几个简单的java学习代码

import java.util.*;

public class HashtableApp {

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

 public static void main(String[] args) {
    Vector v = new Vector();
    for(int i = 0; i < 7; i++)
      v.addElement("vector"+i);

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

    Hashtable h= new Hashtable();
    h.put("vec",v );
    h.put("stack",stk);

    Stack newStack = (Stack)h.get("stack");
    Vector newVector =(Vector)h.get("vec");

    while(!newStack.empty())
      System.out.println(newStack.pop());

    for(int i = 0; i < newVector.size() ; i++)
      System.out.print(newVector.elementAt(i) +" ");
    System.out.println();


  }
}


运行结果：

December November October September August July June May April March February January
