// Java code to illustrate clone()
import 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);
  
        // Creating another array to copy
        Deque<String> copy_deque = de_que.clone();
  
        // Displaying the copy of Deque
        System.out.println("The cloned array is: " + copy_deque);
    }
}

Output:

ArrayDeque: [Welcome, To, Geeks, 4, Geeks]
The cloned array is: [Welcome, To, Geeks, 4, Geeks]

Output:

ArrayDeque: [10, 15, 30, 20, 5]
The cloned array is: [10, 15, 30, 20, 5]
