – AVD Sep 29 '11 at 5:31
So why should he create Arralist<String> ? He can take add the item directly to String array. – Android Killer Sep 29 '11 at 5:36
@AndroidPower - how she/he will determines the count of strings in that collection? – AVD Sep 29 '11 at 5:41
