What is Deque.remove() method in Java?
The Deque.remove() method is used to remove the head element from a deque. The Deque.remove() method is present in the Deque interface inside the java.util package.
Syntax
Deque.element remove()
Parameter
The Deque.remove() method doesn’t take any parameters.
Return
The Deque.remove() method returns the element present at the head of the deque, which is being removed.
Code
Let’s take a look at the code snippet below.
import java.util.*;class Main{public static void main(String[] args){Deque<Integer> d = new LinkedList<Integer>();d.add(212);d.add(23);d.add(621);d.add(1280);d.add(3121);d.add(18297);d.add(791);System.out.println("Elements of the deque are: " +d);d.remove();System.out.println("Elements in the deque are: "+d);}}
Explanation
- In line 1, we imported the required package.
- In line 2, we made a
Mainclass. - In line 4, we made a
mainfunction. - In line 6, we declared a deque consisting of
Integertype elements. - From lines 8-14, we inserted the elements in the deque by using the
Deque.add()method. - In line 16, we displayed all the deque elements.
- In line 18, we removed the head element from the deque by using the
remove()method. - In line 20, we displayed the deque elements after removing the elements.
In this way, we can use Deque.remove() method in Java.
