LinkedList get elements

In this chapter you will learn:

1. Get the element from LinkedList

Get the element from LinkedList

The following methods get elements from LinkedList in various positions.

• E get(int index)
  Returns the element at the specified position in this list.
• E getFirst()
  Returns the first element in this list.
• E getLast()
  Returns the last element in this list.

import java.util.LinkedList;
//from  j  av  a  2s .com
public class Main{
    public static void main(String args[]) {
        LinkedList<String> ll = new LinkedList<String>();

        ll.add("A");
        ll.add("ja v a2s.com");
        ll.add("B");
        ll.add("C");


        System.out.println(ll.get(1));
        System.out.println(ll.getLast());
        System.out.println(ll.getFirst());
    }
}
