队列的java实现 

 1 import java.util.Vector;
 2 
 3 public class VectorDemo {
 4     static String[] months = {"Janunary","February","March","aprile","May","June","July","Aug","Sep",
 5             "October","November"};
 6     public static void main(String[] args) {
 7         
 8         Vector vq  =new Vector();
 9         
10         for(int i=0;i<months.length;i++){
11             vq.addElement(months[i] + " ");        //进队列对象放入尾部
12         }
13         
14         if(vq.isEmpty()){
15             System.out.println("kong");
16         }
17         
18         while(!vq.isEmpty()){                    //出队列从头部取
19             System.out.println(vq.firstElement());
20             vq.removeElement(vq.firstElement());
21         }
22         
23         vq.clear();
24     }
25 }

输出结果为：

Janunary
February
March
aprile
May
June
July
