import java.util.*;

public class StackApp {

  static String[] months = {
    "January", "February", "March", "April",
    "May", "June", "July", "August", "September",
    "October", "November", "December" };

  public static void main(String[] args) {
    Stack stk = new Stack();

    for(int i = 0; i < months.length; i++)
      stk.push(months[i] + " ");

    System.out.println("stk = " + stk);

    // Treating a stack as a Vector:
    stk.addElement("The last line");
    System.out.println(
      "element 5 = " + stk.elementAt(5));

    System.out.println("popping elements:");

    while(!stk.empty())
      System.out.println(stk.pop());
  }
} 


运行结果：

stk = [January , February , March , April , May , June , July , August , September , October , November , December ]
element 5 = June 
popping elements:
The last lineDecember November October September August July June May April March February January
