ArrayDeque clone() Method in Java

Last Updated : 11 Jul, 2018

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

// 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

// 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]

ArrayDeque in Java

In Java, the ArrayDeque is a resizable array implementation of the Deque interface, which stands for double-ended queue. It allows elements to be added or removed from both ends efficiently. It can be used as a stack (LIFO) or a queue (FIFO).ArrayDeque grows dynamically.It generally provides faster

ArrayDeque add() Method in Java

The Java.util.ArrayDeque.add(Object element) method in Java is used to add a specific element at the end of the Deque. The function is similar to the addLast() method of ArrayDeque in Java. Syntax: Array_Deque.add(Object element) Parameters: The parameter element is of the type ArrayDeque and refers

ArrayDeque addFirst() Method in Java

The java.util.ArrayDeque.addFirst(Object element) method in Java is used to insert a specific element at the front of this deque. Syntax: Array_Deque.addFirst(Object element) Parameters: The parameter element is of the type ArrayDeque and refers to the element to be added. Return Value: The function

ArrayDeque addLast() Method in Java

The java.util.ArrayDeque.addLast(Object element) method in Java is used to insert a specific element at the end of this deque. It is similar to the add() method in Java. Syntax: Array_Deque.addLast(Object element) Parameters: The parameter element is of the type ArrayDeque and refers to the element

ArrayDeque clear() Method in Java

The Java.util.ArrayDeque.clear() method in Java is used to remove all of the elements from the Deque. Using the clear() method only clears all the element from the deque and does not delete the deque. In other words, it can be said that the clear() method is used to only empty an existing ArrayDeque

ArrayDeque size() Method in Java

The Java.util.ArrayDeque.size() method in Java is used to get the size of the Deque or the number of elements present in the Deque. Syntax: Array_Deque.size() Parameters: The method does not take any parameter. Return Value: The method returns the size or the number of elements present in 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 J

ArrayDeque contains() Method in Java

The Java.util.ArrayDeque.contains() method in Java is used to check or verify whether a specific element is present in the Deque or not. Syntax: Array_Deque.contains(Object element) Parameters: The parameter element is of the type of ArrayDeque. This is the element that needs to be tested if it is p

ArrayDeque iterator() Method in Java

The Java.util.ArrayDeque.iterator() method is used to return an iterator of the elements of the ArrayDeque. Syntax: Iterator iterate_value = Array_Deque.iterator(); Parameters: The method does not take any parameter. Return Value: The method iterates over the elements of the deque and returns the va

ArrayDeque descendingIterator() Method in Java

The Java.util.ArrayDeque.descendingIterator() method is used to return an iterator of the same elements as the ArrayDeque but in the reverse order. Syntax: Iterator iterate_value = Array_Deque.descendingIterator(); Parameters: The method does not take any parameter. Return Value: The method iterates
