ArrayDeque clone() Method in Java
The Java.util.ArrayDeque.clone() method is used to return a shallow copy of this deque. It just creates a copy of the deque.
Syntax:
Array_Deque.clone()
Parameters: The method does not take any parameter.
Return Value: The method just returns a copy of the ArrayDeque.
Below programs illustrate the Java.util.ArrayDeque.clone() method:
Program 1:
// 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]
Program 2:
// Java code to illustrate clone()import java.util.*; public class ArrayDequeDemo { public static void main(String args[]) { // Creating an empty ArrayDeque ArrayDeque<Integer> de_que = new ArrayDeque<Integer>(8); // 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); // Creating another array to copy Deque<Integer> copy_deque = de_que.clone(); // Displaying the copy of Deque System.out.println("The cloned array is: " + copy_deque); }} |
Output:
ArrayDeque: [10, 15, 30, 20, 5] The cloned array is: [10, 15, 30, 20, 5]
