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:
Java
Java
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:
Program 2:
ArrayDeque: [Welcome, To, Geeks, 4, Geeks] The cloned array is: [Welcome, To, Geeks, 4, Geeks]
// 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]
