Java Collections - ArrayDeque.removeLast() Examples

Java Collections Java Java API

Class:

java.util.ArrayDeque

Method:

public E removeLast()

Retrieves and removes the last element of this deque. This method differs from pollLast() only in that it throws an exception if this deque is empty.

Examples

package com.logicbig.example.arraydeque;

import java.util.ArrayDeque;
import java.util.List;

public class RemoveLastExample {

    public static void main(String... args) {
        ArrayDeque<Integer> ad = new ArrayDeque<>(List.of(3, 8, 1));
        System.out.println(ad);
        Integer i = ad.removeLast();
        System.out.println(i);
        System.out.println(ad);
    }
}

Output

[3, 8, 1]
1
[3, 8]

package com.logicbig.example.arraydeque;
