Java Collections - ArrayDeque.element() Examples

Class:

This method is equivalent to getFirst().

Examples

    public static void main(String... args) {
        ArrayDeque<Integer> ad = new ArrayDeque<>(List.of(3, 2, 5, 7));
        Integer element = ad.element();
        System.out.println(element);
        element = ad.element();
        System.out.println(element);
    }
