Syntax: str [j] = a1.get (j) Approach: Get the ArrayList of Strings. Example: Java The arraylist size can be found using size () method of ArrayList class. We have used the split() method to convert the given string into an array. The statement String arr [] = new String [arrList.size ()]; creates an array arr of string type with the .
