E remove(): Retrieves and removes the head (first element) of this list.
E remove(int index): Removes the element at the specified position in this list.
boolean remove(Object o): Removes the first occurrence of the specified element from this list, if it is present.
E removeFirst(): Removes and returns the first element from this list.
boolean removeFirstOccurrence(Object o): Removes the first occurrence of the specified element in this list (when traversing the list from head to tail).
E removeLast(): Removes and returns the last element from this list.
boolean removeLastOccurrence(Object o): Removes the last occurrence of the specified element in this list (when traversing the list from head to tail).


import java.util.LinkedList;

public class Main{
    public static void main(String args[]) {
        LinkedList<String> ll = new LinkedList<String>();

        ll.add("A");
        ll.add("java2s.com");
        ll.add("B");
        ll.add("C");
        ll.add("java2s.com");


        String str = ll.remove();
        System.out.println(str);
        System.out.println(ll);
    }
}

The output:


A
[java2s.com, B, C, java2s.com]
