The following example demonstrates how to use the addFirst() and addLast() methods of the LinkedList class to add elements at the beginning and end of the linked list:
/* author by w3cschool.cc Main.java */import java.util.LinkedList;public class Main { public static void main(String[] args) { LinkedList lList = new LinkedList(); lList.add("1"); lList.add("2"); lList.add("3"); lList.add("4"); lList.add("5"); System.out.println(lList); lList.addFirst("0"); System.out.println(lList); lList.addLast("6"); System.out.println(lList); }}
The output result of running the above code is:
1, 2, 3, 4, 5 0, 1, 2, 3, 4, 5 0, 1, 2, 3, 4, 5, 6
The above is a Java example - adding elements at the beginning and end of a linked list (LinkedList). For more related content, please pay attention to the PHP Chinese website (www.php.cn)!
