Adding Elements: add a single element : LinkedList « Collections « Java Tutorial

Adding the element to the end of the list unless an index is specified.

public boolean add(Object element)
public boolean add(int index, Object element)

To Treat the linked list as a stack or queue:

public boolean addFirst(Object element)
public boolean addLast(Object element)

The addLast() method is equivalent to call add(), with no index.

import java.util.LinkedList;

public class MainClass {
  public static void main(String[] a) {

    LinkedList list = new LinkedList();
    list.add("A");
    list.add("B");
    list.add("C");
    list.add("D");
    list.addFirst("X");
    list.addLast("Z");

    System.out.println(list);
  }
}

[X, A, B, C, D, Z]
