 Main.java
 */import java.util.*;public class Main {
   private LinkedList list = new LinkedList();
   public void push(Object v) {
      list.addFirst(v);
   }
   public Object top() {
      return list.getFirst();
   }
   public Object pop() {
      return list.removeFirst();
   }
   public static void main(String[] args) {
      Main stack = new Main();
      for (int i = 30; i < 40; i++)
         stack.push(new Integer(i));
      System.out.println(stack.top());
      System.out.println(stack.pop());
      System.out.println(stack.pop());
      System.out.println(stack.pop());
   }}

The output result of running the above code is:

39
39
38
37

The above is the Java example - getting the content of the elements of the linked list, more related Please pay attention to the PHP Chinese website (www.php.cn) for content!
