队列的java实现

import java.util.Vector;

public class VectorDemo {
    static String[] months = {"Janunary","February","March","aprile","May","June","July","Aug","Sep",
            "October","November"};
    public static void main(String[] args) {
        
        Vector vq  =new Vector();
        
        for(int i=0;i<months.length;i++){
            vq.addElement(months[i] + " ");        //进队列对象放入尾部
        }
        
        if(vq.isEmpty()){
            System.out.println("kong");
        }
        
        while(!vq.isEmpty()){                    //出队列从头部取
            System.out.println(vq.firstElement());
            vq.removeElement(vq.firstElement());
        }
        
        vq.clear();
    }
}

输出结果为：

Janunary
February
March
aprile
May
June
July
Aug
Sep
October
November
