The java.util.ArrayDeque.element() method in Java is used to retrieve or fetch the head of the ArrayDeque. In the process, the method does not delete the element from the deque instead it just returns the element.
Syntax:
Array_Deque.element()
Parameters: The method does not take any parameter.
Return Value: The method returns the element present at the head of the Deque.
Below programs illustrate the Java.util.ArrayDeque.element() method:
Program 1:
// Java code to illustrate ArrayDeque element() methodimport java.util.*;  public class ArrayDequeDemo {    public static void main(String args[])    {        // Creating an empty ArrayDeque        ArrayDeque<String> de_que = new ArrayDeque<String>();          // Use add() method to add elements into the Deque        de_que.add("Welcome");        de_que.add("To");        de_que.add("Geeks");        de_que.add("4");        de_que.add("Geeks");          // Displaying the ArrayDeque        System.out.println("ArrayDeque: " + de_que);          // Displaying the head        System.out.println("The head element is: " + de_que.element());    }} |
Output:
ArrayDeque: [Welcome, To, Geeks, 4, Geeks] The head element is: Welcome
Program 2:
// Java code to illustrate ArrayDeque element() methodimport java.util.*;  public class ArrayDequeDemo {    public static void main(String args[])    {        // Creating an empty ArrayDeque        ArrayDeque<Integer> de_que = new ArrayDeque<Integer>();          // Use add() method to add elements into the Deque        de_que.add(10);        de_que.add(15);        de_que.add(30);        de_que.add(20);        de_que.add(5);          // Displaying the ArrayDeque        System.out.println("ArrayDeque: " + de_que);          // Displaying the head        System.out.println("The head element is: " + de_que.element());    }} |
Output:
ArrayDeque: [10, 15, 30, 20, 5] The head element is: 10
