Use addFirst method to add value to the first position in a linked list

       
import java.util.LinkedList;

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

    LinkedList<String> officers = new LinkedList<String>();
    officers.addFirst("B");
    officers.addFirst("B");
    officers.addFirst("H");
    officers.addFirst("P");
    officers.addFirst("M");
    for (String s : officers)
      System.out.println(s);
  }
}
