Create ArrayList from array 32 answers

You need to create it like this:

private ArrayList<String> booksList = new ArrayList<String>(Arrays.asList(books));

new ArrayList<String>(Arrays.asList(books)) is the part which is turning your array into an ArrayList .

You could also do:

private List<String> booksList = Arrays.asList(books);

If the fact that it is an ArrayList doesn't matter.

Answered here

new ArrayList<Element>(Arrays.asList(array))

*** new
