这是清华大学编写的JAVA教材中所有题目的源代码！

import java.util.*;

class StackDemo
{
	public static void main(String[] args)
	{
		Stack s=new Stack();
		
		s.push(new String("hello"));
		s.push(new Double(2.2));
		s.push(new Date());
		
		Enumeration e=s.elements();
		while(e.hasMoreElements())
			System.out.println(e.nextElement());
		System.out.println();
			
		while(!s.empty())
			System.out.println(s.pop());
		System.out.println();
		
		System.out.println("size="+s.size());
	}
