To remove the first or the last elements from the linked list we can use the removeFirst() and removeLast() methods provided by the LinkedList class.

package org.kodejava.util;

import java.util.LinkedList;

public class LinkedListRemoveItems {
    public static void main(String[] args) {
        LinkedList<String> grades = new LinkedList<>();
        grades.add("A");
        grades.add("B");
        grades.add("C");
        grades.add("D");
        grades.add("E");
        grades.add("F");

        System.out.println("Original values are:");
        System.out.println("====================");
        for (String grade : grades) {
            System.out.println("Grade: " + grade);
        }

        grades.removeFirst();
        grades.removeLast();

        System.out.println("New values are:");
        System.out.println("====================");
        for (String grade : grades) {
            System.out.println("Grade: " + grade);
        }
    }
}

This program print out the following result:

Original values are:
====================
Grade: A
Grade: B
Grade: C
Grade: D
Grade: E
Grade: F
New values are:
====================
Grade: B
Grade: C
Grade: D
Grade: E
