StringTokenizer的怪现象

[superrg]

StringTokenizer stRcpt = new StringTokenizer("mail@mailserver","@@");
用
stRcpt.nextToken()
竟然返回
mail
mailserver
而不是期望的
mail@mailserver
何解？？

[cbhyk]

delimiters (the characters that separate tokens)
StringTokenizer是按delimiters中的每一个字符分解的, 如StringTokenizer st = new StringTokenizer("a3bc1def1gh", "13"); 分解的结果是a,bc,def,gh

晕，那有没有按字符串分隔的？？

老大,在StringTokenizer stRcpt = new StringTokenizer("mail@mailserver","@@");
中,"@@"是个终止付串.它的每个字符都是终止附;
"@_ ,"这个字符串代表:'@',',',' ','_'这四个字符都是终止符.

没有解决办法吗？？

[cbhyk]

public static String[] split(String s, String separator)
{
if(s == null)
throw new NullPointerException("source String cannot be null");
if(separator == null)
throw new NullPointerException("separator cannot be null");
if(separator.length() == 0)
throw new IllegalArgumentException("separator cannot be empty");

ArrayList tmp = new ArrayList();
int start = 0;
int separatorLen = separator.length();
int end = s.indexOf(separator);
while(end != -1)
{
tmp.add(s.substring(start, end));
start = end + separatorLen;
end = s.indexOf(separator, start);
}
tmp.add(s.substring(start, s.length()));
String[] result = new String[tmp.size()];
tmp.toArray(result);
return result;
}

public static void main(String[] args)
{
String[] result = split("a,,b,c,,d", ",");
for(int i=0; i<result.length; i++)
System.out.println(result[i]);
}

干吗要拿字符串当分隔符，找一些冷僻的字符，不可以吗，
要知道unicode的最多可以有2^16=65536个哪，我想总有几个适合你
