关于Enumeration遍历问题，困扰很久了，hasMoreElements无法遍历 谢谢

import java.util.*;
import java.util.Enumeration;

public class UserList {

	private static final UserList userList=new UserList();
	private  Vector<String> vec;
	private  UserList()
	{
		vec=new Vector<String>();
	}
	public static UserList getInstance()
	{
		return userList;	
}
public void addUser(String name)
{
	if(name!=null)
		vec.addElement(name);

}
public void removeUser(String name)
{
	if(name!=null)
		vec.remove(name);
}
public Enumeration<String> getUserList()
{
	return vec.elements();
	}
public int getUserCount()
{
	return vec.size();
}
	
}

///////helloword.java

import java.util.Enumeration;

public class helloword {
	public static void main(String[] args )
	{		
		UserList ul=UserList.getInstance();
		  
		System.out.println("当前在线用户:");
		 ul.addUser("AA");
		 ul.addUser("BB");
		 System.out.println(ul.getUserCount());
		  Enumeration<String> enums=ul.getUserList();
		  int i=0;
		  System.out.println(enums.hasMoreElements());
//		  System.out.println(enums.nextElement());
//		  System.out.println(enums.hasMoreElements());
//		  System.out.println(enums.nextElement());
//		  System.out.println(enums.hasMoreElements());
//		  System.out.println(enums.nextElement());

			  while(enums.hasMoreElements());
			  {
				 String v=(String)enums.nextElement();
				 System.out.println(v);
			  }
	}
}

while(enums.hasMoreElements()); 把这个分号去掉即可

呵呵，楼上的眼真尖啊，这个失误不应该，楼主还得多写

是得多写 确实不应该 谢谢
