初始化的一些问题(Vector使用)

 1 import java.util.Vector;
 2 import java.util.Iterator;
 3 import java.util.Arrays;
 4 import java.util.ArrayList;
 5 public class VectorDemo{
 6    public static void main(String args[]){
 7       String names[]={"hfdsfng", "zhfcinyafdn"};
 8       String namesp[]=new String[]{"hv  heng", "zhavxcyan"};
 9       Vector<String> v1=new Vector<String>(
10            Arrays.asList("hujghfgeng", "zhagfyan", "huaxvvidong")
11        );
12       Vector<String> v2=new Vector<String>(Arrays.asList(names));//Arrays.asList()返回List列表(继承了Collection)
13       Vector<String> v3=new Vector<String>(new ArrayList<String>(){//匿名类的初始化,ArrayLists类实现了Collection接口
14           {
15              add("hujunzheng");
16           add("zhangjinyan");
17           }
18       });
19      //三种实现遍历Vector的方法
20      System.out.println("V1向量:");
21      for(Object tmp : v1.toArray()){
22          System.out.println((String)tmp);
23      }
24 
25      System.out.println("V2向量:");
26      for(Iterator<String>it = v2.iterator(); it.hasNext(); ){
27          System.out.println(it.next());
28      }
29 
30      System.out.println("V3向量:");
31      for(int i=0; i<v3.size(); ++i){
32         System.out.println(v3.elementAt(i));
33      }
34    }
35 }
